OK, so I just installed my 256 MB ATI Radeon 9250 (PCI) into my new computer. The card works fine most of the time and I've used it on another computer, but now on my new Gateway 552GE I can't play videos unless I install new drivers. This works for one boot up as long as I don't play many files. Then any of the media players I use will play about 1-2 seconds of video and stop. If I try to scroll through the video the player crashes, and if I try to close the player after it crashes, my system crashes as well. If i re-install the drivers everything is good again for a little bit... Just for a little more background my computer OS (Win XP) as well as the drivers for the card and media players are fully updated, and I don't seem to be having any hardware conflict, because everything else runs smoothly.
