LOL your CPU-z Shows you have 1 Core?! Something is wrong buddy. It could be the motherboard and the bios Settings or that your Processor is messed up or you might Try Intel's website and download your chipset drivers. I hope your able to fix it.
I still chose AMD for Gaming. Now that ICore 7 is out I think Intel has got a sale from me. Still going to use Nvidia for my GPU's.
If you've installed the pentiumD and replaced an older single-core model, you will need to re-install windows. You are currently using the single-thread kernel. Reinstalling windows will allow you to use the multi-processor drivers.
