Sounds like hardware to me.
Does this happen when starting from a cold/ambient temperature, or is the
computer warm/hot from use?
If the computer does not start good from a cold/ambient temperature, but
then starts after a subsequent reboot, it is likely a cold connection
problem somewhere in the hardware. As the computer heats up the internals
expand, ever so slightly, and a connection that here to fore was missing is
now connecting.
This was very common in the 50's and 60's when tube type TV's were the
standard. I would go to a customers home and spend 1-2 hours touching
various suspect solder joints with the soldering iron. Eventually the
problem connection was found and all was OK - till the next one manifested
itself.
If performed a CLEAN format/install, and the problem remains - it points to
hardware.
If you performed an upgrade install from within Windows a software problem
likely just carried over.
