Your motherboard isn't supported by Windows 7 so this could be causing some issues.
Code:
P5NSLI
- Intelฎ LGA775 Platform
- Intelฎ Core2 Extreme / Core2 Duo Ready
- Intelฎ Pentiumฎ D / Pentiumฎ 4 / Celeronฎ D Ready
- Dual-channel DDR2 667/533
- NVIDIAฎ SLI Technology
- ASUS Q-Connector
- ASUS O.C. Profile Your CPU: "Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz"
According to the motherboard page, your quad core cpu isn't listed as being supported. It appears that it only support's 2 cores. This could be why only two cores are passing the tests.
IMHO, I would buy a new motherboard that supports quad core and Windows 7.
