Fresh Win7 SP1 install randomly freezing, no error msg
Hi,
This week I built a new PC from scratch (done this a few times before so no newbie at it) and installed Win 7 Pro SP1 full retail version.
Everything was working fine but randomly - 3 or 4 times a day - the system froze. No real pattern to it, perhaps happening slightly more when launching an app but hard to tell, and no error message, just complete freeze requiring forced reboot. Not a mouse/keyboard issue as I tried swapping them, plus screen progress bars etc freeze as well. Left for 5-10 mins, no change.
Memtest and Prime95 return no errors. System Health Report all fine. To check for driver problems I formatted the HDD and started again - installed Win 7 Pro SP1 from scratch, didn't do any online updating, didn't install any drivers for GPU/soundcard etc, just kept a really minimal setup. But it happened again!
Nothing showing up in event log that I can see. Most recent item before freezing this time was "The Windows Update Service entered the running state".
Any ideas please? I'm completely stumped!
Thanks.
