I have a celeron 466 in this machine with an asus p3b-f for the mobo... I have been having random restarts that have been taking place and then it will hang when trying to load up anything. Eventually after like 10 restarts it will finally come up in my bios or whatever and either say that my CPU speed is wrong or my CPU Bus/PCI Freq. is not right. I have the CPU speed set on manual and the Bus PCI Freq. is at 66.8/33.40. I have no clue why its doing this... can someone help me out?
