I have just built a brand-new rig from entirely new parts 2 days ago, and at random times when I'm browsing the web, my screen goes black, and nothing responds. After restarting my computer, this problem persists, although never on the same pages.
I run Windows 7 SP1, and have all the new updates. I use chrome as my browser, but it has never done this to me before on any of my previous computers.
Although I do not believe it to be a memory issue, I have run memtest and gotten 3 passes in a row. I have not otherwise run any diagnostic or stress tests on my PC, as I am not familiar with how to do so.
Any suggestions are very welcome, and I just want to know if it's a software problem, or more likely a hardware issue.
I am having a similar problem. After building my new pc and installing my new OS (windows 7) I am finding now that my screen will randomly scramble while browsing with firefox. Half turns black the other half looks like digital scrambling of snow from a television set. When the problem occurs my dual display doesn't seem to be affected. It usually happens when there is some sort of video playing. If i press a random combination of CTR+ALT+DEL, ALT+F4, and CTRL+ SHIFT+ ESC I can get the scrambling to disappear somehow..it's very confusing.
