Hi,

 

Since a few weeks I encounter the problem that my screen starts flickering green after I'm using my computer for a while.  At first I could still work +/- 20 minutes but the problem starts to appear sooner and sooner and at this point I hardly make it to the logon screen before my computer crashes.

I have a screenshot of how my screen looks right before the computer crashes: https://plus.google.com/104974652713718580318/posts/ihuEyGkiojb

 

I'm using Windows 7.

I'm not using any particular application when the problem occurs.  Just leaving on my computer on the desktop for a while will cause it to crash as well.

The problem does not seem to occur when using windows in safe mode (or safe mode with network)

 

What I tried already:

- try to update monitor drivers (Windows  says I have the latest version)

- My system shows 2 video adapters, I have disabled one but the problem is still there

- De-install, re-install video adapter

 

Thanks for any help.

 

Kris

I doubt it's the monitor. Monitors may fail but they rarely cause the PC to crash.

 

If you are using a vid-card, then switch to integrated graphics. If the on-board graphics work, then the vid-card is the problem. It is probably failing/overheating. A faulty vid-card can cause the PC to crash. You might want to see if there is an updated driver suite for that card however.

 

If you are NOT using a vid-card, then that presents other possibilities. Let us know.
