Periodic screen flashing

by Hesston / February 26, 2005 10:38 PM PST

Got this Armada 7400 laptop performing pretty well with your help. I intend to sell it to a co worker.
Now the screen will flash for no apparent reason. It has no set interval when it does it.
Running Win 98 366 hz 256 ram. Very few added programs
Winzip, Margi, Walmart internet, WinDVD, Mediaplayer9.
I have surfed a bit with no virus protection.
No screen saver is present. By flashing i mean that it just goes black off and on like flipping a light switch

It does it both off and on line. May be a coincidence but cursor activity sems to cause a flash. However it will do it on its own.

Detective Columbo says.."my wife had flashes"...

1. appliances in the house or other 115v surges. Heavy motors (fridge-freezer-well pump-star gate), or others somewhere close in the Roger's neighborhood.
2. Some PC application, such as Norton sys doc, that refreshes info often, or other PC diagnostic.
3. faint possibility of skinny power supply (less than 250-350 megawatts) that is glitching instead of blowing. Ditto about the hi volts (arc) or lo volts of monitor ( how much dust inside?)
4. radioactive gummy bears, Cylons.
If it were something about the PS/2 mouse (Tom or Jerry), the PC would likely lock up. You can always borrow one for a check. If it were about the PC video, it would likely knock the colors and screen size back.

That's a bad idea. Since there's so little on it, boot up the RESTORE CDs and start over.

Since Free AVG is "free", it seems irresponsible to go without virus protection. See

As RP said.

Surfing with no protection may not be a wise thing to do.

I have surfed around for years and my anti-crudware scanners/blockers have had very little to do.

Some folks seem to be a magnet for that stuff.

Five minutes on the web and their toast.

Some day I'll figure out how they do that.
