Whenever i try to play any game (cs, delta force, AOM titans, Generals) my computer locks up or crashes with the error Diver_not_less_or_equal 0x0000000D1 iv tried formating, installing DX9b DX8 the new nvidia drivers but nothing works, SOF2 DH worked which is wired cos its more graphically intensive than AOM titans or CS is there some way i could test the ram or my video card? Thanks in advance

Have you try to download the latest driver from Nvidia? Download the 53.03 driver from this link below and see if it helps. http://www.nvidia.com/content/drivers/drivers.asp If you have problem with the games you play, you should try to do some benchmark on it and see if it do the samething. Try out 3DMark 2001 SE or 3DMark 2003 and you can download at this website. http://www.futuremark.com If your system does not run benchmark, I would open up your case and ensure everything plug in properly. Sometimes your video card may require an external power source in order to make it work, if you forgot to do that, it will have problems. I'm not sure if your Geforce FX 5200 needs an external power source but its a good thing to check. If all of these approach doesn't work, I would go to the store if exchange the card if possible or go to the store and grab a video card and try it out. If your friend has a spare, ask him for it.
