I have a dell xps gen 2, just in the last few days I have been having a problem with it freezing when windows is starting up. It happens just after it loads into windows. The computer will freeze for about 20 seconds, the strange part is that it only happen if the computer plugged into the wall, if it running off the battery this doesn't happen. If I boot into safe mode it doesn't freeze at all even if plugged in. I have tried another A/C Adapter for my computer but the same thing happened.
