In the almost 5 years ive had my PC only a handful of times, including today have this very strange thing when i boot up and was wondering what it is or if it had a name. so last night i hit shut down and went to bed. Today when i turned it on my CD drive didn't do the self test spin up and in like 1 second i was at the desktop and EVERYTHING was loaded and ready. every icon in the taskbar was loaded all of my desktop icons were there and i hit chrome, BANG opens just like it had already been open. There was literally NO boot time its just instantly up. this has only happened a handful of times and its always confusing when it happens. i know i didn't hit sleep because the power light wasnt flashing and sleep always bring me to the lock screen. I Also have hibernation off. Anyone have an explanation for that?
