I have a client with a Hp Compaq nx9420 note book running Xp Pro with SP3. Last week the screen started blinking out of the blue. It’s a quick blink just like the blink of an eye but it’s working on her nerves and I can’t figure it out. The last thing I did on her system was install a Webcam (Microsoft LifeCam VX-3000 Pack) but have been installing them on multiple systems with out anyone else having this problem. One interesting thing I noticed was a caught a quick glimpse of the hour glass after each flash\blink. So far I’ve tried Checking the AC power, added an external monitor and it also blinked along with the note book screen, uninstalled the Webcam software, updated the graphic drivers, updated the BIOS. The only thing I can think of next is to physically check out the video board. I’m new and have never done this but I do have the manual from HP and am only going to see if something came loose. Any suggestions would be greatly appreciated.
