|I'm assuming you're using the built in LCD display on this computer. |
If you are NOT and you are using an external monitor, there are other possibilities for your stretched display.
"The display's native resolution is 800x600."
You may have the resolution set to 800X600, but this model's native resolution is 1024X768 !!!
All LCD displays have a native or optimal resolution that looks the best - usually that resolution is also the maximum resolution of the display. You can choose other resolutions in Windows (or whatever operating system), but they will not look as good as the native or optimal resolution.
The most noticeable thing is text is not as clear in other than the native or optimal resolution - you can't do anything about that in Win ME and below, but Microsoft has Clear Type for 2000 and above.
More info native resolution:
In the case of this display, any resolution that has a 4:3 ratio will be proportioned correctly, if other things are right. .
If the display is truly stretched at 800X600, it's also stretched at 640X480 and 1024X768.
This system was probably made in 1999. It's extremely unlikely anything to do with the Chips and Tech video drivers are the case of your problem.
You probably have the wrong Monitor drivers loaded.
When brand name systems have their original brand name supplied software installation on them, the Monitor type is set to suit the model.
When you merely load Windows on the hard drive, the default Monitor type is probably not right, for a laptop.
I'm guessing that these are probably the right drivers:
RIGHT click on a blank area of the desktop screen - Properties - Settings
Advanced button - Monitor tab - Change - Next - Display a list....., Next - click on the circle beside Show all hardware
In the list on the left -
Standard Monitor Types - Laptop Display Panel (1024X768), Next - Next - Finish
