Hey yinz guys - I'm a seasoned veteran of most hardware troubleshooting by now but I come to you humbly seeking guidance. Here's the deal:
System was built very cheaply for a friend with, at the time, the amd 5600k so he could use the onboard gpu until someone gave him an Nvidia 560TI. It did it's job for some time until recently when i started blackscreening on him.
I had to go into the bios with the PCI-e slot empty and the card unpowered in order to get it to boot into windows. Once there, it seems stable and fine. So I put the card back in, plug the display adapter back in, and black screen (with POST beep). So I unplug it again, head back into the bios, and disable the integrated graphics solution. I then reseat the card, power it up, and it POSTs and the monitor comes on.
That's all well and good except now I am getting green artifacts when the windows screen is loading (windows 8, doubt it matters here), and then it wants to do a system restore. After cancelling out of the restore, occasionally I can get it to go to the login screen and proceed, but there is non-moving artifacts still present on the desktop that are not there with the integrated solution.
Now, the PSU is a cheap Rosewill, but there is next to nothing in this system drawing power.
Thoughts:
1. GPU has **** the bed (probs, everything else when the card is unpowered seems stable and displays fine)
2. PCI-e slot has **** the bed
3. PSU is no longer supplying adequate power (450w rosewill)
4. the (2) 6 pin molex to the 560ti are damaged or otherwise not supplying appropriate power.
Diagnostic options:
If I can get the damned thing stable in windows with the discreet gpu in, I could potentially run some software (cpu-z maybe?) to verify the voltage to the gpu. I don't want to put the potentially damaged gpu into my system, nor do I want to put my 1080 into a potentially volatile pci-e slot. Anything else I might be missing to logically want to include in a diagnostic of this POS ? Thanks!
