Hello, I have disabled cores in my i7 cpu (running on an Asus p6X58D with Win7) so I could play an older PC game. I did this in the bios, selecting 1 core rather than 2 or all. So far so good.

But, game finished, I went back into the bios and selected all cores. No probs. But running core temp showed only 1 core. Msconfig-boot-adv options only shows 1 processor. But device manager shows all 8 cores present.

I have updated to latest bios, uninstalled all cores in dev manager, to reinstall at boot, but still I can see only 1 core present and working.

Is there a registry setting that I could check? I seem to have tried most of the things suggested in forums.

Many thanks!

Just downloaded cpu-z - shows 1 core, 1 thread only. Device manager still shows 8 cores.

PS - as I have flashed the bios to update it, I didnt bother resetting the cmos. Do I still need to do that?
