Hi. I have just upgraded to an Asus P5P800 SE motherboard. I am having no problems installing windows xp or any other software except the Intel INF chipset update and windows SP2. When I install either of them my display becomes corrupted with horizontal bars with multicoloured pixellation. I can still see some of the desktop in the gaps between the corrupt sections of desktop and I can even restore the system to an earlier state by carefully using the corrupted desktop. However, I have no idea what is causing the problem. Can anyone give me any advice about the problem?
