My computer had a couple of upgrades on my sis 661-mx, new ram, upgraded to xp pro, changed celeron d 325 to a pentium 4 prescott with HT. all was going fine till I installed some spyware detectors and they told me to restart my system. Well after I did it ran fine, the next morning my blower was making noise, toke it out and turned the computer on, the bios that says the energy star such and such then it goes to Detecting Pentium Processor 2.6 and then nothing goes no further, nothing works, it just stops. now I tried the power supply, took out the sound blaster, the agp card, disconected the hardrives and the same, took out each stick of ram, no beeps just nothing after detecting cpu, I even tried puttin the old celeron back, detects that and then also nothing, do you think the motherboard just died. I ordered a new one from new egg an biostar type like my sis, just a lil different.
