When selecting sleep or shut down, the PC stays on and windows hangs with a black screen on the monitor.
I'm thinking it's something to do with HIPS. I done a quick test, disabled then re-enabled HIPS and windows went to sleep mode without any problem.
I've been running Eset for a few days with HIPS in smart mode mostly.
Do the HIPS reports look normal ?
