I spilled half a bottle of water on my computer and brought it straight away to Chris. He diagnosed it for 95 dollars and fixed the water damage for another 200. The turnaround time was exactly a day! He knows what he's doing and wastes no time in getting the job done. I highly recommend going to Chris for all tech repair needs. read more

Compuwiz - IT Services & Computer Repair Near Me - Diamond Bar, California

Great experience with CompuWiz in Diamond Bar! My laptop suddenly stopped booting up, so I brought it in yesterday afternoon. Chris quickly ran a diagnostic, identified the problem with Windows, called me to explain, and reinstalled the system. Less than 24 hours later, my laptop was ready for pickup. Excellent service, fast turnaround, clear communication and reasonably priced. Lovely husband-and-wife business that I'm happy to support. I highly recommend. read more

I spilt milk tea over my entire Mac book pro. I came to this store and they were able to finish the work in one day for a fraction of what Apple wanted! The computer is fully functional and no permanent damage. Computer wizard for sure read more

After reading the Yelp reviews, I brought my 2016 Lenovo Yoga 900 (bad battery) and 2013 Dell All-in-One (bad hard drive) to Chris since I didn't have time to fix them myself. He replaced the Yoga's battery and upgraded the Dell to an SSD. During his burn-in test (a smart quality check), the Dell failed. Chris tried replacing the motherboard with a used one, but it still wouldn't work. To make things right, he offered me a newer used HP All-in-One and transferred the SSD and 16GB RAM from the Dell. Everything was done in just a few days, impressively fast if you've ever dealt with PC repairs. I've worked in IT for over three decades and managed thousands of desktop and laptop deployments before retiring. I've seen plenty of techs who overcomplicate problems or take forever to diagnose and fix things. Chris isn't one of them. He charges competitive prices, works quickly, and does the job right. Highly recommended. read more

My laptop was damaged after being mishandled by cruise employees and was dented on the top left corner of the frame. It still worked but there was a noticeable gap between the screen and metal housing, so I took it to Chris to see if he could fix it. I also asked for a fresh install of Windows 11 while keeping some of the data on it, and he said he could do that. Within a day I got my laptop back looking almost as good as new and the fresh install went without a hitch! Thank you, Chris, for the excellent service and price! I'll be bringing any future PC-related issues to him! read more

Chris is my go-to guy for any tech troubleshooting. He had fixed my $4k MacBook from water damage before. And now my gaming PC was crashing suddenly after not being used for a few years. Chris was able to diagnose it and turned out to be a faulty power supply. He replaced it for me and my PC runs as good as new now all for a very reasonable price. read more

Thank you so much Chris!! He saved my son's laptop. It had water damage. He was honest from the beginning told us it didn't look good but he was willing to try it. He was able to fix it way faster than he'd estimated. What he thought would take him several days took him less than a day. Awesome service and very affordable. read more

Chris fixed my PC within the same day! I brought my pc to repair due to blue screen issue in the early morning, Chris called me at noon informed me about replacing the unstable motherboard, just like that I got my pc fixed with a reasonable price within the same day! Thank you so much Chris!! read more

$100. Diagnostic . Just told me a generic answer that I need new motherboard at $200 for a Mac When I only needed new re-install of Monterey IOS . When I came to collect my MacBook, he was dismissive , rude ... as I refuse to pay $200 when I could repair it myself after doing re-search . My MacBook was in the same place that I dropped it off the day before . He never touched it, not even moved . He's a liar . read more

Chris was very helpful in diagnosing my problem. He worked tirelessly on my laptop and got to the root of the issue. Thank you Compuwiz!

I was referred to Chris by a friend and colleague years ago, and I've lost count how many times I've brought different Macbooks (2012, 2018) and and an iMac (2011) in for Chris to service since. Each time he was fast and he gauges complzetion time accurately. Also great communication about status, parts shipments, and upfront about fees and parts from the start. Tests machine thoroughly even upon pick up, and the one time that a Macbook would not start after returning it, he was quick to determine it was a faulty replacement battery and replaced it again right away with a battery that worked. I will be continuing to come to him for future service. read more

I have taken my computers to Compwiz for a number of years. The reason I keep going back to them is that I feel the data on my machines is secure and I know they will fix any issues in a timely and cost effective manner. I woud highly recommend them to anyone needing computer repair. read more

Spilled liquid on my macbook and it was a $100 diagnostic fee. He was then able to fix it for ~$250 given the damages in about a week.

I've gone to Chris three times for computer repair. The first time he made my old 2013 computer run like new with a new keyboard, and hard drive. The second time he removed a virus, and the third time he installed a new drive and increased my storage to a terabyte. He performs miracles for extremely reasonable prices. You are in good hands with Chris, it seems like there's nothing he can't do to save your data. Thanks , Chris, I really appreciate your good work. read more

My computer froze trying to run a Microsoft update. Did everything I tried didn't work. Took it to Chris and he found the root cause of the problem. Old, slow and bad hard drive. He replaced it and got everything working like brand new! Highly recommend. read more

Chris is amazing. He fixed my broken screen on my laptop. I thought my laptop needed a new battery and was prepared to pay for one. He could have replaced my battery and I wouldn't have questioned it. But he instead told me my battery was fine and not in need of replacement. That's integrity. I then brought in my desktop and he changed out the hard drive and it now runs as fast as when it was new. The prices are very reasonable and this will be my new one stop shop for computer repair. read more

This is the third time we've used the excellent services at Compuwiz. The first two times were for external drive repairs. He saved my husband's files and charged less than $100, when another shop had said it would cost $3000. The screen on my MacBook Pro was cracked and I took it in. It was replaced with a new screen and the service was exceptionally quick and fairly priced. We will definitely be taking our tech devices and computers to this shop again read more

Although there is a tiny language barrier, Mr. Chris was able to assist me in my PC troubles I have been having for more than a year. I went to him one time when the issue was evolving, and the issue ended up fixing itself. However, it came up again recently, and I went back to Mr. Chris a second time, and he was able to be lenient and understanding. He offered great prices and technological answers, and he was able to fix the issue in less than a day! Praise God for Mr. Chris and his wife, they are awesome people! read more

I have had a couple of laptops repaired from here recently and was very happy with the service. Good work, fast turn around and fair price. read more

Dave B. I have been taking my computers - both desktop & laptop - to Chris for nearly 3 years, but this is my first review. I would not trust my computers with anyone but Chris. He not only knows how to repair computers, but he takes the time to explain to you what the problems are, and he makes suggestions. If it is not worth fixing, he will tell you so. His charges are very reasonable and he is pleasant to speak with. I live nearly 20 miles from Chris, but I would go to him if I lived 50 miles from him. He is highly recommended! read more

Great and fast service! Chris is very nice and professional. Found another damage and didn't charged me for extra. I really appreciate it

Same day call, same day service, hard-working on a holiday, fair pricing, expert tools and experience. Highly recommended for any computer repair! read more

I have been taking all of my computers to Compuwiz for many years and I always receive excellent customer service and reasonable a price. Mr. Kim has consistently provided professional, fast response and expert repair service for me and my family. I will continue to utilize Compuwiz for all of my computer needs. Thank you Mr. Kim. Max R. read more

I was going to recycle a couple of old desk top computers. I was originally going to use those "Geek" people at a large electronics store. I tried to get an appointment but it was not worth the effort. I called these folks, a small, family run business and was very happy I did. Dropped off the computers to extract the files. $50 to see what could be done. Ok. Got called a little later, very reasonable price, including an external drive to store the data. Bottom line, great service, very reasonable charge. All done in less than 3 hours. Very happy with them. I still have a couple of computers to go, will be back. Highly recommend them. Best of all, they are local. I'm not a big fan of the large impersonal stores, and very unimpressed with those Geek people. read more

Chris is amazing! The price is always fair and I always get my laptop back very quickly. I have recommended Compuwiz to friends and they have had the same experience as well. read more

This is a terrible computer repair workshop. Terrible service and charge you a lot of your money. A typical rip you off poor service situation. Be careful! read more

I had a problem with my apple macbook pro. I first took it to the apple store, they charged me $500 for it to get it fixed... I was like forget that...I googled this place.. At first I wasn't quite sure. But what more could I lose?.. Got a diagnostic got a quote and Chris charged almost half of that! Honest guy. He truly is a computer wizard. read more

Chris does a great job. I had a Mac laptop that needed a new battery. The hinge was also damaged, so it would not shut closed all the way. It was also dirty on the inside. Chris installed the battery and replaced the hinge, for a fair price. He also cleaned through the inside at no charge. All done by the next day. Very fast, efficient service. Highly recommended! read more

Excellent nd fast service, my laptop was broken, unable to get out all data, I brought in, I need urgent get job done. they help me check it and recovery data only for four hours, very good price for such excellent service . read more

You know I personally would caution anybody from using this shop to do any kind of repairs or purchases or anything from this guy. I don't like the fact that when you call this guy on the phone and he gives you an estimate on the phone and as soon as you walk in the door he whips out a piece of paper and tells you that there's going to be a diagnostic fee and then a separate repair fee and then he tries to nickel-and-dime you and show you all kinds of add-ons that you don't even need hard drives laptop chargers and whatever okay total rip-off he overcharged Me by $40 plus tax on a $50 fee for a charger that didn't need as soon as I got to my office to test it out the charger didn't even work it took another week in order to return the charger I had to go through all this Hassle and go back to his office over four times you know it's just ridiculous and a waste of time I could have just taken my laptop to a real professional laptop repair service and they would have had it done no questions asked flat fee in the door out the door and you're done you don't walk away with the feeling that you being ripped off or robbed. Sometimes I really hate having to do business with these little mom-and-pop shops where the husband or wife or just hanging out together in the shop in the store all day together you know I try to do business with them I want them to succeed and the first thing they do is rip you off you know how can you continue to build your business when every customer that walks in your door you're going to rip the guy off you know he's never going to come back and then you've lost just lost a customer these people don't understand that the way you succeed in business is when you have repeat customers coming back over and over and also they invite their friends and you build a network of customers that way but no they'd rather just rip you off for $50 and call it a day read more

This is my second time that I'm utilizing Chris's services. The first time (some years ago) it was a hard drive crash, and he recovered the data, made the thing to work like nothing happened. (Thanks!!!) This time I was trying to clone computers (my business computer), and things went wrong without any reasonable explanation (content and the system moved the external drive and I erased it all). It did not look good. To make a long story short, Chris has done a wonderful job, recover my files (actually recover the whole setup), and I am very grateful. It was all done in one day. If I could give him six stars, I would do it in a split second. Highly recommended, quality work, reasonably priced, and the work is done right. Thanks_Richard read more

My favorite place to repair any electronic devices. The owner is very informative and hardwork. You can save a lot of money

I needed a custom RGB computer put together that I was unable to do myself do to recent surgery. Chris was very professional and communicated with me throughout the build. The computer was surprisingly completed very quickly and done well. I'm still in the honeymoon stage with this computer but it's performing perfect so far. I wish his prices were a little lower that's the reason for the four star rating but in the end I'm happy... read more

Great to have a local business that can get the job done fast and efficiently. Replaced a hard drive and installed the basics in a couple of hours. Saved me money, time and potential losses. Thanks, Chris read more

Very professional and great service. I highly recommended for any apple products and PC repair.

Chris is my repairman for all my computer repairs. He is very knowledgeable, accurate and not expensive. He will get diagnosis done for 50.00 and call back within reasonable time with total estimate and explanation of things to be repaired. Once or twice he has advised me to get computer or printer replaced when it was not worth repairing. I have been his customer for more that ten years. And I will continue to get his services as long as I need to get computer repaired. read more

Came in with a small hardware issue and they fixed it asap. They are extremely nice and friendly, and were quick to solve my issue at a very affordable price. I will be coming here for all my future computer and laptop needs :)) read more

Five stars. Highly recommended. ***In early February 2022, my daughter's laptop could not be powered up. Brought it to the computer service department of a big box electronic store (actually a wholly owned subsidiary of the big box store) on a Tuesday afternoon. When I spoke with the tech at the big box store, I learned that I had to make an appointment to drop-off the laptop to be inspected and repaired. I made an appointment to come back the next day to drop off the laptop to have the problem diagnosed; mind you, I was already in the store with the defective laptop when I had to make the appointment to return the next day. Not only did I have to make an appointment to return to the big box store with the laptop, I also learned that the service department did not repair hardware, and if that was the issue, the laptop would have to be sent out to be repaired by a third party, which would take 3 to 6 weeks to complete. ***After leaving the big box store, I found CompuWiz using Google, drove there with the laptop and spoke with Chris. Chris suspected the problem may lie with the laptop's motherboard, but could not be sure until he had a chance to inspect the computer. Chris quoted me a price for the inspection and told me he would call back the same day. True to his word, Chris called and texted me back on the same day. He explained the problem did lie with the motherboard and give me options and costs for the fix. At the end, I elected to buy a new laptop and have Chris migrate the apps and data from the old laptop to the new one. I dropped off the new laptop with Chris after I purchased it, and was told by Chris that it would be ready the following day. Chris actually completed the work the same day. It has been a few months now and, per my daughter, the new laptop is working fine. ***The key take away with CompuWiz and Chris is that they were able to provide very timely, responsive and competent service; especially when compared to the big box store. Note, the tech who helped me at the big box store was very nice and competent. She actually took the time to try and power up the laptop, and she did suspect the problem was with the motherboard. The problem was not with the tech at the big box store; rather, the problem was with the size of the big box store. Because of its size, the big box store has had to implement certain protocols in order to provide its services; protocols which make it very frustrating to use, let alone access. ***CompuWiz and Chris did a great job, would definitely recommend. read more

My MacBook Air wouldn't turn on all of a sudden with all my important files on it... took it to the apple store and quoted me an arm and a leg... so I decided to check out this local store. Chris is the owner and he is very knowledgable, quoted me half the price of what Apple tried to charge me. Got my MacBook back and is as good as new! Highly recommend! read more

Ripped me off . He unplugged the fan that cools computer and said my computer wasn't working. He said my computer would burn up. My boyfriend opened it up and could not believe this idiot did that. Don't go here!!! read more
