I have a Vista Home Premium x64 SP2, Toshiba Satellite A305 with 4GB of RAM and integrated video/sound, i have 2 hard drives each with roughly 250GB of space, my CPU is Intel(R) Core(TM)2 Duo CPU T5750 @ 2.00GHz
i left my laptop on overnight with out an Internet connection (in case it decided to restart or something the network i am on won't allow the computer to shut down successfully if it is on the network, it just freezes) and when i got on the next day every window that was already open that i clicked on froze, and i clicked the start button and the start window only partially came up and i got a message that explorer.exe had crashed. so i held the power button until it died.
next when i logged into my user name i got a black screen, nothing was starting, when i brought up task manager it showed 10 processes in the list but 87 were active and it was using 100% CPU, after leaving it on for 5 hours with the only progress being my task-bar popping up but my cursor being the busy icon when i roll over it i held the power button down again.
next i successfully booted into safe-mode and ran a system restore witch took 2 hours, i then booted into vista, it took about 1 hour to boot and it looked like it had booted, but everything just started freezing again, so i ran sfc in safe-mode witch did not make things better at all!
