W32/IRCbot.worm is a medium risk worm for home users. You can be infected simply by going online. Once infected, your computer may restart continuously. http://us.mcafee.com/virusInfo/default.asp?id=description&virus_k=135491

This could be a cooling issue, check your fans and dust out your system. I saw one system the other day that did this because of the massive amount of dust, even though the fans were still turning. \nAlso try starting the computer in safe mode and see if it works then or locks up without restarting. A bad XP install will cause this sort of action. Sometimes there is a bios option that tells the system to restart on error, you can turn this off to help diagnose the problem.

Make sure there are no floppies or cds in the computer when it is booting up.  Otherwise your hard drive may be in trouble.

OK you do not provide a lot of information as to your system.\n\nFirst boot into safe mode by pressing the F8 key once the computer starts to boot. Choose command prompt only and see if it still shuts down.  If it does not that is good.  if it still shuts down, open the case and remove any expansion cards you may have installed except for the video card iof you have one.  Remove and put back in the memeory.  Look for lots of dust in the system also if there is a lot of dust then take the system outside and blow all the dust out with either canned air or an air compessor use care  not to blow too hard.  Pay attention to the poser supply.  After cleaning the computer out and reseating/removing all of the cards and memory restart the computer in safe mode and see if it stays on.  If so it is probably fixed.\n\nIf it still shuts down it is probably a bad power supply or the processor is overheating.  if you feel confident you can reseat the processor and replace the power supply.  If not ask the local computer nerd at work or a friend for help.\n\n\nIf the computer still shuts down it is probably something major.\n\n\nTo make sure a virus is not the problem just disconnect the power cable to the hard drive and boot the system.  if it will stay on but shuts down with the drive booting then there is a good chance you have a virus.  Do you have antivirus software installed and up to date?\n\nhave you tried system restore going back a week or so?\n\nRemoving a virus is a whole different question

Right click on My Computer icon> properties>Click on Advance Tab>Down at the bottom find Start up and System Recovery> hit the settings> uncheck---Under System Failure----Automatically Restart..\nThat should take care of it temporarily.\nU might wanna rebuilt your PC from scratch...U might have some other serious issues which is causing it.\nGood Luck.

The cmos battery shouldn't stop the computer from booting, it'll just boot with default settings each time. If you have a totally dead box check the power supply first. You should always at least get a fan whirring or something.

Hard reset.\nReformat the cpu and start over.\n(back up any documents you'd like).\n\nthat's the easiest, least ocmplicated way.

Could be that your CPU fan is not running or dirty, the CPU is over heating and causing the PC to reboot.\n\nYour Hard Drive is about too die.\n\nA sticking key on your keyboard.\n\nBad BIOS .\n\nGood luck, caned air and a vac helps your PC stay cool.\n\nOther then that I would run disk check and de frag.\n\nAlso in my old place this guys CB radio used to make my PC reboot.\n\nOk how abou a grounded out USB, that will do it, unplug any USB things you have and see it it does it.\n\nAlso make sure the USB female slots are not grounded to the case.\n\nA screw can be wedged between the Mother Board and the case.
