xp constant rebooting

http://images.thetechguide.com/forum/public/style_emoticons/<#EMO_DIR#>/sad.gif\' class=\'bbc_emoticon\' alt=\'\' /> We just had cable internet service installed today.  My husband tried it with success then shut off the computer leaving the modem on.  When he turned the computer back on all it will do is continually reboot.  I can get into set up or I can boot from my windows cd but I will have to format my partition to go any further.  Do this mean that everything on my hard drive will be lost?  Do I have a virus?  Everthing worked fine till our new internet service was installed.  Is there anything that could have happened from this new service?

internet connection should not cause constant rebooting of windows. Make sure your antivirus is up to date, run a scan. If clean , download a hijackthis  scan and copy & paste it here. Do not "fix" anything. Just click save log and then copy. There are numerous virus that cause rebooting, so you should eliminate that as a cause first.   .>>> http://www.spywareinfo.com/~merijn/downloads.html .

I had the same problem recently and did not really find out if it was a virus or not Mcafee Virusscan did not find anything. when it happened I tried everything to find out what was causing it and the only thing I could find was when I ran a hard drive diagnostic it said that there was a corrupt sector on the disk after doing a sector repair everything worked fine for a few days then the same thing happened ran the sector repair and it found a corrupt sector again. After all this hassle I reformated the drive and reinstalled xp and now it works fine.

You can get a drive diagnostic program from the hard drive manufactures website if you want to try that before wiping out all your data.

Another thing to do is make sure you use windows update install all updates also make sure you use a good virus scanner and if you are using broadband a firewall is also a must.

my favorite virus scanner is Mcafee and firewall is Zonelarm (Free for personal use)

Hope this info is of use

When your computer reboots, does it show an error window , or box?? Was wondering if it had a "countdown" box showing. Sounds much like a worm.
You can eliminate this as cause by running a free online scan >>>   http://www.trendmicro.com/en/home/us/enterprise.htm  .  Just disable your anti-virus and run the scan {not forgetting to re-enable afterwords}.
It would still be a help to see a hijackthis log to start the process of elimination.
Once Malware/virus is ruled out, you can work on software/hardware issues. Windows rebooting is a common thing with virus, not to say it couldn't be from another cause, just sounds like a worm to me. Might find other things as well. Good luck!

If you are getting a "Remote Procedure Call" or a thirty second warning for shutdown, you are probably infected. W-32 Blaster worm does this , may be others. There is a way to stop the rebooting if the cause is a worm, enough to repair it.

Hope your problems are over {worm}, its easy to remove Blaster/sasser worms.
It might be a good idea to run a HJT log , for your own use. Save a copy and if you run into a problem, you can see what the running process's were---before the problem. Don't forget those M$ updates!. Best of luck

My computer is stuck in the reboot loop that wont go pass a scan of the hard disk.  It loads the blue screen with HP on it then the start of the XP logo then it just reboots... any suggestions... email me at [email protected]

When dealing with HP systems, always remember the F10 key.  Your system restore can fix the problem.

Try starting in safe mode ----tapping F8 key on start
