So i'm building a system with a Biostar GeForce 6100 AM2, Athlon 64 3500+, and WD 250gig SATAII HDD. The system boots fine, I load windows fine, the only problem is that the hard drive is half as big as it should be. Something is only seeing a 120gig hard drive instead of a 250gig. I was thinking perhaps BIOS needs to be updated, but the board model is less than a year old. Thoughts?
