I have a WinXP Pro PC running an AMD 4200+ X2 S939 CPU. I recently noticed that when running Task Manager only one core graph is showing. I ran CPUID & PC Wizard 2008 and both programs say I have only ONE core. PC Wizard says 2 cores w/ only one core enabled!
I checked Device Manager and Processor shows only one instance. I updated the driver thru the Device Manager and rebooted and everything looked back to normal...Two cores.
However after a later reboot my PC is back to only one core running. I have rerun driver update but now it says driver is latest. Also ran BIOS update, downloaded & installed various updates from AMD & MS, Googled for several hrs...But I can't find a solution. Is it hardware or Windows? I am totally stumped.
