Windows 7: 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?

i havent attempted any overclocking, and i am having the same problems, but i also get bsod's

the only help i got so far says my hard drive is causing the problem due to either drivers, or hardware, i have posted a lot more information, but no responce, it happens quiet often with me, it locks probably 2x a day, and bsod's close to a dozen times.... hopefully we can both find out the solution to our problems...

How did you discover this?

thanks,

U0

well, i also get blue screens, i loaded up the mini dump files to these forums, and some of the fellow users looked through them, does it ever blue screen for you?

Right - but what evidence pointed to your HDD? And what brand/model of HDD is it?

My system has never BSOD'd in the four months I've had it. Only lockups.

when others looked through the .dmp file they found it pointed to the hard drive as the cause of the issues, i cant tell you what exactly, since i didnt see the dmp file.

1) This could be a bad driver freezing at shutdown. Boot into safe mode and shutdown from there. Do that a few times and see if the problem persists. Also, in the device manager, try showing the hidden devices and removing all the ones that have the problem icon on them. Also, make sure you dont have a USB device plugged in when shutting down.

2) Type GPEDIT.MSC command at the Run prompt. Navigate to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options. Here, locate the Shutdown: Clear Virtual Memory Pagefile option and verify that it is disabled. If it is enabled, disable it by double clicking on the setting and choosing the Disabled option.

3) Go to Control Panel > All Control Panel Items > Performance Information and Tools > Advanced Tools (in the left pane). The problem may be shown here. If not, click View Performance Details in Event Log (Event Viewer). I believe events in the 200 series are shut down events. Double-click them and see if there are any clues.

4) Do you see a lot of networking activity before shutdown? Tweak apps and disable unnecessary services to lighten that.

Thanks for the suggestions, Bill...

This was my thought, but it's looking more and more like a problem with Windows 7, not any particular piece of hardware or its driver. And it doesn't happen just during shutdown - it also happens randomly both while using the system and while it's idle.

I saw the symptom initially with just a USB phone handset connected; later, with a Firewire device and the handset, later with only the Firewire device (no handset). So far, at stock clock with no hardware connected, it's doing fine. So far.

Anyway, the problem occurs so rarely that this test wouldn't tell me much - 99% of the time it shuts down fine, regardless what's connected to it.

I've been monitoring this since I suspected hardware. To date, I've never seen a device icon with a problem.

That'll be difficult - both my keyboard and mouse are USB.

Verified: Clear Virtual Memory Pagefile option was and is still disabled.

"No issues reported."

There are quite a few 200s, but none provide any information other than the duration (there's a wide range), degradation flag (some true, some false) and event time. The only interesting thing is that I don't seen any 200s since I went back to stock clock. Then again, I haven't restarted or shut down much since doing that. I'll try a few of those to see if any 200s pop up.

No idea - haven't monitored that.

In terms of disabling unnecessary services, I'd love to see a list. It boggles my mind that my XP Pro SP3 machine runs fine with only 175MB worth of background processes, while Windows 7 seems to need twice as many background processes and almost a GB worth of processes and services before I even run a single application.

thanks again,

1) Thanks for the detailed reply. Try this MS hotfix.

You cannot make a computer that is running Windows 7 shut down or sleep

2) Make sure the bios and all your drivers are updated.

3) Here is an informative page on your mobo. Try the solutions suggested there.

P6t deluxe wont fully shut down - Asus - Motherboards-Memory

4) If you want to tweak services, go to Blackviper's site. Choose the "Safe" settings. Clicking on each service's hyperlink will give you detailed info about that service. Be careful!

How much time did the Op spend researching and or adjusting the memory settings and the bios voltage settings in order to get his non plug and play Asus P6T enthusiast board stable? I highly suggest you start there.
