Dropbox or many others to post a pic.
I have a Acer ASPIRE M5910 Microsoft Windows 7 Home Premium... desk top and It will start a buzz sound and I get these lines similar to rail road tracks that come on the screen and go off and come on again it does this for about a minute or so then the pc freezes up and I have to reboot. Its fine after the reboot and only does it once in awhile.\
Before its done it quite a lot and I was getting the blue screen too, but I reinstalled windows about a month or so ago and haven't had any trouble tell yesterday I got the lines and the buzz again first time since the reinstall and so far only once. I have a picture of the lines I took with a camera to show but I don't see any way to upload it
thanks for any help or suggestions
