Weird problem, need second opinion

Ok, try this: Open the Task Manager and select the Performance tab. Leave it open. When the PC "freezes", check the display and see if the CPU has gone to 90% or more. If yes, and it doesn't show up in the Processes tab, you may have a system service that has gone nutz or more likely, some malware (virus, adware, spyware...). If no, you may have a hardware problem. If you have a diagnostic disk, you can run extensive diagnostics overnight.

Yep, it froze and then showed 100%. Seen it randomly bounce up to 81% and 94% but only froze at 100%. The only process that shows numbers this high is System Idle Processes.

Sounds like you've got some malware that is running a hidden system process. If you can see your network jack or the port in your router, when it goes 100%, look at the lights to see if it's transmitting/receiving at a very high rate. If yes, you have a bug than needs to be removed. Run your antivirus, SpyBot, AdAware, etc.... Some malware simply cannot be removed no matter what you do, and a wipe/reinstall might be needed.
