Windows 7 "Unexpected Shutdowns"

I upgraded my 32 bit Vista Home Premium to 32 bit Win 7 Home Premium, using info from the Win 7 Upgrade Advisor download & the Toshiba Win 7 Upgrade Assistant download. The install was seamless, but it took about 4 hrs. I then ran Windows Updates, & updated my ATI catalyst control manager (as per W-7 upgrade advisor). Although my machine is running very well, it sometimes starts flickering with a blank screen & shuts down. Then Windows restarts & comes on with a message that says "Windows is recovering from an unexpected shutdown" & an option to report the problem & find a solution. I always report it but a solution has not shown up in my activity center. There is no pattern to the shutdown, once it happened while the screen saver was running & 2 other times I was running malware scans. It has shutdown a total of about 6 - 8 times in the first week. Does anyone have any ideas about what's going on ?

Check the event viewer and see if you see any errors, or even warnings around the time the system shuts down.

You can't always trust the Windows updates for hardware. They pushed a Nvidia update when I was running Vista and it messed up my system.

I couldn't find anything in the event viewer, but one of the details in the reliability monitor was .. The computer has rebooted from a bugcheck. The bugcheck was: 0x00000019 (0x00000020, 0x8580d000, 0x8580d300, 0x08600000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 103109-27705-01.

Thanks Saltgrass, I went back & dug around in the event viewer & set it to full page, then I could see the events. I found 8 critical events in the "Summary Of Administrative Events", all 8 of them were as below :

Results for: Microsoft Product: Windows Operating System; Version: 6.1.7600.16385; Event ID: 41; Event Source: Microsoft-Windows-Kernel-Power

I would have to think it is the heat issue or some conflict on your system.

Have you tried using MSConfig.exe to keep some start-up applications from running? Maybe if you find the right one, the shutdowns will stop.

I suppose it might also be some type of driver conflict.

I think you may be right about the "heat issue", I saw on another forum that power interruptions could be the cause of the "Event ID: 41. My AMD X2 64 processor runs real hot, but it is a lot cooler than it was on Vista. I saw where I could boost my performance by setting my power options to "High Performance", that is about the time I started to have problems. I just switched back to the "Balanced" setting.

Thanks For Your Help

Oh Yeah, I have cut my startup programs down to a bare minimum, I have also removed all my desktop icons, except for the Recycle Bin. I have 8 quick launch icons in the taskbar, everything else is in the Start Menu.

Shut down and reboot loop

I upgraded my win vista ultimate 32bit to win 7 ultimate 32bit 2 days ago and all has been great till today when it rebooted without warning and no sighs, the screen just went black. When it restart, my pc just swithches it self on and off in a constant loop. Why I dont know. I turn my power supply off for a few secs and when I turn it back on its fine till a sudden reboot following the whole story again.

Im running:
Core I7 920
Intel DX58SO mobo
6Gbz ddr3 Ram
Nvidia GTX275
DVD rom
700w PSU

As of today, mine has been running great, since I set the power setting to "Balanced". . I purposely let it run for 24 hrs, & didn't experience a shutdown. Still waiting to hear from Windows for a "Problem Solution".

It seems I spoke too quickly on my last post, My W-7 is still crashing. I have received solutions from MicroSoft & have tried them to the best of my ability. IE- Installing Drivers, Disabling & Uninstalling Programs, Virus Scans (both local & online), Running Compatibility Checks, & doing a lot of browsing for solutions & cussing.

I made a HUGE mistake by upgrading to this $150.00 fiasco.

Those entries are the result of the problem and not the cause. Is there nothing in the Errors or Warnings area that might lead to a cause?

If it ran good for a couple of days, I would think there was a good possibility an update was causing the problem. If you so desire, remove some of them, especially if there were video drivers involved.

Can you download and burn a copy of the Ubuntu Live DVD? To test your system, you could run that and use graphics or whatever you could to work it. You might want to disconnect your Hard drive just to be safe. I think Ubuntu will run on your processor, but I have not tried it.

I went back to the "Event Viewer" & found this warning close to the time of the shutdowns.

Still happening

I still have random unexpected shut downs, although they have become less frequent because I have started unplugging the psu when not in use. That seems to be giving me some time between random shut downs. Not sure why, but hey.

I couldnt agree more, Im really happy with Win7 I think its great. Its just this little thing with the restarting. If I reinstall the whole thing from the start do I have to install my win vista and then upgrade to win 7 (I have the upgrade pack) or can I install win 7 straight?

You can install Win7 from the upgrade disk w/o installing Vista. There is plenty of guidance in these forums on how to do that. This is also a good instructional link --

Sweet thanks guys

After attempting to "Fix" my W-7 upgrade problems, I finally listened to the advice I found on these forums & did a "Clean Install" & for 2 days it ran great, then I started having the same problem again.
