Garbled display problem

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?

Update to this : If I push dhow on my graphics card, the patterns on the display change. (The motherboard does flex slightly). Feels like a dry joint on the motherboard. Am I guessing correctly?

Update #2 : On further investiagtion, it looks like the second (lower spec) graphics card 'inherited' the broken icons when it was installed, and it wasn't until after re-installing the Radeon drivers that these icons were restored.

And the system is working fine with the old graphics card in it.

So it looks like it is the Radeon 9700 pro. Which is painful since it was imported from the US and then I installed a Zalman cooler on it.

Whoosh one very expensive card goes in the bin and out goes £300 on a new 9800XT.

If you had to reinstall the driver to make the 9000 work properly then perhaps reinstalling the 9700 with a clean driver might help?

Got to be worth a try before you bin it!

I had trouble with a 9500 which used to have strange colour effects when it got really hot, binned that in the end.:rolleyes:

I'd recomend getting the 9800pro for around £130 instead. It's a bit slower than the xt (about 5-10%) but you'll get it for less than half the price:)

Thanks guys, yep I think the pro for Overclockers.co.uk for £132.
I have the 9700 another try but with no joy.
