One of my users has a Sony Vaio Laptop and has suddenly started getting the BSOD every morning when he comes in. He stays logged into our Exchange server but has no apps open and leaves it this way overnight. When he comes in the next morning, he moves his mouse to bring it out of screensaver mode, enters his password, briefly sees his Windows session, then receives the BSOD (screenshot attached). It does not happen at any other time during the day, and he does leave it sit frequently throughout the day while doing other things. I've updated all drivers, run checkdisk (no errors), ran antivirus and spyware, turned off all power management (on laptop and NIC card) and still have the same problem. Any suggestions are greatly appreciated!
