Hi all, I was using my computer (probably about 5 year old build by now I think) when the display begcan to corrupt, with coloured rectangles checked on both my monitors for about 20 seconds before the display went black. I rebooted and now the fans turn spin up like normal and the DVD drive even opens and closes but there is so display and the keyboard does not light up. I'm guessing this is a graphics card issue? I tried reseating the ram and trying one at a time to no prevail.
The shapes are referred to are known as artifacts, they normally coincide with the death of a gpu. Or at least the first signs that not all is well
Does it beep once when it turns on liek it should normally? Can you see the hard drive light flashing as if it is loading windows? Does your motherboard have an onboard graphics card you can use to see if it is still working? As mentioned above it sounds very much like your graphics card died, if you have a spare or can borrow one from someone that would be the first thing to try.
