Hi, my display suddently became garbled last night. The desktop became a chequed pattern of horizontal purple lines. And each new window had the same effect. This is Windows XP on a Gigabyte MB with a Radeon 9700 Pro into an Iiyama Pro 510 21" monitor. I tried a different monitor - same problem. I tried a different graphics card - a Radeon 9000 - similar problem but not as drastic. Just the odd desktop icon has a purple band through it. Is my motherboard buggered?
