I have a Pentium III 933 mHz chip with a 133 FSB. A while back it started to spontaneously restart the whole computer from the Windows XP login screen just as if I pressed the reset button. It would do this several times (up to 10 or 20 times) then finally boot into Windows. After a few months of this, it gave me a blue screen and refused to boot up. I bought a second hard drive and reinstalled windows XP and it cured the problem for about a month. Then it started the whole cycle over again. The only way I have found around this is to go into the BIOS and set the processoer speed lower. I first went to 700 mHz and now I am set at 466mHz with a 66mhz FSB. Can anyone tell me what is going on, and more importantly, how can I get my 933mHz/133FSB back? Is it the chip and do I need a new one? (Someone iI know suggested that.) Thanks a lot for any help at all.
