I respectively disagree.
Driver: Small piece of software that allows the Operating System to communicate with a device
Either Windblows looses the address to the driver, or it doesn't.
Freezing up of the graphics suggests to me other problems.
1) You don't have the newest version of Adobe Flash Player,http://get.adobe.com/flashplayer/
(I would click on the square box to the left of -
Yes, install McAfee Security Scan Plus, ya-da, ya-da.
McAfee bl-ows, and will just slow your computer down. Clicking removes the Green checkmark.
You may also have to use the Adobe Flash Player Uninstaller tool.
The new version will Not automatically uninstall the old version, and if the old version is there, the new version will not install. Post in a Comment if you would like guidance with this)
2) Make sure your JAVA is up to date,http://www.java.com/en/
3) Your brief video suggests you may be looking at a video.
If it is a game, it may be that your Desktop PC does not have the graphics power, to run it.
If it is a video, I suggest your desktop computer is dirty inside.
It's overheating, and causes freezing.
(Processor is overheating. Also look to see if the Thermal Paste on top of the Processor; and under the finned Heatsink; needs replacing)
Need more detailed info?
I need the manufacturer name, and model number of that desktop computer.
It's on the back next to the Windows product key, or up on the side of the computer tower.
