All of a sudden this evening I got this on my laptop- pic should be attached. I've done a diagnostics test and it says hardware error. I dont imagine anyone can tell me what to do but if you do have any ideas that'd be great. I was planning on taking it back to PC World tomorrow cos I'm hoping laptops have 12 month warranty but can't find the receiptthe box says PC world on it so I'm hoping that proves it enough. If not going to have to call Dell yet again! I've had nothing but problems with it
