I recently built a PC and it worked for 3 weeks. Now it refuses to turn on.

Here is the Pc:

The build went well and I downloaded windows+ all drivers. It worked for 3 weeks but I had a IT buddy come down and take a look at the build to better optimize everything. On HWInfo it said I had a hardware issue. Specifically: CPU Cache L0 Error in hwinfo64. I googled the issue and it said that it's usually related to overclocking. That night I left my computer on when I went to bed as I was downloading a large game. The next day, when I tried to turn on the computer, it was dead. Nothing turns on. No lights, no fans, no noise, etc. It's completely dead.

I thought it was PSU so I bought a new one and installed it. Still absolutely nothing. I bought a new motherboard and still nothing. My friend said it would be CPU so I went out and bought another one at bestbuy. I was hesitant to open it as I wondered if it could be something else and cant afford to drop anymore cash into this thing. The computer worked for 3 weeks and then just stopped working overnight when I was downloading a game.

To my suprise, when I removed my GPU my PC turned on. I examined the GPU and there dosent seem to be any damage. The GPU seemed to work fine for 3 weeks. I'm wondering if my GPU is dead or if my PSU is the problem. I'm assuming dead GPu as the PC worked for a few weeks.

I am wondering, is there any compatibility issues with the peices I selected? Is it possible I fried my GPU? I didint touch anything in terms of overclocking.

My friend said that my GPU takes 12V power and it is an older model that isn't made for the new ATX 3 stuff. With the adapter, it shouldn't matter, but it's possible the adapter is crap or damaged. He said i can verify this with an ATX 3.0 PSU. Is it better to send back the GPU as it's on warranty or buy the other PSU and dump more money into this thing


Any insight would be greatly appreciated!

By any chance did you flash the BIOS to the latest version after you'd gotten the system up and running? Your GPU is the most power hungry component in your build, if removing that from the system allows the system to power up would mean either you have an issue with your GPU, or you're having a power related.

Might want to try and drop the GPU onto a donor system with a 1KW unit and see if the issue persists. If your GPU is the issue, then it won't power up on your donor PC. It could also be a short on the GPU.

Yes I did update the BIOS to the latest version when the computer was up and running. What is a donor system? Does that mean just another computer? If so, I don't really have access to another system and definitely not one with a 1k PSU. Is there no other way to test the GPU? I find it weird that it worked for a month and then it died overnight. Thanks for taking the time to respond to this buddy!
