I also forgot to mention that I tried to go online with both the automatic time synchronizing and auto-updates disabled but it still cut off with the same error code.
I would have reinstalled XP but she could not find the back up disks.
This one has me stumped. I got a HP Pavilion 516x computer (a little over 3 years old I think) from my 'god-daughter' that looks like it had never been updated, defragged or scanned for viruses. Of course she didn't think anything about it until it finally got to the point of not working at all. It has a 2.4GHz processor with 512MB of ram and running Windows XP home.
It had either the Sassser worm or something because it was restarting over and over again but I figured out how to stop it by just disconnecting the Ethernet cable. Then I was able to boot it up and clean it out a bit. I used a jump drive to load it with Ad-aware and scanned it a few times with that and the anti-spy ware and antivirus that was installed with Yahoo DSL.
Them after a lot of tinkering around, I loaded SP2, and a lot of other updates plus Windows Defender and McAfee Antivirus, but I still have a problem with it wanting to reboot quite often. I disabled the reboot feature so it would just stop at the blue screen of death with the Error Code. It gave me a 0X0000007E code and I looked it up to be something about a driver problem but even after I updated a few of the drivers it still does the same, with the same error code.
The drivers I updated where the Intel(R) 82845G/GL/GE/PE/GV Graphics Controller, Realtek AC'97 Audio, Realtek RTL8139/810x Family Fast Ethernet NIC, and I updated the BIOS.
Now the computer seems to load and run just fine. I can keep it attached to my home network where it can share files and communicate with my other computers with no problem. But as soon as I enable my DSL modem and try to access the internet, it will still turn off with the same error code coming up. It does allow me to go online for a short while, and a few times it did it for quite a while without clicking off, allowing me to get a few more updates and know that everything can function correctly, but I still can not boot it up if the Ethernet cable is connected or expect to connect to the internet every time without it shutting off again.
The time it seems to shut off is either right away when I first get connected to the internet, or if I try to go to any Microsoft website. I thought maybe this was because there is something trying to check for new updates that is triggered by going to Microsoft.
