I build two of the same computer about two weeks ago, hardly been on the internet but for the most part they have been good; I build the computers the same exact way yet one of the two is getting tons of errors. I get NSIS errors on everything I download telling me "it's corrupt", when I play the slightest game the display driver crashes and tells me it has recovered. I also get BSOD's and I would love to post them here but, their corrupt too. The CPU is running very hot according to HWMonitor (like 55 degrees Celsius idling). I'm not new to computers and I can't tell if it's either the power supply, or CPU (don't think it's HDD, CHKDSK said it was OK). The PSU is just a PSU that was with the case I bought and I had to get it because I had a $400 budget. Can I get your guys' knowledge to help me out please? Thanks.

Some cheap PSU that came with the case.
