You might remember a while ago that I posted a thread asking for help building a computer. This is being posted from that computer, and I love it. However, I am having some on-and-off stability issues. At one point it would lock randomly and frequently, and also once gave a "page fault in nonpage area" bluescreen; the latter only happened once and the lockups stopped after I reversed a vcore tweak I'd made in an attempt to keep heat down. However just now I got a "kernel mode heap corruption" bluescreen which required a restart; from what I've seen on a search that may be related to geForce graphics drivers? However the guy who reported that had it happen way more often than I did. Any ideas what's going on here?
