After restarting it again, the multicolour problem is gone and it shows in normal colours, but the resolution has been changed to 800x600. I tried to change it back but all the text went weird and the background was black with green slits(kinda like the Matrix).
The graphics card I have is the NVIDIA GTX 470. I only had it for a little more than a year!
So before I take into the repairs, I want to know if it's just a graphics card problem or if it's something else. I'm kind of in a rush because I need it for work and it's better than the laptop I'm using now.
EDIT: After leaving my computer off for 1:30 hour, I can change back to my 1600 resolution like normal. BUT, I just received a warning in my taskbar saying something something about my NVIDIA driver stopped working and has recovered. It seems to run normally now, I will see how long my computer will last until or if it shuts off again. Should I get a new graphics card instead?
EDIT 2: Computer shut off suddenly again after 5 minutes
