My computer gets this strange colour mash-up. I power up and its fine, then anything from 2 mins to 2 hours later the screen goes all strange, flashing colours and what-not. Then I have to switch off and switch on and the computer asks me if I want to start normally or repair mode. Ive done both just to see and both options allow me to start up ok but then its back to square one- either 2 mins or 2 hours later.
Now, the very FIRST time this happened my computer suggested I download up dated NVidea drives which I did. Nothing happened and the message has never returned.
All I would like to know is, what needs replacing so when I go to the shop I'm not mugged off. And, is it something I could replace?
Thanks in advance for any help
