opposite from u, all the computer I built uses MSI mainboards. Never gave me any trouble before. The current 1 i'm using now is also MSI, been running it 24/7 since June 2002. RAM wise, however, i never put 4 sticks before, at most 3.
WinXP, very stable. I don't have to restart unless after installing some system apps. Agree that computers are not for computer dummies.
