I just recently replaced my hard drive...i low level formatted and installed windows xp on it..I have a PCChips Mobo M825G I have 1 gb of ram. after just recently downloading all the updated drivers and without installing any other programs, I am noticing the computer locking up. I have to manual reset it each time. Does this have to do with cooling by chance? I checked the bios and the mobo is overclocked at 166mhz running as athlon mp. the cpu temp is 56C and the system temp is 46C . I only have 1 case fan. Is this about normal for this type of computer? I can run the processor as 133mhz or even 100mhz dont know if this could be a problem either.....
