Since normal boot up isn't working, see if the system will boot up into XP's Safe Mode.
Turn the system on and during the BIOS posts messages, (the "2005 American Megatrends messages), but before the XP logo displays, start pressing the F8 key gently once a second. After a while you should see a list of options with "Safe Mode" at the top. If that is highlighted, press the Enter key on the keyboard. If it is not highlighted, use the keyboard arrow keys to highlight it.
This is XP's Safe Mode, a diagnostic mode that can sometimes help to sort out problems. The display is larger and in basic resolution because only default drivers are installed, and there is no Desktop background image.
If Windows manages to load in this mode, you can then try to carry out a System Restore to return the system to where it was before the updates. Or you can uninstall the problem update.
I hope that helps.
Hey everybody, I'm brand new to this forum so if i have broken any of the rules with making this discussion, I apologize in advance. Yesterday, I was prompted by the "Windows Update" service that I had a bunch of updates that needed to be made. I would say that there were about 8 or 9 different services in the update that needed to be upgraded. I went along with the procedure, and every time one service in the list was updated, I would be asked to restart now or later. For every one of them, I clicked "restart now" This happened all the way until the last service was updated, which seemed to start the problem. I have no idea what happened after that, but when it came time for the computer to restart, it failed! A black screen would come up saying, "2005...American Megatrends" for a short 3-5 seconds, and then the windows xp logo would come up as if it were booting up as usual. However, every time the windows screen is loaded, the whole process would restart and loop continuously. I have no idea what happened and I really hope I did not lose any data or would have to in the process of fixing my problem. I would try to put up some screenshots of the problem or a video from my phone if possible. Thank you for your attention and help!
