Hey there, so I thought all was going well, but now having major problems. I could just casually be on the internet or playing a game when the screen freezes. The screen sort of turns into a chequerboard and the alternate squares turn to a pinky redy purple colour and jump up and down. Im not able to move the mouse, and nothing responds to keyboard presses. The only way I been getting past this is holding down the power button, which of course not good for my computer. So any advice would be a great help.
Thanks.
Thanks.
