monitor missing from device manager

I recently had to reinstall windowsxp. I also had to reinstall my CD rom,DVD, etc as I had contacted a virus. Now I can not reinstall my monior (viewsonic LCD flat screen). In control panel display it states default monitor. But in the device manager the +Monitor is missing. How can I get it back in the tree route? Also I am assuming that is why I cannot play Medal of Honor on my PC as it states glide installation missing and can not open GLOPEN. Does anyone have a clue? Help me please!!!!Thanks

 

Click the View tab at the top of DM and click "Show Hidden Devices". See if your monitor appears as a yellow splotch waiting for a driver.

 

I tried that it doesn't come up....

OpenGL functionality is usually supplied by your display adapter driver. What display adapter do you have?

 

It still did not work...thx

 

What display adapter do you have and have you installed drivers for it?

 

Aha....adapter......never thought to check. Upon checking I had none available but there was a VGA driver. I reinstalled my adapter and voila! Monitor is now recognized and all is fine with video games. Such an easy fix for my problem. Thank you so much for you help Elvandil! Have a great day!!!!!!!

 

Ah, yes. The default VGA. Glad you got it all sorted out.
