After upgrading my processor from a duel core to a quad core the device manager will not recognize the correct proccsor, i researched the microsoft knowledgebase and found that the registry still thinks i have the old processor installed, so i went by the instructions and removed each processor and rebooted, now all four cores are listed as unknown device. i read further on that i could reinstall the drivers and point to intell processor (which i did ) and reinstalled, I still can see all four cores listed as unknown device. any new suggestions, all four cores work find and the processsor speed is identiied in other areas correctly and microsoft says its just cosmetic, but i want it to read correctly. thanks in advance for any help

Reinstall drivers of your chipset. You can find them on the cdrom of your motherboard.

it can be you need to flash your bios, before the motherboard identifies the cpu coorrect.
check your motherboard supplier site for it, since you did not post it, i cannot do it for you..

I have the newest chipset drivers and the newest bios for my motherboard. the motherboard identifies the correct cpu so i know that isnt the issue. as i stated before, microsoft has identified this as a known issue regarding the registry not reidentifiying the processor.

yes cpuiz identifies them correctly, its microsoft vista registery, and i did what microsoft asked me to do. they say its cosmetic and they are aware but it should be fixable.
