Hi, I have a Gigabyte GTX 260, and yesterday, the colors suddenly changed so that everything was having a yellowish tint. At times it switched between the normal color and the tint quickly (several times per second) and sometimes the tint would stay for minutes and so on. When I restarted the computer, it came back to the normal colors and stayed that way until shutdown. But today, when I booted up, the colors again had the tint and this time it wouldn't go away. When I switch to the other DVI port, there's a blue tint to everything. Here're how the test image at http://www.abchomestore.com/colortest/Color_Test.gif looks like when I connect the cable to the two ports: http://imageshack.us/photo/my-images/839/07052011429.jpg http://imageshack.us/photo/my-images/534/07052011430.jpg From this I guess we can rule out the problem being in the monitor, drivers, the cable, the ports themselves or the DVI to VGA converter I use, since one port doesn't show blue and the other doesn't show red. So the problem has to be the card. What I can't figure out is why this happened. In fact, the exact same thing happened to my last card about 3 years ago, which was an Inno3D 7900GS. Could it be the heat, because I live in a hot country and the room temp is about 30 deg Celsius now. This time the problem started happening when I was in the desktop maybe 10 minutes after playing Crysis 2 for about one hour. The card's about 2 years old now and the GPU temp is about 80-85 deg Celsius when I play a game. Anybody got an idea on how or if I can fix this? Could using a monitor with a native DVI input help in any way? Thanks in advance!
