Intermittant Bootup Failure: AT&T too much!

With increasing frequency, my unixpc shows an intermittant problem in which
it wont boot. The screen goes solid green (or bright green with a fine
black grid that makes it look like an array of small boxes, but not like
the line of small boxes at bootup). Usually this is upon powering up the
box, but once it crashed with no messages and showed this symptom. In the
past Ive tried the solutions to the "drive doesnt spin-up" problem, shaking
the box and cycling the power. Eventually it is revived. Other symptoms
are that the keycaps lock LED comes on briefly and the fan works.
Since this problem has been occuring with increasing frequency, I sent it
in to AT&T for repair.
Unfortunately, they want to replace the motherboard and some other board,
at a cost of $1400! That's what I spent for it new!
So, Im going to have to try fixing it myself.
Can you give me a hint on what part of the hardware may be at fault? Is
the green-screen consistant with the "drive doesnt spin-up" problem?
Sure seems to me that this could be as simple as a loose cable or bad
solder connection...
Thanks for your help,
Leonard
