Sounds like you have hardware failure on your PC, either the video card, or your monitor is going bad. Since your mouse is affected also, It could be the motherboard on your PC also (perhaps you have an integrated video card). You should contact your PC manufature if it is still under warrentee and see if they can repair it, otherwise you will need to take it to a local IT shop and see if they have replacement parts for purchase.:P Advice offered, If you need more help it is advised to seek the council and advice of paid professionals. The answer is always 42, or reboot.

i run windows 7 and today when i logged in facebook the white part of thw site had pink stinks like a lot of pixels were broken. then i closed the window and i noticed that the desktop had the same stinks. i tried to google the problem but suddenly the mouse pointer stopped moving and the whole screen was frozen. i shutted down my laptop using the boot button and sterted the system again. everything was ok, i saw the screen with the windows logo (windows 7 with the four colours logo) but after that the screen went blank and it wouldn't do anything. i tried to boot again and again but the same problem would occure. i booted in safe mode and restored the system to the day before yesterday. then i booted again. this time windows loaded normaly but the pink stinks were still there. i tried to google the problem again and the mouse pointer stopped working again and the system was frozen. please can anyone tell me what is this? probably a virus but i can't find out which one?
