Ok this morning my computer was working fine. I decided to install new drivers for my graphics card, so I do. Then I restart and I get all these wierd lines appearing all over my screen randomly.
I think to myself "those drivers must have duffed it up". So I uninstall the drivers... still the same problem. My computer could do with a format so I might as well kill 2 birds with one stone. So I format my pc, completely restoring it to factory setting and guess what: I've still got the same bloody problem.
This must be hardware problem I thought, so I decided to go and test my monitor on my family pc. It works fine, no wierd lines, no problems at all. Then I plug it back into my normal PC and get the same bloody lines. They don't happen all the time just every now and then, but the are very annoying.
