NON-BSOD Win 7 lockup problem - anyone else?
About 2 weeks after setting up a new Win 7 x64 Pro (6.1.7600) system from ADK, I started experiencing rare, intermittent lockups, i.e., the system simply stops processing, screen freezes, audio playback stops, no response to keyboard or mouse input, blink-per-second hard drive activity indicator stops. Holding the power button is the only way to shut down / restart.
Out of the ten or fifteen times this has occurred, it's happened more than a few times during Shutdown, i.e., while the final Shutdown screen's activity icon is spinning: it simply stops and the system freezes.
Frequency is once every few days. It has occurred with and without overclocking enabled, before and after a recent BIOS update, before and after installing drivers for a Firewire Audio Interface (PreSonus FireStudio Mobile) and with two different types of GTS250s - ASUS and EVGA - the EVGA seemed to make the problem worse, while also causing significant audio issues.
No BSOD occurs when this happens and there is no reflection in the Event Log, other than "The system has rebooted without cleanly shutting down first" (Event ID 41) after the abortive restart. Also possibly of note - when I still had it installed, the Firewire AI did NOT go into an out-of-sync mode when this occurred.
This is an ASUS P6T SE w/6GB RAM and Core i7 920 CPU; AMI BIOS 0805; ASUS nVidia GTS 250.
I have restored the original factory image to eliminate the possibility of oddball drivers or software causing this. Presently, the system is configured for stock clock with no external hardware devices installed (no Firewire, no USB other than mouse/keyboard). It's overdue for a lockup event, so I'm wondering if it's possible that external hardware - i.e., of any type - is a possible issue here.
Has anyone else seen anything like this with their Win 7 system?
cheers,
