My Intel Core 2 CPU (Dell XPS M1730) runs at 40% or more all the time, with no applications loaded. Ran MSConfig, selected diagnostic startup, and tried again, but with the same result.
Task Manager shows no CPU usage from running processes, but Process Explorer shows 40-50% under Hardware Interrupts. So been Googling this, but it's all very depressing. No improvements...
I checked that my HD is set to DMA mode (5). I had two entries for IDE Primary in Device Manager - following other forum advice, uninstalled both and rebooted twice. both now back and in DMA mode again, but same CPU usage. Not sure what else to do, I feel I am on a wild goose chase.
This is a dual boot machine with XP 32 and 64-bit and the problem is only with the 64 bit O/S: I tried booting into XP 32-bit and the Hardware Interrupts there are minimal - 1% or 'n/a' in Process Explorer CPU background activity is much lower.
Ran virus scan & Malwarebytes.. nothing relevant.
Hope someone can help!! Thanks,
Martin
