|My amd radeon 7770hd gives no signal to my monitor when i play certain new games. The video freezes for 5/10 seconds, then i have no signal, then video comes back. I have this problem randomly maybe after 20 min when the video card starts getting stressed maybe after 4 hours, there can be 10 minutes between a crash and another or there can be hours. All drivers are up to date with catalyst, i also installed all recent drivers for the motherboard; the gpu temperature when stressed out never goes beyond 60c degrees and all the games run smoothly between 70-120 fps.|
I have a vga monitor attached to the video card with a vga-dvi adaptor but that doesn't seem to be the problem since windows runs always good.
