I got the same problem with a Gigabyte mainboard Z97 running Win 7 SP1 Pro, fully patched Win, drivers and latest bios . Without starting the ESET Service, the system runs fine. However, starting the service kills the system with a 0x124 BSOD..
How do i enable pre-release update servers without the service?
Any other solution than reinstalling ESET NOD32?
