Just rebuilt a computer using an ASRock Q1900M. The on board video died after a month. Replaced with another one and same thing. BTW, tried a known good video card both times and while in all cases the board is going about its business and booting, no video. Used a brand new Thermaltake TR2 430 Watt PS which has all kinds of over voltage and such safeguards so that can't be the problem. Is the Q1900M just a bad line of mobos?
