Sleep Mode Issue

weyland yutani · 23 Jul 2012 at 12:28

When I wake my pc from sleep mode I often find a "System Interrupts" process is using about 20% of the CPU.

Any idea what this is and what may be the cause? The only way to get rid of this high idle usage is to restart, which defeats the purpose of using sleep mode

My system runs smoothly otherwise on a year old Win 7 64 bit install. I'm guessing its a driver issue of some kind. Any ideas?

seems to be a symptom of bad drivers or multiple instances of the same piece of hardware conflicting with each other.

have a look in devece manager to see if anything stands out

hard drves and controllers seem to be big culprits, chkdsk your drives for bad sectors and reinstall your hard disk controllers
