please ignore my sig as it's a different pc.
yes,I'm also confused.
with normal pcie card inserted pc does not boot.
with matrox card inserted pc boots and works ok.
yes there is bios beeps without a card in.
the matrox card is from a server pc.
they are more for 2d rather than 3d,hence the lag.
even with matrox drivers installed it still lags.
it must be something within the pcie slots on the motherboard that has broken or something other on the motherboard?
