Spyware, adwear, virus of some kind. If your computer is acting up honestly you probably should consider backing everything up and reformatting cause really, once something is on there if your antivirus is broken, can be a pain getting one installed. and it may never run the same till its cleaned out. Once a year thats what i suggest. 3 hours can save you hours of head banging in the long run.. Anyway go to msconfig click on diagnostic startup, apply, restart. This is going to turn off all the colours and only run esentials. go to and run a free online virus scan. Check your hdd, make sure its not the issue. go to run, type in cmd hit ok, type in chkdsk -r -f and restart. clear out your temps by going to my computer, right click C, properties, disk cleanup and check all the boxes. Finally right click my computer, properties, advanced. something there that says restart on error kernel dump click dropdown and change that to not restart

1) often this is caused by automatic windows updates: it installs an update that requires a reboot and will do it immediately - simply ignoring that some user is logged on currently!

with windows xp professional you can use gpedit.msc - there's a policy that allows you to disable this kind of behaviour.
you need to enable the policy “No auto-restart for scheduled Automatic Update installation".

however, windows xp home does not include gpedit.msc.
there's another solution: re-configure the automatic updates to "automatically download but let me chose when to install".
the title is a bit misleading. even if you do not manually chose to install the updates they will be installed when shutting down windows.

for full details see:

2) in case the automatic reboot is caused by some fatal error:
disable the automatic restart (as already suggested by kenross). you will also find some according entries in the system event log.

3) sporadic reboots may also be caused by overheating due to poor system cooling.

4) last but not least you should ensure that you have all required microsoft patches. you need to manually go to the following url, once:
this is to install the component "microsoft update" on top of "windows update".


for complete analysis it would be important to know:
- did those restarts start occuring just recently or has it always been like this at your computer?
- how often does it occur? once a week? twice a day?
