Oh I know that feeling so well. I have this "waking up at 6 AM" school schedule and even though I always swear to myself to go to bed at 11 o'clock and fall asleep half an hour later, I always find myself counting sheep for hours. Such a frustrating feeling.
I used to drink an insomnia tea just after school started and it worked for a couple of weeks, I fell asleep easier, but then the body got used to it I think and it got back to usual.
It's just meh.
That happened hundreds of times to me. I've started thinking my computer is kinda PMSy, cause, every two months or so, it needs to have one "crashing week", and after a few days of trouble, it keeps on working as if nothing. *shrugs*
Also, in that situation, it usually turns on after I unplug it, plug it back in like half an hour and try again.
Hope it gets fixed, let us know.
/edit: I just remembered something that makes me laugh every time and I wanted to share it with you guys:
In a moment of blind stupor, I thought the frontman (the guy in the hat) was Tuomas Holopainen, so that video made me laugh more than it originally would have, had my brain been working correctly....I now want to see a Nightwish vid with Cossack dancing
