Hi, Thanks for the replies. Its not a new video card and its not on-board. The motherboard is ASROCK K7S8XE 400FSB. The computer was working fine before I installed logitech quickcam. Even after installing the webcam it worked fine for a few days. But now even if I don't install it, the computer doesn't work!! Thanks again. mjng

Hi, My computer works fine in safe mode and if I don't install the display driver for the video card (NVIDIA GeForce4 MX440 with AGP8X). After I install the driver (downloaded from nVidia web site or from the cd I got from my computer hardware provider), I face the following problems: - the screen goes black, comes back, goes back again 3-4 times very frequently - screen gets locked occasionly, needs to be rebooted - if I try to use my web camera (logiteck quickcam), the system hangs every time I try it. - sometimes computer reboots while booting up. The hardware is fine, has been tested by the hardware provider. Therefore it seems to me to be some driver software's problem. I have this problem with both windows xp and win 2000. CPU is AMD Athlon. Please help me out with this problem. I don't have any clue what to do!! Thanks in advance mjng
