Blocky Screen

By ghector ·
After my computer is on for more than 30 mins, the screen goes white fuzzy, blocky. The system is still running behind it but you cannnot see any of it. The heat sink maintains a regular temperature. The graphics card is slightly warm. Any idea?

To narrow down the source of the problem, run the system with a different monitor.

If it still fails in the same manner, try a different video card.

I would try a different monitor, if it still occurs, then replace the vidoe card. Also you can try that monitor with another system, if it still occurs try replacing the cable.
