I've searched the very depths of Google, and I haven't found a real solution to this problem, but at least I know I'm not the only one. My computer will randomly shut down for no reason; sometimes I'm typing in Word, sometimes I'm using the internet - there seems to be no relation to the program I'm using to the random shutdown. I updated my BIOS, since that was recommended by a friend experiencing the same problem, but no dice. Anyone have a solution to this? By the way, I'm running Windows 7 Professional. I just recently upgraded from XP, where this issue never occurred. This has only started since the upgrade. EDIT: Okay, well, I just found some sort of continuity with all of this. I went to my event log and found that something called "EventLog" and "Kernel-Power" that happened with all my random shutdowns. The Kernel-Power would happen first, then the EventLog within a minute (or less) and poof, no more power. The Kernel-Power says that: "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." But I know this isn't right, because this is a desktop with a constant power supply - no chance of the power getting knocked loose. Can anyone help me from here now that I've provided more info? Thanks for any help!
