TX750W 12v Ripple?

[EchoAlpha]

Hi guys,

For the past couple of months, my PC has been crashing to a black screen every couple of weeks. There doesn't seem to be a particular program or action that causes the crash, it just happens randomly. The stop error in the event viewer just lists it as a general hardware error.

Last week, I attempted to boot my PC and was greeted with this: http://imgur.com/8esbV.jpg The computer just hung at that screen, so I turned it off and on again. This time, I got the same image and hanging, but only the white squares were there. I restarted it a third time and it booted normally. The squares only appeared at the welcome screen, the BIOS splash and that windows screen immediately prior to the starting windows screen are fine.

Here's what I've already tried:

 

• Memtest 86+ (No problems found)
  
• Scan drive for errors (No problems)
  
• Update drivers and BIOS
  
• Run benchmarks to stress the CPU and GPU (No crashes)
  

 

I suspect the video card is at fault, but EVGA tech support thinks it might be a ripple in the 12V rail. Unfortunately, I do not have another power supply or video card to try out either theory.

After looking at that picture I would suspect that the graphics card is more likely, but if the PSU is not providing clean power to the graphics card then its possible that the PSU could be the root cause. The only way to know for sure would be to test the card or the PSU in a different system and see which component gives you the same problems in a different system.

 

If you would like to try replacing the PSU then please Request an RMA.

Artifacts from an overheating or faulty video card are usually more sporadic but it may still be a video card at fault.
