Didn't your IT note this?
I have a multi-display set up at work. One of my monitors continues flashing every few seconds. The system isn't locking up like others have had issues with. IT desk at work has disabled the two msconfig start-up items that were causing the problem and it fixed the issue, but now the screen is flashing again. I have had to continually update then rollback the display drivers in order to correct the issue. Every time my computer sleeps I return to the same monitor flickering again and again.
Please help me find a permanent solution!!
Thanks!
