Hello again,
I may have found the solution that has worked for me. It's probably too early to tell, I'll need more time to be sure. But in case it's resolved  the issue for me, I'll post what seems to have worked as suggested on a post I came across from another forum. Take it from a guy who has tried a lot of suggestions, this may be the answer. Heck, I had tried a few other things that I didn't mention in my original post. But anyway, so far, my system and mouse seem to be working very well at the Desktop for the past hour and a half. I haven't tried gaming yet.

1) Uninstall the Windows Update KB977074 (The January 2010 stability and reliability update for Windows 7 and Windows Server 2008 R2).
2) Reboot and let your system sit for a couple/few minutes after rebooting.
3) Just in case... Reboot again, and then reinstall the KB977074.
4) Reboot to complete the installation.
