Computer stutters and crashes.

Sort of a complex situation going on here.


About a month ago, GPU failed or at least I think it did (card was a GTX 770). Crashed the computer with artifacting and all kinds of crazy visual gitching. Restarting with that same card resulted in the computer BSODing after 10-15 minutes of stuttering from very light use (computer was more or less unusable). Going into safe mode was the only way that I could run the machine with that card still inside of it. Tried everything from using ddu to remove the GPU drivers/installing older/newer ones, running linux/benchmarks/virus scans to pulling apart the computer and checking for physical damage (even reinstalling windows a couple times). In the end, I determined that either my PSU was failing and it wasn't giving enough power to the GPU during high loads or the GPU was fried (or some combination of both). I took the card out and replaced it with an old gtx 560ti that I had lying around and the machine seemed to be relatively stable. The computer felt slower then it should be but at least there were no more BSOD errors.


I do a lot of video editing, GPU intensive computations and gaming so naturally I determined that I absolutely needed to get a new GPU. I got the GPU just yesterday (Radeon Rx 590). I put the card in and everything seemed about the same. About 12 hours into working on the machine I started noticing small stutters during normal operation (web browsing, word processing etc), programs would randomly hang before resuming operation. Running games seemed to work fine; was able to play GPU intensive games without issue (no unexpected FPS drops) until about an hour ago when one game froze. It threw up a BSOD and from what I could gather before it restarted, it seemed like a GPU driver malfunction. I can't know for sure what the BSOD error codes were for this crash because for some reason the computer didn't make a dump file.

Basically at this point, I am pretty confident that I have a hardware problem but I need to determine what piece of hardware is malfunctioning. I am suspecting the PSU but diagnosing a PSU failure is pretty complex and not easily done via software means (don't have a multimeter either). It is of course possible that the problem could be something like the memory or the motherboard but again, I am having trouble finding out exactly whats going on. Putting a higher power GPU into the machine seems to initiate the problems (or at least make them bad enough to cause a failure). I guess its possible that this is just a driver issue from putting the AMD card in my machine but that feels like too much of a coincidence at this point.


I need to figure this out fairly quickly so I can decide whether or not I should return this GPU. If it is the PSU or the Mobo, then its possible that the older gtx 770 is still in workable condition. I do have plans to replace the computer some time soon but I currently am short on cash and simply can't swing it just yet, I also happen to be a software developer so I would rather not lose my only machine.


Does any one have any constructive feedback or suggestions?
