Im using an old hp d325 computer with mame, its an amd athlon xp 2800 with 512 ram and a nvidia geforcefx 4 128ram, work ok with most games but i do have a problem, if i try to use d3d for the video render in mame, everytime i exit a game i get a scramble picture and i have to restart my pc, but if i use direct draw i never experience that problem, i fell that most games run better on d3d but due to the problem i have to run them in directdraw. I have to mention that before i was using a petium 4 pc with the same video card and never had that problem, so i guess it must be somenthing to do with the d325 motherboard im using, thanks in advance for any help.
