Ya my theory was correct, PSU was old and wasn't clean enough power or delivering enough, sorry for being so dickish but like I said I wanted theories I couldn't think of myself, I had already ordered a new PSU, 2 days before I even made this post, I was looking for possible motherboard or GPU issues that other people had knowledge of. O ya installed new PSU today, it's all working good, my guess is that the 12v rail the 24 pin was running off of was just starting to hurt or I was exceeding the power of the rail.
