XP Pro in reboot loop

April 14, 2005 at 21:19:17
Specs: XP PRO, 2.7 Cel / 1GB ULTRA PC270
ok...I have Windows XP Pro with service pack two and all the latest microsoft updates. My pc is behind a Router and has three software firewalls a registry monitor running. I also run norton antivirus, Spybot S&D 1.3, AND Ad-Aware SE Personal. About a month ago my computer went crazy and I did a clean install of XP. Two weeks ago the same pc went into an endless reboot loop at start-up and after a lot of troubleshooting I gave in and reinstalled XP....AGAIN. Now a mere 12 days later I am faced with what appears to be exactly the same problem. I cannot get into windows xp, it boots to the xp splash screen, takes a second, flashes a BSOD(too fast to read, then reboots.

I've gone through all of the 10 pages listed here....and this is what I've tried: I tried safe mode..same effect(reboots after agp440); I tried using recovery console to disable agp440..same effect; I tried overwriting ntdetect.com and ntldr; I tried fixboot and fixmbr; I tried doing a repair install and I even swapped the video card. None of this has made ANY difference. I have not installed any new progams or windows updates in the last few of days. All of the hardware in this pc is less than 1 year old, the PSU and the HDD are 1 month old(replaced when pc went crazy the first time) everything else is about 9 months old. I'm really don't feel like reinstalling windows just to have to go through all this crap again in two weeks so...please help! and keep in mind I cannot get into xp even through safe mode ;)
thanks everyone.

It seems to me that it is a driver file that keeps getting corrupted after the install. But it could also be hardware problem. Sorry, but just because something is new, doesn't mean that it is working properly. We are talking electronics and just the touch of a shock from static electricity can kill your computer.
Try this:
remove all but the minimum amount of hardware from your machine....1 stick of ram
just your hdd and the mobo and graphics card. Everything else is not needed to run your system. Boot up and see what happens. Even if it fails the first time switch to the other stick of ram and try again.
If it boots on the 2nd try then you will know that your ram is conflicting with something or just went bad. If it startes then systematically install each piece of hardware one piece at a time and reboot till you find the culprit that is causing you the problem. If it fails to reboot at all then it is something to do with either windows itself or your hdd has some bad clucters that keep failing.
There is one other issue that you may look for. Overheating....make sure the fan on the cpu is operating and is not clogged up with dust.
let us know if anything helps or not.

swim with the current;
in matters of principle,

3 Software firewalls?

In XPSP2 there is a new option in the dialog where you access safemode.

Just hit f8 before you see the XP splash with the scrolling logo and select

Disable automatic restart on system failure

That way you will be able to see the blue screen and which driver is causing the problem.

I'm not sure about this but it seems like it could be a result of having 3 software firewalls installed?

They could be conflicting with one another?

Do you really need 3? Seems a little unecessary...

go to the recovery console and run chkdsk /r and if that doesnt get you back in try article 307545 or a repair install ,the poster telling you to strip down to just the basic needed to boot hardware is right on.

I tried removing additional hardware with no luck....I'm hesitant to believe it's a hardware issue with acception to the possible HDD failure. I don't think it's an overheating issue either....I let it sit for about 4 hours before I came home from work and powered it back up; unless maybe the over heated cpu could have corrupted files during operation. all of my fans and the inside of the computer are very clean with no significant dust build up(it's new).

I don't appear to have the option in the advanced boot menu(F8) to disable automatic restarts on system failure. I just started using the three firewalls. Before the last occurrence of this problem I only used Zone Alarm, but after getting a nasty little hijacker(about blank) and reinstalling windows I enabled windows firewall and installed Norton Personal Firewall 2002. I don't think it's an issue with the firewalls because I've never had a problem with ZA and this problem occurred once before I installed the other two firewalls.

I've already run chkdsk /r and tried a repair install with no luck....I'll try the registry fix mentioned in 307545...if that doesn't help, I think I'll try a different HDD.

Thanks for the help and if you can think of anything else please let me know. :D

Dude, were you able to figure this thing out? I'm having the *exact* same problem, but can't seem to find a solution to disable auto-reboot from repair mode or anything else.
Any hints are appreciated!

I had a similar problem - stuck in reboot loop, tried to do a clean install of XP, couldn't get it to take. Went through the hardware bit piece by piece, nothing changed. Put in a different hard drive, was able to install XP Pro, and about 2 weeks later it was stuck in the reboot loop again. This time I was able to get into safe mode and uninstall Service Pack 2. My computer works great now. Even the weird humming and growling has stopped.
If you can't even get into safe mode, you may have to reinstall XP again. Do all the Windows updates, but do NOT install Service Pack 2. I've heard a number of people have had problems with this service pack.
Good luck, I hope this helps and you get things working.

have similar problem except when I swap the hard drive from an HP machine into a generic one I built, it works fine. Place it back in the HP machine and it reboots in loops. Microsoft is aware of the problem according to 'http:\support.microsoft.com\875350\'. THey seem to believe its a software issue but according to my specific experience there might be a software component issue or some sort of a conflict. Will post if I find more info.

I've had the same problem with two different computers in the last week! It only starts after I install the latest updates from Microsoft. It works fine with SP2, until I install the latest updates. Still looking for a fix.

If a hard drive workd fine when put into one computer, but you get reboots when you put it in the HP, then the HP may need a Power Supply upgrade. HP is notorious for running HOT and putting in weak power supplies. I only use Antec True 'CONTROL' 550watt PSu's on my 'puters. Comes with a module that lets you set the fan speed and 3 power settings. Install Motherboard Monitor 5 or any similar proggies and keep track of heat, power, and fan speeds.
Hope this can be of some help to someone.
