Dell Vostro 200 random reboots

I have 2 Dell vostro 200's on a small lan  among other Dell's(15 workstations). Both of them suffer from random reboot
that happen once every 1-3 days.

I checked the DELL forums and the issue is listed by quite a few:
http://www.dellcommunity.com/supportforums/board/message?board.id=dim_other&message.id=352203&query.id=60950#M352203

yet no helpful response

I have disabled Automatically Restart under System Failure in System Properties as well as enabled Write event to administrative log before the latest crash. nothing shows up in logs but informative notices and w32time errors which dont seem to be related to the issue.

There is no blue screen, just a full system reboot.
The battery backup is working fine.


They are still under warranty but I'd like to exhaust my possibilities before returning them to the manufacturer.

I'll try and run memtest86 on it today and post an update. For now let me know if you had a similar problem and if so how did u manage it.

Let me know if u got any ideas.

Did you check the outlets where these are plugged in to make sure the voltage is steady? You also need to check if any heavy appliance or malfunctioning equipment is on the same circuit. Running them off a UPS would be one way to do this.

Hi, it could be that your hardware, i.e CPU / GPU is overheating and is causing your laptop to reboot / shutdown. I recommend installing a utility such as CoreTemp to monitor the temperatures of your main components. Let me know what the temperatures are, I had a similar problem with my laptop.
