I installed a video card in my computer (ATI Radeon 9200SE)but since i lost the CD i didnt installed any software. Windows recognized the video card and installed a driver. My problem is that when i play games after 40 to 60 minutes during the game the monitor goes black and a message apears (no imput signal) but the computers is still running. Any help will he appreciate.

I highly recommend that you go to A T I site and download the latest catalyst driver for your card. Using the default windows driver is okay to get you into windows but it sucks for gaming. I am actually surprised you were able to play that long! lol
the latest version is Catalyst 6.4 and that should help out. IF it keeps acting up after post back and we'll see what we can do to help.

PS: is there a way for me to disable the feature that keeps making my post damn advertising for companies that I do not know and have no desire to support!!!!!!!!!
