I have seen a number of folk posting here , with this model, who have experienced graphics issues. I am hoping you can advise us also.
The machine was fine yesterday. Today on boot, right from boot, the display is corrupted. No beeps, just garbled screen, double images, broken and checkerboard appearance. In Windows, if you click on a line of type, it will become readable, but the machine is not usable for practical purposes. We attached it to an external monitor and that also showed a corrupt screen.
We think we are going to have to put a new motherboard in - but first need to check if there is any explanation other than a faulty graphics chip. Can you help please? We are in UK, the machine is out of warranty.
