My problem is i have just purchased and installed a Core 2 Quad q6600 and windows is only showing 2 Cores, My motherboard is asrock P41C-DE I dont need to update bios.

Device manager shows all 4 cores installed correctly, Task manager shows only 2 cores. the weird thing is core temp shows 2 core and says I have a Core 2 Duo e6400 which is what i had previously.

Do you think i need to reinstall windows or something?

Pls Help!!!

You didn't reinstall after a cpu swapout? I think that maybe your issue tbh,
save all beloved files and make sure you have drivers for everything and your winkey, then fresh install for the new chip,

Try pulling your cmos battery for 5 minutes and put it back in.

It shoudnt be necessary to reinstal windows at all. Resetting your BIOS by removing power then the CMOS battery, press power button and then putting it back should do the trick. Then you would not need to wait. But its fixed so oh well.

Well I tried removing CMOS battery and power, but it still showed up as e6600 lol, but yeah its fixed now anyways.
