Me and my brother are completely stumped on this problem. The computer freezes at exactly 1:00AM every single day, and after that, everything is super sluggish.

No Antivirus is set to scan at 1:00AM, it's really weird.

AMD Phenom 9850 Quad
GeForce 8500 GT
Asus M4A79 motherboard
LG Blu-Ray
Random DVD Drive
2 HDD's.

Anybody have any ideas? I'm stumped.
 
I'm almost certain it's a scheduled system task that's causing the problem. Not necessarily an update - that's just one of several dozen possible events that could fall under the general category of system tasks.

Go to the Start menu and type "task scheduler" in the search bar. Open the task scheduler and take a look at the list of Active Tasks. See what's scheduled for 1:00 AM in the "triggers" column, and you'll probably narrow it down to one or two possibilities. I do think a hard drive defrag is one of the things that is typically scheduled at 1:00 AM by default, so that definitely sounds familiar.
