Only 1 Core being used, HELP?

Hello,

I am only seeing one core of my Intel e8400 cpu (Dual Core 3ghz) in windows, im using a Asrock p45r2000 motherboard. I have tried Windows XP, XP64, and 7, but no change.

I have tried updating my bios but no change, It has worked before, but just stopped one day.

CPUZ and CPU Benchmark 2, show only one core running the other is disabled, when they previously showed both running ok.

Im sure it was a case of changing a Bios setting but I cannot remember which one it was!

Please Help as under much stress due to deadline, Would doing a fresh install of OS work?

Thanks, Matt

Well, in my experience installing, that thing usually happens when you put an old OS installation into a new hardware. (Like putting a dual core processor in an installation where it's only a single core previously) So try it.

Question one in the bios does it show the correct CPU being installed?

Question 2 does CPU-Z show it as an E8400?

Go to Run by hitting the start ket and r or just open up run from accesories open up msconfig. Under boot tab click Advanced Options you will see number of processors up top check the box and put it to 2.hit ok apply and reboot.

Hi Thanks for the replys, have done fresh install, no difference. Have tried the procesor removal, no joy either :o (

CPUZ does show it as an E8400 with only one core, it also shows up in the BIOS correctly. When I tried msconfig/advanced, I only have the option of 1 in the drop down box...

Its making me think its got to be something to do with the Bios setup?
