PC Randomly shuts down

Hewlett-packard / A1709N
January 27, 2009 at 12:02:30
Specs: Vista Home Premium 32 bit, Athlon 64x2 5000+ / 3GB
It rarely happens while im using it, I'll walk into the room and it'll be off when I just got off it 5 min ago. It does fine under stress and everything, seems to do it more while its idle. Could it be power issues from the outlet? Or even the psu? Psu isn't very old, 6 months. 500w xclio

Check to see if it's going into 'System Standby', Display Properties > Screensaver > Power.

FWIW to XP users: When you click on the 'Command Prompt' you are just causing the 'Command prompt' to be displayed. This prompt gives you access to NTVDM.EXE, the 'NT Virtual DOS Manager'.

Just wondering if you solved this problem, I have 5 computers that are doing the same thing, except that there is a window (winXP Pro) that pops up before it shuts down notifying the user that it is shutting down.
I haven't witnessed it because i work for a School District and I am getting the info from the teacher in the classroom. She says that it happens randomly while using the computer or is just idle. I am wondering
if the power could be the problem because we have more than 35 of these computers at this school alone and this room is the only one that has complained about this.

what exactly does the popup window say? it sounds possible that someone in IT may be initiating these reboots.

save your stuff and close your apps. go to the run line and type:

shutdown -r -t 30

that will reboot your PC after 30 seconds. Does the popup window you see match the other one the teacher is getting at school?

are the PCs plugged into a surge protector?

what about a battery backup or "line contitioner?" A surge protector will protect against sudden INCREASES in power ("spikes"), but not against "dirty" power or "brown-outs," where SOME power is still flowing but not the minimum required to run the PC. This will cause reboots and damage hardware, but you typically wouldn't get a windows popup in this situation, the system would just crash...

still, it might be worth looking into. i know most school buildings were built sometime prior to 1654 and have yet to receive the funding to catch up on little things like plumbing, electrical wiring, or chem books with periodic tables past element number 99 (there's something like 116 known elements now).

I am the IT for this school and have used the SHUTDOWN -R -T sequence but not in this class recenlty. I don't know what the window says only what is told to me by the teacher something to the affect of "Windows is shutting down" I recently took one cpu to my office and left it on for 4 days straight without a shutdown. That's why i suspect it could be power accept Windows would not "know" about that unless there was a backup power supply. These computers are all connected to a surge protector, here is the strange thing that i didn't mention before there is 6 computers in the classroom 5 HP DC7800s and 1 Dell Optiplex 745, the Teacher said the problem was exclusive to the HP's but one time the Dell also went Shutdown (not reboot they shutdown and do not reboot). I have been in the IT for 8+ years here this is got to be one of the strangest problems i ever had.
FYI the computer that i brought to my desk that didn't fail before i returned to the classroom i re-imaged then returned it back to the classroom. Today the teacher said they all (HP DC7800 not the DEll) shutdown.
Besides the image and brand the only thing these computers have in common is some Education software called Imagine Learning, this school is the only school that has this software (7 schools approx 350 HPDc7800).
Heck my computer is an HPdc7800 and have not seen this problem.
Sorry for the long post but i have usually have been able to figure out issues or find someone that has been thru the same thing.
One more thing HP has been having problems with the Power Bricks for these DC7800's i have had to swapp out at least 10 of them within 7 months after install, i haven't been able to get HP to say anything about this though.
Thanks for your reply and interest.

it sounds like the problem is most common on the HPs, and only in a certain room?

if it's in the budget you might try installing a battery backup / line conditioner on one of the HPs in the room having the trouble. You should be able to find a decent one for around $100. If the HP does not crash with a line conditioner when the other ones do, it probably has something to do with the electrical in that room.

it is a bit weird that the HPs would crash and the Dell wouldn't, but you mention having trouble with their power bricks in the past - maybe the Dell PSU is more tolerant to dirty power than the HP PSUs? (i'm grasping at straws at this point, but i've seen weirder things...)

Good idea with the backup on one machine, we might have one that just needs a replacement battery.
I guess i am giving the Teacher the benefit of the doubt and have been left only with what she is telling me. I haven't been able to re-create the problem I guess for me frustrated is a better word than weird.

Thanks,

I'll keep you posted on the solution if there is one. (I like closure and solutions)
