It also sounds like you have a power supply problem. My comptuer randomly reboots since i added a 2nd hard drive, because the crappy 145 watt PS in my comptuer can't handle all my extra stuff
Also, make sure the power cables are plugged in firmly.
Another reason is that you have auto reboot on blue screen. If a box comes up after it reboots saying the system has recovered from a fatal error, it means that the system BSODed and automatically did a memory dump and rebooted. Check event log for details (look for red X)
Since Microsoft has worked so hard to make this version "the most stable ever," then this tweak is not needed. However, I am fairly sure that they have not perfected millions of lines of code in less than a year. Below you will discover how to turn the auto reboot feature on and off. This allows your computer to instantly reboot upon a system fault. (The blue screen)
Navigate to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > CrashControl
Select AutoReboot from the list on the right.
Right on it and select Modify.
Change the value to 0 to disable and 1 to enable.
Reboot your computer
My putter was re-starting for no reason too... found out it was a blue screen error....... Did the fix and XP let me see the error so I could fix the problem !!!
I beleave that this error is from XP not shutting down right. It stores temp files in these folder that it reads at boot. If the computer restart with-out proper shut-down then the temp files get corrupt and boom the error on boot-up.
Thats just what I think !!!!
Had this happen to me when my putter was not shut-down right !!
But we need to get the memory problem fixed or this will keep happening...
There's a search box on the upper left, type in STOP: 0x0000007F. This brings up about 20 articles... start reading. Looks like a hardware issue for sure, but with all the articles on this particular code and not knowing more about your system it's hard for an outsider to pinpoint for you.
My system was working fine, and all of a sudden I would get the same "STOP: 0x0000007F" errors and could not boot into Windows even in safe mode. Tore my PC apart, and got it down to the vid card and one stick of memory. Same thing. Swapped the DDR stick with my other one and it has worked fine since. My other Crucial PC2100 DDR stick has gone bad. Definately hardware. Although, my event viewer always shows acpi errors after rebooting. Mobo is Abit KG7 with 5W BIOS. Anyone heard anything on the acpi thing in XP?
Yeah...mine will run fine as well...aside from the RAM issue. The only acpi error reports are when I reboot my computer. I have flashed to the latest BIOS by ABIT. Many point the finger to XP for this.
Man this is almost Identical to my problems...(You might remember Forum experts!). The restarts happended on my computer. It seems that the general consensus is that it is an insufficient PSU causing your problems.....BUT as i said ive had the same problems and i have a AMD approved 300w PSU.
But fingers crossed i thnik i have sorted the problem by striping the PC down to the bare bones and reinstalled XP and then one by one installed all of my hardware.
DO you thnik it could of been a loose PCI card or DDR module???
I stripped mine down to bare bones and it still happend with one of my DDR sticks. I switched it out for the other stick and all was well. My PS is an Enermax 431. It has been running for about 4 months fine. PS is fine and my voltage still read fine. Mine was definately the RAM.
