Hello again! I have looked around and searched around the boards to see if anyone else has come across this puzzling issue (for me anyway) that I am having. I did see some threads with continous rebooting but I haven't come across anything here or on the intarweb about computers going into a conitnous reboot after microsoft updates: This is my first build. After installing all of the components into the tower, I was given a copy of windows XP pro SP2 from work and I installed it. The computer booted up no problem and no issues noted. I installed the driver to the video card, the motherboard and Norton Anti-Virus. I restarted and rebooted after every installation, no problems noted. Now it was time for the microsoft updates: I puchased the validation key from microsoft, entered the validation key when prompted and downloaded the validation software. I then proceeded to go and download microsoft updates. 59 updates were downloaded to my computer. I then restarted as directed. My computer is now in a critical state of restart and reboot. The computer would begin booting fine...get to the windows load screen, it would hang, the lights on the keyboard would flash, a blue screen would flash with writing on it (no I can't read what is written because the flash is too fast) and then my computer would restart. Over and Over and Over. I cannot access SAFE mode, it continues to go into a constant state of reboot. I really don't want to reformat and reinstall the OS again. Mainly because the validation software was downloaded ...and there is no possibility of getting to a restore point because I can't access safe mode. Hitting the windows key and pause break key to bring up the system properties to turn off the constant reboot does not work either. I still haven't received my On-line Product Key from microsoft and my CDs, which said would be shipped in 2-4 weeks, have been backordered . The only thing things downloaded onto the computer prior to the microsoft updates were the updated drivers for the graphics card, the Mobo and Norton Antivirus. The computer was restarted after every install and on problems noted. ...and the best part, because it's a copy of windows xp pro sp2, microsoft wants to charge me $99.00 tech support fee. Boy did I make the wrong decision on what OS to install. -EDIT- The worst part is that I have a newly purchased BF2142 currently burning a hole on my desk. If we can get this figured out, those of you that have the game can join me in game and shoot me full of holes for the double post!
