So I brought my PC here for a diagnostics. The man at the establishment starts looking at my PC and starts throwing it around all over his repair desk. To the point of one of the USB's plugged in was bent when I got it back. He tells me "GPU and RAM were bad" and thats why my PC wasn't working. I didn't suspect that to be right as he charged me $20 for this service. This man was trying to rob me for the most expensive parts! Like I mentioned, right away I knew what he said was wrong, so I went to another computer place right after, turns out I didn't have a wire properly plugged in and the service was way better. (shoutout ComputerTech Brookhurst) To make matters worse the man at the first repair shop also took my GPU support bracket as well!!! I had to go back the next day and retrieve it, not even a sorry. 0/10 for the costumer service, 0/10 for diagnostics and technical expertise. 0/10 for professionalism and trustworthiness.

I had three or four keys that weren't working on my MacBook Pro keyboard...yikes! I got on Yelp and…read moreI sent my issue to a couple companies. Only Joe from OC Computer bothered to provide a brief, yet informative response. Without seeing my computer, he said I probably needed a new keyboard (palm rest as he called it), and that would be about $350, parts and labor. I was still able to use my computer for most stuff, so I was in no huge hurry. To cover all my bases, I took it to the Apple store in Cerritos just to see what they'd say. They weren't sure, saying I likely needed a new keyboard (as Joe said). When I mentioned the word "palm rest" it was like a foreign language to the guy. To make sure, they said they would have to send my computer off for a week...what? Of course, I asked how much that would be and they said $800...IF that indeed was the problem. Oh yeah, since I didn't have an appointment (my fault) I had to wait about an hour just to get a seat at one of the tables where you actually have a person come talk to you. Then I waited another 20 minutes until someone talked to me. The guy was nice, but I just didn't have a good feeling. After that appointment, I drove directly to OC Computer which is by my house, talked to Joe and Angel, put down a deposit for a new keyboard/palm rest and they called me when the part came in. In the meantime, like I said, I was able to hold on to my computer and use it for some stuff. When I took my laptop in, two days later I had it back and working. I probably could have had it back sooner, but I told them I was in no hurry. Anyway, OC Computer is less than two miles from my house, so I should have gone there first, but that's on me. Next time, if needed, I will. So, while I'm sure the Apple store is good for a lot of things (especially if you have insurance), I would at least talk to Joe and/or Angel and maybe save yourself some time and money. FYI...I waited a couple of weeks to post this Yelp review just in case there were any hiccups. There haven't been any...so, knock on wood. Anyway, thanks Joe and Angel.

Update: 6/22/2018 I'm not sure how Daniel removed my review, but I'm posting this again because my…read moreexperience with Daniel was horrible and I want to warn everyone and to take your business elsewhere. If you guys can go anywhere else to fix our PC please do so. I took mine in to have it repaired for bad graphics or bad ram and regret it deeply. I texted daniel yesterday night after seeing the good reviews and how close he was to me. Little did I know I was in for a huge waste of time and money. TO INFORM EVERYONE, the address is actually to his house. The pictures he has up look like an office or storefront he works out of but he works out of his home. I texted him last night saying I would meet him at 2pm today. Instead I came at 1pm thinking what's the big deal right? I arrive at the address given to me and it's a residential area. No shop to be seen. I text him confused asking where his shop is or if he is even around..I receive a call from him and he says he'll be there in 10-15 minutes. He was getting a massage...lol. So, at this point I'm already annoyed cause I thought it was an actually store where I could just drop my computer off and then leave to pick it up after it's done. A red flag should've gone off for me there and I should have left but I stick around and wait 20-25 minutes before he finally arrives. I bring my rig into his garage and tell him it has a BSOD and it's crashing constantly. He plugs it in turns it on to see the error it was giving. Literally didn't even ru any tests and says my ram or my graphics card is bad. WHICH I ALREADY KNEW. I then tell him so if that's the case I shouldn't even bother taking it here I should fix it myself since I have spare parts at home. I mean who wants to spend extra money if it's not needed? After I decide to tell him I'll try to fix it myself, he starts pressuring me and asks me: "why don't you wanna leave it here for me to fix it?" Honestly, I didn't feel comfortable anymore. His garage workstation was small, I saw no tools, and he just had a bunch of parts lying around. It was not a professional setting at all. I mean he had to throw aside parts he had lying around just to clear space for me to set my rig down.. So before I was able to take my rig and go, since I decided it would be best to take it else where, he tells me I gotta pay him for "diagnosing" my computer. At this point I am really upset, cause all he did was turn my computer on and let it crash. He didn't do anything special or work on my computer AT ALL. I agree since at this point I just want to leave and get my computer fixed. I don't have cash, and he's not able to take cards since its not an actual shop. I try to venmo him but it doesn't go through and this is where it gets heated. After several attempts it doesn't work cause my venmo account isn't linked to my checkings (changed banks recently). I assumed he felt like I wasn't going to pay so he proceeds to get in my face and call me a scammer/scam artist and says that I'm not gettting my computer back unless I pay him the 20 dollars I owe him. After that I decided I didn't even want to pay him for the time and how shitty he was treating me so I called the cops since he wasn't releasing my property to me. In between while waiting for the officer to arrive his neighbors walk by and he starts to bash me to his neighbors telling them I was trying to scam him and I'm shady this and that. The entirety of waiting for the officer he DID NOT STOP TRASH TALKING me, he even recorded me and called his friends on me when all I did was stand there and wait for the officer. The officer arrives and we both give our statements, the officer decides I have to pay him. So to be in good will I do, but I had to drive to the bank to withdraw money cause he all of a sudden didn't want to take venmo from my friend since it would be faster but instead he wanted cash only. I'm sure he did it out of spite to waste my time. I wish I recorded the events to post here and share what he really was like towards me, but I was scared and it didn't occur to me to do so. So please I warn everyone, take your business elsewhere. Daniel has horrible customer service and he definitely doesn't not know how to treat them as such.

Had an issue with a CPU installation that resulted in my PC power cycling and not working. Took it…read morehere to have someone professional look at it (before I messed something else up ). Turned out my motherboard was fried (so props to me for not messing up my new CPU after my first time trying to install a CPU). Long story short, they installed a new motherboard, new CPU, and new cooling system for me. They said it would only take a day, but instead it took about 3ish. Rather than doing a rushed job and meeting the initial estimated finish date, they needed to swap out my cooling system for a better one because it would have ruined my new CPU (Ryzen 9 5095X) due to it overheating. So I HIGHLY appreciated them going the extra mile and noticing this for me. They also tested everything before giving it back to me for QA purposes. I'd rather wait the extra few days and potentially save hundreds of dollars. They could've not done anything and had me come back later to pay for more repairs. They gave me a lot of advice as well and SHOWED me what they were doing before they did it. There was a lot of trust involved in this repair, and it paid off (pun absolutely intended). Definitely will be coming back for future upgrades. Learned a lot about computers in this process. As for the computer itself, it's running like a beast. Very powerful and very quiet surprisingly (more so than before). I wanted to wait a day after I got my computer to test out the programs I use and it's working great. When I picked up my tower, they showed me what parts were in the rig, that the display was working, and that the parts they said they were going to install were there. Kept me updated and sent me photos to show me progress. Very transparent and communicative.

The experience started off on the wrong foot when the first thing the technician asked after walking in was, "Do you have a pen and paper?" It didn't inspire much confidence or professionalism. The biggest disappointment was the cable management. It looked rushed and completely disorganized, especially considering that we had already paid before that part of the job was finished. The overall quality of the work was well below what was promised. Unfortunately, I won't be using this company again, and I can't recommend them based on my experience. Customers should proceed with caution. The photo shows how how he put 1 cable tie on the cables and said that's the best it's gonna get.
