So, my friend is currently running Windows 7, without any updates. Whenever he boots up his computer, it is fine for five minutes, but then crashes and gives a blue screen of death. I looked up the error code, which is 0x0000003B, which is apparently something to do with IEEE 1394, which is Firewire. To make matters worse, I tried using a hotfix from Microsoft, but I can't get it to install before the machine blue screens. It doesn't blue screen in safe mode, but I also can't install the hotfix in safe mode, for what ever reason. Does anyone have any idea?
