unexpected shutdown

I'm experiencing unexpected shutdowns of Vista at apparent random times. It
just closes every program and happily turns off and restarts my computer out
of the blue. I haven't been able to make any connection between this and
anything I was doing at the time it happens, in my attempt to understand
what's going on. It has only happened three times so far, two of those times
seem to have started when I attempted to download a file and the third time
it occurred when I started a cmd.exe session.

If anybody has experienced this or similar behaviour in Vista or has any
helpful idea, please respond.
 
Ihave a brand new machine and have experienced unexpected (random) reboots too. The best I can tie it down at present is with Windows Movie Maker when attempting to retrieve DV from a camcorder in 7 or 8 attempts each time there has been a reboot after a period of 2 to 5 minutes.

Probably unrelated, I am experiencing random accessing of the floppy (A:) drive - similar to that which occurs during boot up. So far this accessing has not been associated closely with the rebooting problem other than the frequency of disk access is greater when I am downloading DV.

I am also experiencing unexpected shutdowns. I have an HP Entertainment
laptop that I purchased in Feb of this year. It will randomly shutdown. It
seems at first it happend mostly when I was streaming music/videos or when I
was ripping a CD, but has occured other times as well. My favorite is when
it happens while my maching is in sleep mode. I took it in and the techs
couldn't find any thing wrong. When it starts to shut down I will hear this
obnoxious clicking noise and then a blue screen will appear that says that an
unexpected error had occured. From there my machine will restart and then I
will get the "Windows wasn't shutdown properly" screen. After that all is
well for a few more days. Any suggestions? I am very unhappy about the
situation considering how much I paid for this product.

I've just built a new pc and I'm getting random reboots too. my spec is
as follows...

Vista Ultimate 32bit
Intel Core 2 Duo 2.66GHz
Abit AB9 Pro Motherboard
OCZ 2GB (2 x 1GB) PC2-6400C4 Dual Channel Platinum
BFG GeForce 8800 GTS OC2 320MB
SATA 2 300GB Seagate Barracuda
Corsair HX 620W ATX2.2 PSU

My rig is water cooled and has fans, so I know it's not a temprature
thing. The 620W power supply was £100 and has very good reviews so I've
got more then enough juice. I've swapped the memory sticks with a
friends pc but still it reboots. I've tried different Nvidia drivers
including beta drivers, I've even tried swappig the video card with a
friend who has the same card. I've formatted it several times, tried
installing vista onto a spare 200gig IDE drive but still no joy, I even
flashed my motherboard bios which I think has made the random reboots
less frequent but can't really be too sure.
Being Vista the memory dumps are usless and don't give me any
explination to why it unexpectially shut down. So it could be the
motherboard or cpu? but I'm hoping it's just a vista issue and that the
upcomming release of service pack 1 will help.

Any ideas?

How frequently?

Try booting in safe mode and running some stuff - if it does not reboot
then hardware looks OK and it points to a driver issue...?

It could be temperature - no really it could... check the waterblocks
are all seated correctly and check all the fan's airflow - no reversed fans?

Unplug/remove anything you can from the system and try running as an
absolute minimum sytem... add bits until it starts falling over.

Maybe boot off a Linux Live CD/DVD (Ubuntu/Knoppix etc) and run as a
Linux system... play a few card games and see if it reboots... this will
eliminate all possible Windows OS/driver issues...

If it still reboots in Linux it must be hardware/temperature/memory related.

Can't think of any other approaches for now...

Hmmm....."Problem caused by nProtect GameGuard"

Seems to me the answer is pretty clear. Either remove the software or
contact their software support for assistance in resolving a problem caused
by their software.
