Every now and then when doing mundane tasks the system will completely freeze sometimes so bad that audio buzzes, if im able to open task manager it shows cpu usage at 100 percent and will either show system using like 50 percent or everything will look normal and barely add up to like 5 percent total while it still says the total is 100, usually it gets so bad my pc is unusable for a few minutes.

I've been having similar problems lately, What's your system look like, what are your specs?

I'm running at

i7 920
Asus P6t motherboard
12 gigs (6x2gig) of mixed 1066 memory modules
Gtx 660
Windows 10

Look for background tasks, possibly malware.

I did get a Nvlddkm.sys blue screen which is Nvidia related, and what fixed it for me (at this moment) is doing a system restore from before an nvidia driver update
