Windows 7, Random Restarts

[Dav0s]

I have mentioned this in the w7 thread but its really doing my head in now so thought i would make another.

im getting random restarts all the time in windows 7, it never seems to happen when im working on the comp, only when i leave it idle (although this could be coincidence)

it even restarts a lot after it has already restarted and is sitting on the welcome log in screen. i can never really catch it doing it, but im fairly sure it is a BSOD.

when i log back on, i simply get a mesage saying windows has recovered from an unexpected shutdown.

temps are fine, and im clueless as to what it could be. my only guess is maybe it is something to do with the background indexing, since it does it more when idle.

anybody have any ideas?

Well, first we can try to see if it is actually a BSOD to help narrow it down.

Right click Computer > Properties > Advanced system settings > Startup and Recovery Settings > Uncheck "Automatically restart"

Now if it is a BSOD, the computer won't automatically reboot once the crash dump is completed, so you'll be see the BSOD when you get back to your computer and check the error message.

I would imagine it's because the PC is trying to go into a sleep state and you've disabled speedstep/C1E in the BIOS?

For example, if I mistakenly press 'sleep' in Vista, my PC restarts as it cannot sleep.

Worth a punt

First I've heard of that.

Windows usually detects whether or not the computer is able to go into a lower power state mode. Whether it be the S1, S3 or S4 power states are disabled or a driver which cannot support a low power state, the Sleep button should be disabled.

Having SpeedStep or C1E disabled shouldn't affect the PC's low power states at all.

C1E is an enhanced sleep state, so it would affect the sleep mode of the PC

I had that problem but it would instead just shut down. Each motherboard to their own i guess.

Mine would just go to sleep but I couldn't wake it up at all.. Would have to hard power off.

I think you're confusing it with S3. Both C1E (Enhanced Halt State) an EIST is to do with Intel SpeedStep, throttling the CPU.

its too random for that, it can go 3 days without restarting and then do it 3 times in an hour. It seems to do it most on the welcome screen, so i think it must be to do with something w7 does when idle, such as indexing.

that would suggest either a duff hard drive, or a virus somewhere which windows gets stuck on. ill try and turn off indexing and see if that helps.

Considering it is a beta OS afterall, why not try downloading a fresh copy and reinstalling? Perhaps something might have gone wrong with your original copy installation?
