It would be helpful to have any idea what some of the errors these various problems give as output, even if it is a panic shortly after an attempted boot. Knowing what the problem looks like in those situations where the hardware may not be fully known, would be a great help in making suggestions for possible fixes- and also might help with generalizing with errors that have similar solutions.

A truly odd situation with CQ62-410us compaq/hp laptop which fails due to some kind of apparent BIOS error- pressing escape in order to cause a boot device selection of DVD seems to solve the problem and allow boot to continue.
