Rebuilt a PC, where are my 3 other cores? :(

I finally got my PC back up and running after swapping out the m/b. I get Windows installed and everything, then check the task manager and see this.



I'm seeing only one core there, and not 4 like I should be. I checked the Bios and the other 3 were enabled. I'm getting sick of this thing.

Any ideas?

Oh, Quad Core 9550 and an EVGA 790i SLI FTW motherboard in case you were wondering.

View>CPU History>One Graph Per CPU

Nope. That's the only option.

Hmm, interesting, try running DxDiag to make sure that it is listing your CPU as 4 CPUs, if it isnt there is a bad setting somewhere or there is a physical issue.

but a possible fix is to install the mb drivers . Again if you already have

and if that doesnt work reinstall windows and then reinstall the mb drivers

Activate all 4 cores in the BIOS if thats an option... i know my 750i has that option.
