That's a touch-screen monitor -- special software/drivers installed??

Nope just a regular lcd monitor. No special softwares. Only has an analog input too.
It sounds like it might have a dry joint. This means the soldering on the circuit board is no good and can ususlly be fixed by resoldering it. But they are hard to find if you don't know what your doing you would have to know how to use a multi meter to find the dry joint. This will be why it works once it is warmed up the solder expands in the dry joint causing it to contact properly. Very common problem with monitors.
I forgot to mention before that when it blinks, I can wiggle the power cord right next to the monitor and it would work properly again. Could it still be a dry joint?
