I am running XP Media edition 2005 with Viewsonic VX715. AMD 3800 One Gig of memory.
On three occasions recently my display has reverted to a very strange picture the whole frame is covered with very fine columns of lines. The computer is still working and sound is ok. However,since I can not see what is behind this pattern nothing can be selected with the mouse to try and see what is causing the problem. By using the remote I was able to get the tool bar and then able to select a prog.and this was displayed on top of the pattern. A reboot restarts with a perfect display and no other problems,and I can not make the problem happen, it seems to be random. Any ideas please?
Agree with Woodchip. I had a very similar effect. Also check the add / remove programs in control pannel. You may as I did a while ago have two sets of drivers installed for your graphics card. If this is the case, uninstall all drivers for you card and install the latest ones.
