So yesterday my computer freezes up and I have to turn it off, then i go to push to power button back on to re boot as normal, but the green light on my tower comes on but nothing else, not to monitor, the keyboard, speakers, anything(everything is hooked up properly).........I'm having to resort to using a spare laptop as i type this which isnt so bad, but i have ALOT of vital documents on my computer that just shit the bed, has anybody else had this problem or even heard of something like this, its just like it went into a coma.......ANY input at all is greatly appreciated
