Help me somebody, I'm getting tired of it..I have a 1.6 ghz p4, with everything factory default..I haven't installed new software or hardware that could make it reboot for no reason...it can stay on for 6 hours, 1 day etc...but it always reboots eventually without me doing it..I'd appreciate any help on the matter.

Flakey RAM does this also. Personal experience on this one. More likely to see this with generic RAM, than with good brand like Crucial. If you have more than 1 RAM module, try removing one. See if problem persists. IF so, then swap modules and try again. Where it gets interesting is 3 modules. Sometimes your system will be stable once you get them in the correct sequence.

I built a computer for a friend, and used the generic in it. However, in order to figure things out, I used a memory testing program in burnin mode. To my surprise, the RAM actually stabilized! This was 3 x 128 Mb pc133 sdram dimm modules. I have 3 x 256 Mb pc133 sdram dimms from Crucial in mine and have no trouble.

Hope this info helps you solve your problem.

Im curious as to whether any of these suggestions worked?..I too have a P4 1.6 ghz computer and am experiencing same problem. I have one strip of 256 DDR ram.......Ive done numerous windows re-installs to no avail. Obviously must be a Hardware problem.

I can see I'm not the only one having this kind of problem..
I've a P4 1.7GHz with 256DDR (one strip), a GA-8IEX motherboard..
I'm sure that it's not overheating.. It rebooted after 5 minutes use.. Fans are ok.. Configuration (drivers, etc..) is ok..
I think I'm gonna try with an other strip of DDR.. I'll keep you informed.
If you have any other suggestion, pleeeassee, tell me!
Thanks

I had the same problem with my 850 AMD and tried everything. Turned out that my new hard drive didn't have DMA enabled. It's just a matter of going into the control panel, selecting system, going to the device manager tab, checking the + in front of disk drives, highlighting your hard drive, clicking on properties, going to the settings tab, and checking the enable dma tab. Haven't had a bit of problem with the random rebooting since.

I discovered the cause of the problem when I went to http://www.pcpitstop.com/ and did a full test on my computer. It's free, only takes a few minutes, and it's the best computer analyzing program I've seen.

Hope this helps.

Ric

I HAVE THE ANSWER !!
Actually, Google found it in an instant:
http://www.windows-help.net/WindowsXP/troub-03.html
It is caused by a setting in your computer. When it encounters a problem, it is told to reboot. Go to Control Panel, System, Advanced, Startup and Recovery button SETTINGS. UNCLICK the box for 'Automatically Restart'.
Bingo, fixed.
Hope this helps some of you.
Line fluctuations, (drops in current), can cause it too. Make sure your electrical circuit is not overloaded so that when something kicks in the voltage or current will not drop for a millisecond. Another last choice is replace the power supply with a 300 watt or better quality power supply. Some are just flaky and can cause this.

Good luck

the main cause of the problem is voltage drops... I have seen this problem many times with apartment buildings. having a surge protector or power strip doesn't help either... checking the fans, ram and dma settings are also all great tips... running your computer at http://www.pcpitstop.com/ to find out possible problems is also a great resource... try everything listed above but if no avail then its your voltage. Try moving computer to different plug-in... Problem Solved.!!!

Also,

Check the power supply. To do so start your computer in Safe Mode and then try to shut down. If it doesn't allow you to shut down then its your POWER SUPPLY.

I am just adding more info to my above posting.

Enjoy everyone hope this helps!
