MY SETUP:
i7 3770K @ 4.5GHZ
GTX 670
H80i Cooler
MSI Z77A-GD65
Corsair TX750 Power Supply
OCZ Vertex Solid State Drive
Windows 8


Okay, so here's the deal.

My rig has been running smoothly for about five years. Recently my monitors would just shut off and would not get a signal from from my graphics card. They restarted and got a signal but then I saw artifacts in game so I thought of this as a sign that my card was dying.

I ordered a new card (GTX 1070) but the problem persisted. My monitors would randomly shut off and sometimes there would be a sound that was stuck replaying from what I was doing in the OS. Other times the entire system will shut off and try to reboot but only boot up for a few seconds before shutting down and trying to restart again. The error message said that it was a graphics issue so I have used DDU and updated drivers a million times but no success. Might be important to note that I have not had any artifacts at all with the GX 1070, that issue only happened with the old card but the crashing still seems to continue.

At this point, any idea what might be causing the problem? CPU, GPU temps are fine even while gaming. I have tried REGEDIT TrDelay fix, made sure my drivers are up to date and set every power management mode to performance. Any help would be appreciated <3

First test your system without the overclock. Your system seems to have stability issues and the most likely suspect is the PSU but you shouldn't also rule out the motherboard just yet. When a system is failing to start/restart or is having random restarts means that the PSU is most likely failing but as I said you can't be 100% certain until you test your system with another PSU. Finally a PSU that is over 5 years old is not generally considered to be a reliable unit anymore excluding those expensive high end PSUs that also have a 7+ year warranty. So I'd say it's 75% PSU, 20% motherboard and 5% something else.

It may be the PSU, especially if it is over 5 years old. If you can borrow another PSU from a friend and test it with your system you'll know for sure if your current PSU has gone bad. You should also test your system without the overclock and see what happens. If the PSU is OK then you should turn your attention to the motherboard.

The artifacts were a sign of a bad GPU but all the other issues seem power or driver related and since we can take drivers out of the equation all that remains is the PSU and maybe the motherboard.

I'm inclined to agree. When it crashes and tries to restart but fails a few times, is that a sign of PSU failure? I would just like to be sure because I don't have a friend whose PSU I can borrow so I'll probably just end up ordering a new one. Is that specific symptom more likely to be a PSU failure or Mobo failure?
