reistalled windows lost 1 of my cores?

windows xp opty 170, m/b drivers cpu drivers dual core optimizer all installed. see 2 cores in device manager, in device manager instead of multiproccessor pc i get single pc how do i fix this PLEASE

 

i was able to fix it by repairing windows in case anyone else has this problem:thumbup:

 

right click on the processor in the device manager and do a driver up date, i know it sounds stupid, but it worked on all the PC at work after updating the cpu's to dual core, and you may have to do this to the cpu listed under the computer as well, and make sure if your looking at the task manager that you have one graph per core clicked. hope this helps out

 

tried that and short of screwing around with HAL and messing something up i repaired windows and that worked.

 

But as I've mentioned a few months before, repairing an installation of Windows XP will result in breaking the Windows Updates function (if you've already installed latest updates and then repaired).

 

i dont know what you are talking about i have been using xp for 7 seven years and reformatted and repaired windows probably 20 times with no problems
