t could be several things that cause your computer to reboot on its own. Here's a few to check out....\n\n1. It could be a virus. Do you have updated anti-virus software running on your computer? Do you notice anything unusual running on your PC?\n\n2. Your PC could be overheating. Does your PC have adequate ventilation? Does it have very little dust on the inside? Is the Processor getting too warm?\n\n3. It could be misconfigurations. Meaning your PC may be blue screening (without you seeing it). Windows XP is notorious for blue screening and rebooting right away before you even know what happened. Did you install something recently that could be uninstalled? Did you add a new hardware component that's not functioning properly?\n\nHope this helps out a little....

It is possibly overheating. Check the fan. Check power supply, it could be going out. If not:\nYou probably need to reorder your BIOS by hitting del on startup. If you dont know how to do this please dont try, get help first.\nHere is a search of this problem, choose one of these forums that seems most similar to your system and ask them. They should be able to help. Its hard to troubleshoot a problem on Yahoo Answers as we cannot easily have continuous dialogue.\n\nGood Luck!\nhttp://www.google.com/search?hl=en&q=computer+restarting+over+and+over

Your machine is lacking in memory.\n\nYou are running too many memory resident programs and/or you have more windows open (could be browser windows or other applications). \n\nReduce the active load on your machine.\n\nIf that does not help, then restart, may be a program is stuck in a loop somewhere.\n\nIf even that does not help, run an anti-virus, may be you have avirus.\n\nIf that also does not help, try reinstalling the operating system.\n\nIn case nothing of the above works, get a new machine with better specs.

It is shutting down. Your computer just takes a long time to shut down. Maybe it has many processes active or you need to cleanup your files.

There could be a lot of reasons for this. It may be that you need to \nreinstall windows.or it could be that there is an issue with your power supply or your motherboard could be overheating.\nI would try reinstalling the operating system first and take it from there.

I agree with Hot hondagirl, some programs require a restart post donwload before they work properly.  But you may have something else going on.  I would, just to be thorough, check your PC for spyware adware and viruses.  Free tools can be found at www.download.com\nI suggest spybot search and destroy, adaware personal Se b Lavasoft, and spyware blaster from java cool software.\n\nAnd if you have recently reformated or made any major changes to your PC, I would suggest getting the latest updates for your OS or running a repair.  Or check your browser install, maybe you need to update that or reinstall.

causes your laptop to completly reboot?! \n\nThat might be a diff problem. run spyware and virus scans with fully updated programs. Also, check to make sure you have all running updated drivers. Check the event log, right click My computer, click Manage, and go to event viewer. Check out the System part in the event viewer, see if there are any major errors. \n\ngl !

Random reboots/crashes/freezes could be due to several reasons,  including RAM, hardware issues, etc., but rather than waste everyone's time playing "20 question" type guessing games, just do the following and post back with the info so that we can narrow it down some.\n\nGo to control panel/ system / advanced Tab/ startup and recovery box/ settings button/ sytem failure  and uncheck  "restart on system failure" ( take the check out of automatically restart box )   ,   and check the Write a system event, and the Admin alert boxes (check "send admin alert").     This will force a BSOD on the next crash (freezes/restarts =  crashing) that posts the Stop Error Code.     On the next crash write down the exact Stop Error Code and post that exact error  here back on this thread.  \n Also go to your device manager (devmgmt.msc) and check the properties  and look for anything suspicious and check that the settings are where they should be.  \n      \n  Check\n\n1.  Overheating(Open the case and check to see how much dust has collected inside it, and  if there is alot of dust get a can of compressed air and blow the dust out and clean out all dust bunnies, etc. on the heatsink/;fan combo,etc.; and be sure all the fans are spinning and properly functioning )  \n\n2.   Poor power supply   (weak power supply or noisey / dirty electricity) \n\n3.  Bad driver or drivers not updated,  or a device conflict.   Pull the connectors and push them back on. Reseat all of the cards. RightClick - my comp/properties/select the hardware tab/click device manager/see if there are any "!" next to anything.   Try updating the drivers from the manufacturers' websites.\n\n\n4.    Not enough memory or bad Ram.   Missmatched ram or a bad stick of ram  will cause this also.       (Run Memtest86: = http://www.memtest.org and  \n  FREE RAM Diagnostic Tool. -  CST Inc.s DOS based DocMemory  =  http://bucarotechelp.com/computers/default.asp )   .\nYou might need to add more Ram.\n\n5.   Could be  IRQ conflict  \n\n6.  Perhaps the CMOS battery on the motherboard is going bad and needs to be  replaced. Check it to be sure.\nAlso check your pc clock's time and day, to be sure it is set correctly. \n\n7.   Hard drive could be failing.       \n\n8    Right click desktop/properties/screen saver/Power/Hibernate tab ,and make sure  hibernation is not enabled, and cleann out your   Cache & Cookies & Temporary Internet Files and Folder: = http://www.coloarts.state.co.us/cleanFiles.asp\n\n9.   Make sure you have updated all programs and hadrdware.\n\n10.   Motheboard short (loose screw, misplaced mounting standoff ,  etc.) ?\n\n (Note: Will it boot into   Safe Mode?  Hit F8 or F5  right after the BIOS screen to get boot options.  Does it also happen in safe mode?)
