Today we downloaded the new updates from Microsoft for Windows 2000. After the download, we went to restart. The computer booted up to the Windows 2000 screen then it went to blue and the computer restarted again. This continues until you turn off the computer. If you turn the computer back on it starts all over again. We kept hitting the f8 trying to get into safe mode, but it would not work. We then tried to boot from the CD but it would not boot, just continued in the loop. Then we made floppies to boot from. We put the floppies in and it loaded disk 1, then we put disk 2 in but it wouldn't recognize input from the keyboard when we hit the enter key. So we then turned off the computer, unplugged the mouse then turned the computer back on. Finally it recognized the enter key and we were able to load all disk. We selected emergency repair and it checked our devices then it said it would restart. So it restarted then got to the Windows 2000 screen, the blank blue screen, and cycled off and on again and started the boot loop all over. During the next cycle, we were able to get it to recognize the f8 and so we selected Safe Mode and basically would not come up in safe mode either, just cycled off and on again to reboot. It is an old computer (had it since 1998). Right now we have taken out the power supply and plan on trying to get a cheap replacement to see if that is the problem. Other thought is perhaps it might be the video card. We are thinking that perhaps it is no longer support with the windows updates that just came down....it is an old ATI that has a television receiver in it. Any other ideas as to what might be the problem? It is driving me bonkers :bounce: Thanks in advance for any advice you have to offer!
