March 31, 200620 yr After bad overclock, my system hangs and craches few times and there were few blue screens, I had to go for Last Known Good Configuration method for boot, after that I lost second core, Windows XP SP1, now sees only 1 core on my Opteron 170. Is there a way this can be fixed without windows reinstall? Thanks in advice
March 31, 200620 yr well are you stilll in last known good config?if you are then i suggest you reboot to normal mode.if yyou are in normaly try removeing the acpi uniprocesor system driver, that should make windows detect the dual core.............

I have ACPI Multiprocesor PC. I fixed it, what I did is I just clicked update driver on ACPI Multiprocesor PC, and rebooted. Second core after reboot appered. Thanks
March 31, 200620 yr Interesting problem. Glad it got fixed though. May I ask why you are still using SP1 instead of SP2?
April 3, 200620 yr Author Interesting problem. Glad it got fixed though. May I ask why you are still using SP1 instead of SP2?No special reason, I got attached with SP1 LOL I have many things istalled on my machine, as long as work fine, I will not install SP2. In case of some problem, I will do a clean install SP2. Thanks
