HP Laptop Screen colored lines appear

by lunachik24 / February 25, 2009 6:00 AM PST

My Pavillion dv9000 entertainment laptop works perfect one minute then will suddenly show colored lines all over the screen, sometimes circles, spots, all over different colored "snow". It then is unresponsive and I have to force it off. It turns on in safe mode sometimes visually perfect, other times with transparent blue squares that will change when the mouse travels on the screen. Then I restart and it will work fine for sometimes an hour and do it again. I ran spyware and maleware programs but nothing showed up on that.

Two Possiblities I Know Of..
by Grif Thomas Forum moderator / February 25, 2009 11:56 AM PST

1. The graphics driver needs to be reinstalled or updated.. Visit the manufacturer's website to download the newest video driver, then install it..

2. If that doesn't help, then the display screen is going south.. It could be a cable or the actual screen failing.. Either way, most home users will need to take it to a repair shop.

Hope this helps.

thanks for the reply. I just bought the extended warranty on the hardware for $50 for a year. I figured that would be alot cheaper than repair if it is going bad. I reinstalled the nvidia driver and it seemed to work but then happened after a few hours of use once more. Amazing how a week after my year warranty expires something has to mess up!

That line is known for this.

Be sure to call it in NOW. NEVER DELAY on these since you don't want to know how much if you had to pay for repair.

Those symptoms are usually the GPU going bad ...

and as Bob said, your first course of action should be immediate warranty repair.

It would not hurt to try new drivers but those symptoms are almost always hardware and not software.
