Just turned on my PC and I have lines going down the screen each made of blocks of colour and 3D is covered in blocks too, I assume this means I'm screwed? 
If so can anyone recommend a replacement for a 9800pro, problem I have is the replacement cannot be any longer or it wont fit in the case :/ I'm planning on a whole new computer in the new year anyway but need tiding over till then.
edit: got a screenshot:
