Random screen blanking

Hello !

I have installed windows 7 ultimate w/SP1 with 3.2 p4 and geforce 6200 agp. I am experiencing random screen blanking for about 1 sec. No matter what i am doing , watching youtube, working in notepad , librecalac ,etc.

I used the same install media for second machine and it works fine but is a dell. Winxp pr worked fine with no problems. Ran Ubuntu linux for 45 days with no problems either.

This only happens with wndows 7 ultimate w/SP1.

Any ideas on what to check ? Nothing in event viewer relating to display errors.

thanks for any help in advance.

I saw microsoft updates installed 8 dot net updates and that seems to have fixed the random screen blanking. Been running awhile now and no blanking at all.

I have finally figured out that it was the ethernet card settings which wanted to turn off machine when network was idle or what ever that setting is. I unchecked the box and haven't had one problem since.

I have just installed SP1 on Win 7 Pro and i'm getting this "random 1s of blank screen" problem.

Could you be a bit more specific about the setting you changed to fix this, like a screenshot of the window witht the setting?

Thanks-
