How do I tell if my GPU or PSU is failing? My computer randomly shuts-down whenever upscaling video on MPV and shuts down instantly when starting up furmark. My PSU has a high-pitched noise I assumed was coil-whine, and I'm getting no artifacts or screentearing. I suspect the problem is the PSU, but I really want to be sure before buying a new PSU only to find out the GPU was the problem. Any tests I can do to rule one or the other out?
