When I boot up from cold the computer states that it is unable to read video card. It lets me past the prompt by pressing OK. Then when I go into control panel To check the hardware it shows that I have the ASUS 9250 as a video driver and that its working OK. When I put it in I zeroed the on board graphics memory to '0'. My brother says I should remove the jumper for the on board video. I just put a 2.53 P4 in and added 512 of ram to a total of 1 gig This one flight combat simulater I play(Janes ww2 squadron), although it plays a lot better, still has some lag/jerky graphics when the play gets busy with lots of planes/ detail. Any Ideas.
