Only 2 cores show for the I7-875K

I recently checked my processer and only 2 cores show up.

I used CPU-Z, RealTemp and Belarc advisor.

I tested my windows score and it went down quite a bit.

Any ideas what's wrong?

Here's what Belark advisor says:

Processer

2.93 gigahertz Intel Core i7 K 875

32 kilobyte primary memory cache

8192 kilobyte secondary memory cache

Reflashed the BIOS and loaded optimized defaults.

Still have only 2 cores. Nothing's been changed or moved as far as the processor.

The machine was built last year and no processer problems till now if that helps.

Resolved the problem.

Reflashed the BIOS and used optimized defaults.

Then went into msconfig and used normal startup, I had been trying to eliminate too many programs from starting at boot, I guess one of them has something to do with the processors. At the boot tab I changed the number of processers to 4 from one to help boot times and a few other things.
