Recently purchased a copy of Win 7 Pro x64 to replace my now very old, but well-loved 32 bit XP Pro. Running on a system with a lot of parts "7 ready", I expected an easy transition. However, the BSODs cometh! The one that I am getting comes with the message "A Clock interrupt was not received on a secondary processor within the allocated time interval." The only posts I have been able to find about this specific BSOD are all a couple years old. It happens in normal and safe modes. If it doesn't crash immediately after loading Windows, it will within about one minute of me logging on. In safe mode I can get maybe about 10 mins if I am lucky. It has become impossible to fully update the computer with this happening. And yes, a lot of the drivers may be out of date, as this information was taken from a fresh install, which I tried to no avail (after Win 7 refused to install 4 or 5 times). However, I was getting these from the first install I did of Win 7, which went well with all pertinent updates, and then of course I got the lovely BSODs. Any ideas?
