Laptop Screen Resolution Changing automatically to 640 * 480

The Windows Desktop Screen Resolution is automatically switched into the lowest (640*480) mode. I am using a GeForce 8200 Graphics card with an AMD processor. I am not sure if it is a software bug or a hardware issue. Once manually changed, the resolution switches back to normal though. Please advice.

You best update your video device drivers, go to SUPPORT area of the manufacturer's official site of your video card manufacturer, search for the latest drivers available for your device, download and install it.

Moreover you should try to remove your device and allow your laptop to re-install it. To do so right click on My Computer > select Properties > select Hardware Tab > choose Device Manager > Right click your video device and select Uninstall, restart your Laptop and allow your laptop to re-install the video card. Now you may be asked for drivers again.
Hope it helps.

It is likely that during startup, you have an application that automatically loads that causes the display resolution to use 640 * 480 as the current setting.

Try and disable all your startup items and non-microsoft services by opening the System Configuration utility, go to the Startup tab, click on Disable All. Go to the Services tab, check Hide All Microsoft Services. Then click Disable All. Click Apply/Ok. Then restart the computer. See if you’re still getting the same problem.

If you do, then try updating your graphics drivers to the latest version. If you don’t get the problem, then it is caused by one of your applications running in the background.

Check the services and startup items that was just disabled one by one and check when the problem happens again, this should help you out with isolating the problem.
