Hi all, I have a problem with a machine at work. When i switch it on it goes through the boot screen fine and as soon as it leaves the boot screen and goes onto the log in screen the whole screen becomes corrupt(Broken graphics, missing gaps unreadable). I have tried the graphics card, memory and the psu but the problems is still there. Booting in safe mode is fine, just as soon as it hits super vga mode is does not want to play. Any ideas?
