multi core cpu registering as single core.

D007 · Aug 26, 2009

Anyone ever run into this issue?
e6400 conroe on windows xp.
all of a sudden it's calling it out as a single core in task manager.
Can't set affinity or anything.
Only has one cpu graph in the performance tab as well.
but it shows two cores in device manager.
Evga offered pretty much no advice on the subject.
But I'm really not sure if it's the processor or the mobo causing the issue.

I'm leaning toward the processor though, since it's always overclocked like crap.

so far I have tried uninstalling them in device manager and letting them try to reload apon reboot.
I have reformatted my pc and done a clean OS install.
I have reset cmos by taking out the battery and rebooting.
I have flashed bios to the most recent.

any advice is always welcome.. thanks again XD..

likely, you need a new motherboard or new CPU.

You'll have to get access to a spare CPU or mobo in order to test which is playing up.

Try cleaning the pads on the bottom of the CPU?

I only recently got this mobo from these forums actually..
Got it because I was having strange issues on the other mobo..
had the same processor on the other mobo as well.

I haven't tried cleaning the pads on the bottom of the cpu though.
Hasn't even been in there a year yet.

But I'm leaning towards it being a cpu issue since problems followed me from the other mobo.
the strange ethernet issues where my network adapter suddenly disappears and I have to reset cmos to get it to reappear followed me.
