Why is my video screen purple?
Recently when I turned on the computer and monitor the computer beeped at me with three quick beeps. The three beeps repeated every ten seconds or so and the system never came up. I tried to reset and nothing happened except the beeping stopped. I turned the computer off using a switch at the back of the machine and back on again - the beeping started up again. I left if for a while and after checking that all cords/plugs were firmly in place, repeated the above, leaving the machine off for a while longer when turning it off. This time the maching booted up without an abnormalities - except then, and now any time, all of the colours on the computer, from desktop to when I'm in a program, are all in shades of blue/purple. I've tried resetting the colours through the control panel but even the colours in the panel seem to be out of whack. Is there anything I can do to return the colours to normal?
This question was answered on December 11, 2002. Much of the information contained herein may have changed since posting.That beeping sound was something called a "post code" In its computer-like way, your PC was trying to inform you of a video problem.
First, be certain your monitor is plugged in fully to the 15 pin socket on the back of your PC Use the set screws attached to the connector.
Of you still have a problem, you either have a mangled monitor cable or damaged video card Once again, be certain everything is put together firmly and no wires are pulled tight Your video card should be plugged firmly in place and fastened to the back plane of the chassis with a bracket screw.
On the outside, you could have a bad video card, but I doubt it.
