When I reboot my system, the computer locks up. For some reason, it stops just before counting the memory on reboot. I keep turning off, and restarting the computer until it finally clears, and proceeds to my desktop (about 2 - 10x). Any idea what this could be? hardware or software issue? Should I try running a mem test? I know the memory is good, because Corsair sent me a second set...the first set was bad.
