laptop display problem

by cstanton / September 18, 2005 1:22 PM PDT

My brother has a 4 year old Compaq laptop running Windows 98 with a display problem. Upper two thirds of the screen display correctly but the lower third repeats the top of the display. I assume the problem is a setting somewhere but changing screen resolution doesn't seem to help

video card failure or driver issue

Greetings,

There are two probable cuprits here. First, the video driver might be corrupted. Download the correct driver from HP/Compaq and install it. Hopefully this will fix it. Second, the video card may be failing. If so, then you might be able to replace it if it isn't integrated (it probably is, though). If the card is integrated, then you would have to replace the whole motherboard.

Regards,

Michael

with laptop video

laptop video is always an on-board video GPU - just the nature of the extremely compact design of laptops generally. When it goes out, there isn't much you can do, as there is no market for plug-in PCMCIA devices to substitute for the broken on-board adapter (unlike a desktop PC where you could stick in a PCI or AGP video card and that would take over from the integrated chip on the motherboard). So you are left with the choice of sending your unit in for expensive service (motherboard replacement most likely) or buying a new laptop.

On the off-chance that the problem is in the LCD screen, you might try connecting an external monitor to it if your laptop has that capability (most do, read your documentation about how to redirect the video signal from the internal screen to the external VGA port...). I suspect that the external monitor would likely show the same weird patchwork, thus confirming that it is a video chip issue.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
