I did not know it at the time but the pump had failed leading to my CPU (i9 12900k) redline for the subsequent 4 months - by the time it was May, my computer would regularly screen tear during VR, crash during games, and I was at my wit's end. I tried everything on my own until I followed up with Jose at APlus Tech Labs. He identified the issue, offered up upgrade my CPU and replace it with a new AIO Cooling system. I was very happy with the price and lead time. I wound up bringing Jose my 2nd PC as well! For this 2nd PC, the PSU or the Motherboard had gotten fried so we had both replaced in a matter of days. I really appreciate the communication and he was even able to meet me afterhours as I was unable to come during regular business hours while I had a deadline to meet to get this 2nd PC set up at home. Thank you, Jose. Appreciate what you do!~

For awhile (months) my PC has been losing video while playing games or video chatting. I swapped out parts in and out and same issue was happening. Decided to take it in to have a professional diagnose the issue. Walked in. Technician was helping someone at the time and acknowledge me. We talked about the issue I was having and provided the servicing cost which I feel was fair (~$100). Gave me a 2-day estimate for servicing. After 2 days the technician gave me a call that my PC is ready to be picked up. At the store he gone over the issue (which is an incorrectly plugged in power supply wire which I completely overlooked). PC is running very smooth. No issue ever since taking my PC in. All software running with no issue. No more power issue. No more stress. Will not hesitate to come to Kaddy's for any future PC issues.

Expert Reaction had 5-stars so I decided to give them a try. First of all, we're both in Covina and they offer free pick up and delivery. Marcus, the tech, explained that diagnostics are $99 which would be applied to any repairs. After he got started he sent me several texts to let me know what he was finding and what he would be doing. He determined that it was badly corrupted and he'd need to reformat the hard drive and reinstall Windows. (If you don't back up your files like I do everything could be gone forever.) He also checked for hardware problems even after determining that it was software just in case. End of the story is that I got a like-new PC for $170, when I feared that I was going to have to buy a new one. All companies should operate like this one does - and I would say that even if they hadn't been able to fix it.
