I got a virus a couple weeks ago that disabled my laptop's built-in video card and reduced the maximum screen resolution from 1366x768 to 1024x768, it can no longer run Direct3D, or OpenGl as well, not even simple applications that use them. I can also no longer troubleshoot or update my PC through the options in the Control Panel, it says an error is preventing it from doing so and it won't automatically go to sleep when I shut it.

The attachment is a screenshot of my system specifications through "Control Panel\System and Security\System"

Also I see that there are 2 display adapters damaged, it says they are "Mobile Intel® 4 Series Express Chipset Family" with this message:

"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

I tried getting help for this in another thread, which is located here in case you might be able to find any information from it useful.

Thanks in advance.

What the virus probably did (Im guessing) is delete the drivers, at least the registry entries. I would go through and uninstall any drivers you have for it, and download and reinstall the proper drivers for your video card, and see if that fixes the problem. Id link them, but I dont have your actual specifications. Im guessing its an intel graphics chip from your error, but I don't like making guesses. What model laptop is it?

I've been thinking the same thing, because Spybot gave me a few messages on restarting several times that a few entries from the registry have been deleted.
Just deleted them and they're automatically reinstalling, by the way it's a HP G56 Notebook PC.

I just noticed that my attachment in my previous post didn't attach, sorry about that.
