Bootup glitch in hardware

[Smag]

Not had it once Reishen, boots up fine every time and bugs are very minimal (although I do have a strange pops and clicks thing on another post).

I've just updated to the latest operating system and i cant get the thing on at'all now. All the comes up is the led with a black screen. This is really frustrating coz I have projects that need finishing which involve the ti so I can earn what little money i do from making music. I did'nt really have any probs before I updated, I got the odd hangup, but i'd just take the plug out then put it back in then it would be ok.

help!!!
