Multicolou screen on shutdown
Posted on 2011-03-01
I have a client for which i supplied a new Windows 7 Pro pc for. They have an Intel core i7 CPU, with Gigbyte mainboard and Video Card.
We installed a 3rd party application relating to their work on the computer and it caused some issues. We have resolved all issues except for one, whih I am presuming has been casused by the 3rd party application but can not confirm it as such.
The issue is that when the computer is shut down, during the shutdown process it comes up with a multi coloured screen. It has also done this a couple of times when starting up. The only way out is to hit the reset button on the case and re-start the computer.
I can only describe the multi-coloured screen we get as similar to the screen you see when you run a jscreen test on an lcd screen to fix pixels.
It is quite wierd how it happens, but certinaly not consistently.
I reinstalled the video card drivers on the machine, incase something had happened to them.
This did not resolve the issue though.
It certainly does not happen all the time but it does happen.
Does anyone know what this could be?
