I'm helping out a friend with his fairly new laptop. It's a hp pavilion zv5000 laptop, Windows XP, Athlon 64 chip, etc. It's a nice laptop. He got it within the last 6 months. About every 30 seconds, sometimes more sometimes less, the computer will just lock up and you won't be able to do anything on it. You can still move the mouse around the screen but it won't change anything running. Then, after a second or two, again sometimes more and sometimes less, the screen goes black and comes back up again. It doesn't seem to interrupt anything you've been doing, and anything you did with the mouse while the screen was frozen still happens. For example, if the screen locks up and I close the window, I won't see the window close, but after the screen turns black and then comes back again, the window will have closed. Also, while I'm typing this I can keep on typing while the screen is locking up, and anything I type will be there when the screen comes back even though I couldn't see it as I was typing it.
That 30 seconds is an estimate and it seems to do it more often when the computer is working harder. And for some reason right clicking somewhere makes it do it almost every time.
The video card is a NVidia GeForce4 440 Go
I have run zone alarm's antivirus, fully updated and a few spyware checks, but they didn't find anything to fix this. Zone alarm came up with a few viruses but cleaning those didn't fix this problem.
I don't think it's overheating because it's not getting very warm anywhere and the motherboard temp is 37degC.
In safe mode everything works fine.
I've tried uninstalling and reinstalling the drivers. I used the driver manager to do it, but that didn't help. When I downloaded the drivers from nvidia's site, they didn't recognize the video card.
I can't figure out what the [bleep] is going on. If you have any ideas, please help or ask me any questions.
Thank you very much
