I've been having probs with my puter the last couple of days. Seemingly simple things like opening an internet browser or playing a film were using 100% of my cpu in task manager. However, totalling the CPU usage from the visible processes would only yield 20-30% or so. It was almost as though there was a hidden process which was using the rest of the CPU. So, I downloaded "Process explorer" which showed that "Hardware interrupts" were using a random percentage of my CPU, anything from 5% to 90%.
Any idea how I can get my speed back?
Is it a hardware problem is hardware interrupts are slowing things down? I've not changed any hardware lately.
