1. The article [Q323786] provides general troubleshooting steps to isolate problems that are related to video adapter drivers or video subsystems concerning symptoms of display problems as follows:
? Computer fails (general protection faults or invalid page faults)
? Computer stops responding (hangs)
? Printing problems
? Unexpected mouse behavior
? Unexpected colors
? Screen redraw problems
2. Check for conflicts in ''Device Manager''. In some cases, a hardware conflict may manifest itself as a video problem.
3. The first thing to ensure is that a ''device has not been disabled in a hardware profile.'' Also, please read ''Troubleshooting Device Conflicts with Device Manager (Q133240)''.
4. You may use the DirectX Diagnostic Tool to determine the video driver versions, provided this tool is installed on the system:
a. Click Start, Run, type the following line exactly as shown or else copy and paste it there, and then either press Enter, or click OK.
c:\program files\directx\setup\dxdiag.exe - (being sure the correct path in the example is used)
Note: Otherwise, use the Windows Find function to see if the file DXInfo.exe is installed on the system. If so, double-click it.
b. Click the Display or the Display 1 tab.
c. Under Drivers, note the version number on the Version line.
Note: If multiple video adapters are installed in your computer, repeat #b & #c above to determine the driver versions of each additional video adapter. When finished, click Exit.
5. Set the Windows Standard VGA display option in the Control Panel:
a. Click Start, Settings, Control Panel, Display icon.
b. Click the Settings tab and then click the button labeled, Change Display Type in Win95, or the Advanced... button with Win9x, and select the Adapter tab.
''WRITE DOWN ALL INFORMATION REGARDING YOUR CURRENT ADAPTER. YOU MAY NEED TO KNOW THIS INFORMATION LATER''.
c. Click the Change button and follow the instruction until you can select Show all devices/hardware for your version of Windows. Be sure you don't use the option to ''Search for a better driver.... .'' You must set this manually.
d. In the ''Manufacturers'' box click ''Standard'' display types. This option should be at the top of the list -- if you can't see it now, scroll upwards.
e. In the ''Models'' box, click ''Standard Display Adapter (VGA)'', and then click Next or OK - depending on the Windows version used to ensure the selection made is accurate.
f. Click Close, or whatever to exit that dialogs.
6. While at the ''Display Properties'' (Click to see an example screenshot) dialog, click the Settings tab if it's not already in focus.
a. In the Colors palette box, select 256 Colors by using the drop down arrow at the right side.
b. When finished, restart Windows for these changes to take affect.
Note: Then run/use the system and test for problems. If the anomaly disappears, the problem was certainly caused/related to the particular video drivers in use, or is related to the subsystem video adapter itself. Perhaps the drivers are corrupt and require a reinstallation, but I would suggest the manufacturer's site be check for updated drivers first.
7. Consider adjusting the ''Advanced Graphics Settings'' (Click to see an example screenshot) a notch lower, or higher and observe the results (Click Start, Settings, Control Panel, System, Performance, Graphics).
8. You can benchmark the system's video performance at various settings to determine the best one to use and for most people, an unscientific test may suffice. If using Windows 98, click Start, Settings, Control Panel, Display, Effects and place a check mark in the box labeled, ''Show window contents while dragging''. Click Apply and then click OK to Exit. This setting gives the video card a good workout. After this, drag several windows around and note whether the movement is jumpy or smooth. Try different resolution settings and color depths (Control Panel, Display, Settings, Colors and Screen Area) and note which setting gives the best movement/result for use.
