I have an i5 system running Windows 7 64bit.
Over the last few weeks, my programs have been freezing (error: not responding), bootup takes 5 min or so, and the whole system seems to hang - sometimes for minutes at a time... the event log says the problem is Standby Performance Monitoring, Boot Performance Monitoring, and Shutdown Performance Monitoring, all with 'critical', 'warning' or 'error' signs. The event ID's are 100, 101, 300, 302.
Does anyone know what might be happening? It's taken me 15 minutes to write this with all the freezing and waiting for the computer to 'catchup'...it's driving me insane!!
I hope someone can help me
