For the past few days my laptop Model HP G61-409CA has been displaying broken black and white horizontal lines and discoloured random squares on my screen. When it freezes the screen and mouse stops moving and the screen goes blank for about 5 seconds then comes back and an error (displayed in the subject title) appears with a yellow triangle. Ive tried to download Catalyst Control Centre because I cant seem to find the folder or the program on my computer, but when i tried to instal something similar from http://support.amd.com/en-us/download/mobile?os=Windows%207%20-%2064#amd-catalyst-packages the computer displayed a Blue screen and had to shut down.
Please let me know what needs to be done ive tried updating all my drivers aswell!
