Processor spike & system freeze-up is sessions

[psalmeister]

I've been working with a 4 piece rock band for several weeks on a project. Most sessions are less than 16 tracks. I do have plug-ins on most tracks but I don't think it's excessive. After no problems for the first few weeks, I'm now having a chronic problem with CPU usage spiking in the middle of a session, and ultimately the system will freeze up if I don't save and close out immediately. This happens in playback as well as record mode and occurs after running 2 or 3 minutes in either mode. I've tried increasing and decreasing the buffer size and CPU limit, but that hasn't helped. I replaced my os drive after finding some viruses and bad sectors there but that hasn't made any difference either. Could my record drive or processors be going bad or is there something that else that can be adjusted?

Thanks for helping!
