Can't Log On To Desktop XP keeps rebooting

[SamuraiWarrior]

My daughter told me her system keeps on rebooting everytime she tries to log on to her desktop. So I went to see what was up. When you start the PC and get to the windows logon screen and go no further the PC will run normally.

I then booted into safe mode without any problems and surfed the net with no problems. I figured it was something she did by playing with her system settings. I also did a online virus scan with trend micro and had no issues. So then I added my self as a administrator and then deleted her user name and deleted all her files. When I rebooted again everything was fine. I next did another virus scan with my AVG and it again checked out fine. After a while I shut down the system. When she came home and turned it on again, again it was having problems.

I'm doing a test of the memory using doc memory and so far it is going good. I also checked to make sure nothing was over heating and that all fans are spining.

Specs areASUS P4G8X Intel 2.4 GHZ Celeron 256mb Pc/2100 (2x128) Crucial DDR memory

Asus V860 Nvidia 64MB ddr video card

Maxtor 40 GB 5400RPM hard drive

In the Advanced tab, "Startup and Recovery", hit the Settings button.
Take the tick mark OUT of "Automatic Restart".

See what the error REALLY says.

Thanks I will post my reply. did what you said and quess what no error message and it is at the desktop. I will do a couple of reboots to see what happens

Here is the error message

***STOP: 0x0000008E (0Xc0000005,0X8051AF74,0XF9CA0264,000000000)

[reboot]

Go into Control Panel, Power Options, Hibernate tab, and make sure it's disabled.
Make sure you have all the updates from MS, specially the SP1a.
Get a docmem and run it, from www.simmtester.com
Could be a bad module.
If you're running Trend PC-Cillin, remove it and see if the error persists.

Thanks I started to run doc mem but stoped because of work. I took out each module and tested them one at a time in the same pc and have not had any issues. Can one still be bad and not work well with the other??

[reboot]

It's possible, however, I think it's probably another issue.
Could be anything from hardware conflicts, corrupt device driver, overheated component, bad memory access by some startup program...
Check the memory using this:http://oca.microsoft.com/en/windiag.asp
Take the case off, and make sure all fans/vents are totally clean for max airflow.
Consider having your power supply tested as well. Fluctuations in power can cause this.

I did notice that the hardware monitor keeps telling me it found a problem and when I go into bios it say power fan is runing around 1750 to 1795 and it is in red. I don't know what that is, but when it turns a blue color everything is fine. I also found a link that says it is most likely video driver related. I uninstalled the drive in safe mode and rebooted and the screen stoped flickering and the system didn't crash anymore. So I'm downloading new updates from ASUS for the Nvidia card I have installed. If all goes will than fine I will post results.

It apperars that after talking with tech support over at Crucial and giving the tech the first set of digits, he said it was a driver and that iti pointed to the video card.

What I did was removed one stick of ram and booted and everything was fine. Then I removed the first one and put in the second and again no issues. But when you stick both back in errors again. I did however test both sticks with doc memory and they checkout ok.

I booted in to safe mode and revmoved the video drivers and no problems. I then went to Asus and downloaded the updated drivers. But when tried to install I got a error message, saying to uninstall the device drivers. I did and still had problems. So I then reinstalled the old one to see if that would work NOPE, XP crashed again. After having no luck installing the new one a couple of times I called Asus support and what a dissapointment. I had to go on line fill out a trouble report form, then when it gave me a number, I then called support. After waiting on the phone for 15min a rep came on and said all support were busy. He asked for my name and phone number, and said they would get back to me. well I haven't heard yet??? I thought Dell was bad.

[reboot]

Boot to safe mode, remove all video drivers, set video to 640x480, standard VGA.
Restart.
Get the proper GeForce driver (WHQL certified) for your video card.
Install it.
