Last time I've noticed a problem that sometimes my keyboard input is stuttering and freezing for a few seconds; does this mean I have some keyboard hook buggy or gone rogue, or there can be another reasons? How can I check keyboard hooks installed in my system?
PS I have MS Security Essentials installed and checking periodically.
UPD it seems this happens when any of CPU cores is utilized up to 100% by any program. Any ideas?
UPD2 I have i5-3550 CPU, 16GB RAM, SSD for the system disk.
UPD3 after some more experiments - this problem is not bound to CPU usage. It happens even when total CPU usage is less than 10%.
