Computer has been restarting suddenly, I noticed it happen once a few months ago but didn't think anything of it. It is doing it very frequently now to the point where I cannot do anything. Tried to do some self diagnosing and when I disconnect my graphics card completely it stops doing it. Would this more than likely be a bad PSU instead of GPU? What kind of tests can I do without having a second PC to eliminate one or the other?
