Windows 7: Dual Core Processor detected as 1 core

Dual Core Processor detected as 1 core

Firstly, in task manager, there is only one core recognised (one cpu graph). I have no option to select "one graph, multiple cpus".

Secondly, in device manager, there is only 1 core with no option to select 2 or box for detect HAL.

Lastly BIOS doesn't detect more then 1.

I have processor box unchecked and have uninstalled my CPU from device manager in hopes a restard would re-detect it. I have also updated my mobo & vid card drivers from the site and updated my bios to the latest.

I just bought COD: Black Ops for $60 and it requires a dual core processor to play it, anything else I can try short of re-installing windows?

just checking that you realise dual core will only show as single cpu?

If you mean within Windows, that's not true.

For example: Core I7. Four real cores, plus hyperthreading. Windows sees it as 8 processors, and shows 8 CPU Usage History plots in Device Manager.

It's possible to manually set a different HAL in older versions of Windows, but I don't know how to do it in Windows 7. Perhaps a repair install (upgrade in place) would autodetect the CPU properly, while maintaining most of your settings and installed programs. A clean install may be likelier to work.

Good luck.

so are you saying my pc may be actually running both cores but only shows as one?
after much researching I determined that the problems I was having with Black Ops was caused by not having a dual-core minimum. But if it is running both cores then there should be no issue....I'm stumped.

What do you see if you run CPU-Z or a CPU gadget ?

Try:
Task Manager\Performance tab: Click Menu item: View\CPU History\ One graph per CPU.

Whoops, should have read your OP more carefully. Given that it doesn't show in the BIOS, the task manager workaround is irrelevant. Can you give us a little more history? Is this a new install, new CPU? Are you running the latest bios? Yes, I see that you are.

well to be honest with you I had the comp built and assembled at Memory Express and I couldn't tell you if it ever ran on both cores. I did recently install windows 7 on it, but Black Ops is the only game I am having problems with and I play higher end games then that.
