What is the reason of blue pixels (noise) on screen?
My problem is, that if I play a game the screen gets blue noise pixels. If i reboot, even the bios prompt is not only black but with some blue pixels dancing around.
What could be the origin of this behaviour?
Please post your solutions to a problem like this. Maybe it will provide guidance to some other people with similar problems.

Unfortunately, this is almost always caused by the the GPU not making proper contact with the traces on the video card board. The most common cause is cracking of the bump underfill material where it meets the package solder balls. If the card is still under warranty, get it repaired.
If this is the issue, it will be worst when the card is cold as less serious when the card is hot -- particularly when you first start having problems. It will tend to get worse over time too.
9I fixed the problem by switching the monitors, so monitor 1 is now 2.
Maybe it was a cable issue and now it makes proper contact now.
