High and erratic CPU usage
I've been getting erratically crappy performance for a while now - slow UI, hanging programs and eventually a hanging OS that won't shut down.
It often hangs when I'm using email (Eudora7), but I think that's a red herring because even when I'm not, CPU usage often spikes into the 80% range under very little load and for no apparent reason. Just opening a folder causes a spike to 70+%.
The crash is not simply on account of CPU going to 100% either, the UI will stall for a few seconds at a time with low CPU / RAM utilization, but it seems to progress until explorer hangs. It doesn't seem to be a heat issue - everything is clean and dust free - and that wouldn't explain the cpu spikes anyway.
Nothing really pops out under Resource Monitor and I ran sfc /scannow a couple of times - no integrity faults detected.
Any ideas on how to trace this?
