You can go to a good comp store like Micro Center or maybe even Best Buy and purchase a power supply tester, you unplug the main harness from the MB and plug it into the tester, and it will let you know if there are problems with it. I have one, I think I paid maybe $10 for it, but that was probably at least 7 years ago.I would welcome BSOD at least I know I could do something. But a black-screen of nothingness horrible.
