I've been having some problems with my computer recently (blue screens). I'm not 100% sure what's causing it but I have a strong feeling that it may be a faulty graphics card. The reasons why I think it might be the graphics card is because: the screen flickers, I once got a shock when attaching the monitor cable to the back of the graphics card (is this even safe?), and Windows attributes the error to a 'device driver'. Now back to my main question, can a faulty graphics card cause a monitor to "break"? Just today, my monitor is displaying all the colours wrong (a massive red tint). I've tried it on another computer and it's definitely the monitor displaying incorrect colours.
