Display loses signal when streaming video, works fine in games?

[atm0706]

I hope this is the right forum...

Anyways, my computer has started to lose the dvi signal whenever I try to stream video from the internet. I have tried watching trailers on steam, going to youtubes website to watch video, and tried vimeo. All these sistes cause my computer to lose dvi signal and the only option is a hard shutdown since I can't get anything back on screen. I can't hear any audio after the screen shuts off either.

Everthing works fine when playing games in full hd 1920x1080 with aa on and everthing, no black screens. It works perfect. I can also watch movies I have stored on my computer with no problems.

Everything seems like its working perfect untill I go on youtube/vimeo etc. Then the screen just shuts down. I don't know if this is a screen issue, a video card issue or what...

Please help!
