New PC Build Loses Display After 3-5 Minutes

I recently built my first gaming PC with a lot of research done here. When trying to install Windows 8, the computer would lose display after about five minutes, but all of the fans would continue running. I tried moving my gpu to the 4x PCI slot which worked long enough to install Windows 8 but after about an evening of constantly restarting the computer after freezing during updates, the computer would not display anything, even from the 4x PCI slot. Then I tried using an old graphics card which produced the same problems. Thinking it was a motherboard issue I ordered another motherboard. Last night I hooked up the new board and found I had the same problem with both gpus.

I am new at this and a little lost. Any help would be greatly appreciated!

PowerColor tends to cheap out on parts in their components and I would have said that it would be your issue there, but since it didn't work with an old GPU that strikes me funny. I also have the same exact motherboard as you and it works fine with my 6350 and GTX 770. I think that it most likely is a CPU issue, make sure when you applied thermal paste it didn't run off of the sides of the CPU and onto the mobo itself, make sure it is seated properly, and if you are certain you did it all right, then I think your CPU might be defective.

Thank you apcs13.

I double checked the thermal paste, reapplied and tried again. I still have the same problem. I will try replacing the cpu.

Would it be possible that the issue is the power supply not giving things enough power? Like I said, I'm very new to this and kind of grasping at straws...

No, that power supply should be giving your system enough power for sure, and the problems you seem to be having do not seem to be ones that would correlate to one of where a system is not receiving enough power. It seems more like there is either an issue with a core component (GPU, motherboard, or CPU) and since you tried a previously working GPU and got another motherboard, it just seems to me that you could have a problematic CPU.

Well the cpu is still under warranty, so I will probably try replacing that as well. Thanks again for your response.

I was chatting with the technician at a local shop and he suggested I didn't have enough power in my machine. I know you said I should have enough power but would it be worth it to move up to a 700 watt just to be safe.

So I sent the CPU back to Newegg (after paying the $15 shipping) and Newegg (two weeks later) sent me an email claiming "The CPU was received with apparent end-user caused physical damage to the CPU contact pins." Not sure how (if) that came into being, I was very careful with the CPU, not exerting any downward pressure; etc. That said this is my first build and mistakes happen. Needless to say I probably won't be using Newegg anymore.

Anyhow, thanks for your help, will update when I get it working!
