Hello, recently my video card is burned, and we had to send it in for repair, after we were told that it happened due to overheating. And it was like this: I've been playing cs go, then there is a screen with brown stripes and the computer does not respond to commands, it had to turn off the power. When the flashing strip of white appeared in the upper right corner of the screen, and then we gave it in for repair. But now the situation is repeated, and the meat appears brown with stripes screen, but this time the computer is turned on. But it includes a very long time and is still in recovery mode ... What to do whatever the situation is not repeated and we are the meat does not have to pay a lot of money for repairs if it vopsche second time repaired. Map: ASUS AMD Radeon r9 270x
You probably need better cooling inside your case. You might..
1) Buy some high CFM fans that have low noise levels. Put a fan in every available space your case has. You can reduce the videocard's heat by reducing Anti aliasing levels.
2) take a can of compressed air and blow all the dust from every thing inside the case.
