Red Blocks


Aug 15, 2009

When I look at films using Windows media player and VLC, red blocks appear all over the screen. Has anyone got any ideas to what this might be?
Welcome to the forums!

A bad video card. Check the temperature of the video card with GPU-Z.

80-90ºC is average
115ºC is threshhold
127ºC burnout

Some cards report 100ºC as threshold in Rivatuner, such as 8800GT.
The red dots/or lines are often a RAM issue. The Qimonda ram that XFX and generally all of the OEM's put on their reference boards is Qimonda branded. The problem lies in the fact that the chips can't seem to run at their rated speeds with the timings they are set at. Regardless of cooling you'll most likely have the red ants of doom problem in games using the UT3 or similar engines, Bioshock being one of them. RMA that sucker and tell them that the RAM appears to have gone bad, or the RAM just doesn't work right at all. I got a RMA back from them, still Qimonda, but no longer faces the red dots problem.. ever. *knock on wood* Some people get lucky, getting cards back with Samsung chips, which have looser timings, but rarely have issues that the Qimonda have and can be overclocked considerably more than their Qimonda counterparts.
