I am running Windows XP which I have recently downgraded from Windows Vista. I have installed it from my backup disk and everything went normal. I didn't had any problem while working on Office application or listening music. The problem first occurred when I tried to start some games. I noticed some glitches in the graphics during the game play. I tried to figure out things but didn't found the actual cause of the problem. It didn't appeared when I was running Windows Vista or even when I was on Windows XP itself before few months back. I then tried to see if there are any drivers that are clashing with my onboard graphics but didn't found anything unusual. What is the problem with my graphics suddenly and how can I solve this problem? Is there any solution to this graphics glitch? My system specs include Intel mobile 945GM Express chipset, 2 GB ram, no video card, 160 GB hard disk. This is a laptop.
