My HP laptop boots up and runs fine. Sometime works for hours without problems, but at times when you walk away and come back to it , when you touch it the screen goes blank displaying color screen and white lines running up and down.
I've had some people tell me it could be a damaged video card. Is this possiable? It's weird that it seems to shut down when you touch it, almost like you've shocked it. Any help would be greatly appricated. Also, if it's the video card whats the cost of replacement on a Laptop, is it worth it or just buy a new one?

Re: Lap top screen goes blank all of a sudden
I assume that when you dont use your computer you put it in a sleep mode by pressing sleep button ..so if this is the problem you are facing than there is nothing wrong with your video card and solution for this problem is that remove both the power cables and also remove the battery for time being, after some time put back your battery in the laptop and plug the power cable and restart your laptop it will work fine........... ------------------------------------------------------------------------------------------------ Was this solution helpful.Show your appreciation by rating it.

I had the same problem. The first time I used the HDMI port, it showed up perfectly on my TV.
But, next day I get a blank screen. When I rebooted the laptop it would show the windows splash screen and go blank.
I won't tell you how many things I tried that didn't work.
What you have to do is stupidly simple. Right click on the ATI logo in the systray, and then left click on catalyst control center. Run the basic wizard. I'm not sure which screen it is on but choose "clone". Suddenly, a miracle happens, and it works.
I don't know what kind of genius decided to make a second display not work at all unless you ran a wizard. But thats what I did to fix it.
Are you running on battery or AC? Try using the power cord, remove the battery and see if it continues. I have seen a battery that is on its last legs do some weird things to a computer. Also, check your power management setting. Control panel, power, and set the computer to "always on" just to see if it could be a power management setting. If none of this works, i would back up all your files, and try to reload win xp from scratch.
More than likely this is actually going to be a processor error. Many years ago, I had this same problem. I was the worlds worst about leaving my lap top on the carpet, a pillow, the bed... where ever. At any rate, I fried the processor, since then, I have replaced it and it works just fine now. If you haven't already done so, allow your computer to set for a few hours to cool. Many times if the processor is over heated, it will not boot up. Try to boot up after 3-4 hours. If not success, I would return it to a HP authorized repair dealer or to a local repair show...depending on if you still have a warranty and due to cost. A Mom and Pop repair shop will more than likely be greatly less than an Authorized HP Agent. Let me know how this works for you!
sounds like the backlight has gone....test with an external monitor....if the external monitor works without any problems...the backlight has gone...better to get a professional to do this as its kind of fiddly and involves taking the screen apart
the pc is standing at command prompt, which means it is unable to find the boot.ini file required to boot into windows
When you say you pressed F8 did you keep pressing it until you got a menu saying Safe Mode,last known good configuration, start in VGA mode etc, if so use last known good configuration and let it reboot.
If still nothing then you will need the windows cd to perform a system repair.
Have you tried pressing F8 on boot-up and log into safe mode under administrator, no password, and right click on any empty space on the desktop, left click on properties, left click on settings, select a lower resolution,( e.g. 1024X768 ) select apply, select ok, reboot, log in as normal
