Please, please, please someone answer this! My computer just did this--the exact same symptoms. No new software, no unusual use. It crashed, so I restarted, and now it's frozen on the blue screen that usually flashes just before loading.
I've tried letting it sit, I've tried safe mode, I've checked to make sure the keyboard's functioning, since it isn't accepting any commands whatsoever.
I've searched all over the internet to no avail, and this is the ONLY place I've seen something about a problem similar to mine .. and it's got no responses! Help!
