Multicolou screen on shutdown

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?

Please have the machine scanned from the virus and or check the monitor cable.
I mean to say reconnect the monitor cable and if the proble persists replace the monitor cable and check .

Thank you.

The PC is brand new, like 1 week old, so I dont think it is virus related.

I know the monitor cable is a hdmi to dvi cable that comes with the monitor. Hence, HDMi out of moinitor and DVI into graphics card.

Will try replace that and see

Boot the computer in VGA mode and monitor the computer. If the computer works fine in VGA mode then the problem is video drivers. Need to install the updated driver.

The reason why you get a multicolored screen is because of a bad driver. Not necessary video driver but can be the video driver.


Check in device manager for any yellow exclamation marks.

Also can try clean boot to check whether its any third party software at the start up that is creating this problem.

Clean boot process

Clean Boot Process
Click Start-msconfig-click on services tab -put a check on hide all microsoft services and then click disable add. Click on startup tab and disable all.

Restart the computer.

I have received this computer back from the customer to find out what is going on with it.  I tried to upgrade the graphics drivers remotely from the internet.  upon reboot it came up with BSOD error with Win32.sys file I think it was.

Since getting it back to me, I have tried a new graphics card and new memory and I could not get the computer to even boot.  Turn it on at the power and the system does nothing.  There is power and fans working, no beeps, no video.  
I thought it maybe the mainboard so got a new motherboard (Asrock) and a new Radeion 5670 graphics card.  Installed both with different memory chips as well,  Still nothing, power to components but no video no beeping.

Could it be the CPU??????  It is an Intel Core i7-950CPU.

Now when I turn it on I get power lights and fans, but no video screen at all, no even mainboard BIOS screen on 2 mainboards.
