Well, I set the HTT on my A64 3200+ to 220 and apparently my system didn't like it. Prime95 ran stable for 44 hours but I couldn't run 3DMark03 even once without my system hanging or getting an error that said I had a corrupt texture file. I set my HTT back to stock (200) but now I am noticing that some programs are crashing and giving me errors at random. When I ran UT2K4 it gave me some odd runtime error. This only has happened once so far. Also Mozilla has been crashing at random intervals and giving me the Microsoft Error Reporting box. MainConcept MPEG encoder also crashed once when I was setting up an MPEG to encode. None of this stuff had ever happened before I set the HTT to 220. So, what are the odds that my bad OC caused this and if it did, what do I need to do to rememdy the situation. Also as the topic says, does this mean my OS is corrupt?
