J-791BS is the M/B's model. It's made by J-Mark. I want to know if this is a good board to use. I tried it at 450, but the computer freezes once in awhile. Is this due to stressing the CPU, M/B, or some other component? Could it be the HDD cause my HDD is pretty slow. I have a DVD-rom and encoder kit by Creative and a Winmodem. The HDD is from NEC about 3-4 years old 1.5 gig. Any information would be appreciated.
