I just bought a p3 766 mhz motherboard/ram/cpu I installed everything and now i'm having a little problem it wont boot an os i tried 2 harddrives in this computer plus a different one and they work fine but in the p3 766 ithe hdd stops responding at a certain point (the end of the grey loading bar in win xp) I also tried win 98 on it as well. There was 3 ram sticks in it so I tried removing all of them and putting them in 1 at a time same thing. the cpu said it was running at 120oC for about 2-3 mins but after i turned the comp off put some thermal paste on the cpu it went down to 44oC I am using a basic systm hdd/floppy and the motherboard. If anyone has any ideas please reply
