BSODs on budget made computer

[tweak13]

Ok I'm really regretting doing this family a favor, basically they had someone buy a bunch of very cheap computer parts with the exception of a few that I picked out after the fact. I assembled it and It's been getting some BSODs since. Here's the story, It seems to work fine for the most part, it might get a bsod after 3, 4, 8 hours after its been on so it's very random. BUT I can get it to blue screen everytime doing this. It's hooked up to a 32" inch LCD TV through HDMI cable, if I cycle through the TV inputs back to the computers input on the TV, BAM - blue screens everytime. I've ran MemTest86 for hours, prime95, ordered a PSU tester that should be here very soon, updated an insane amount of drivers to the point that everything is up to date, even bios. Temps all look fine, voltages...I'm really out of ideas and narrowing it down to the MOBO or Graphics card, specs are below.
