It is a likely cause, but not the only cause.

Any problems with memory tend to be pretty definitive on startup. Normally the
system will fail to load and will issue three beeps before shutting down or
exiting startup on a grey screen. But problems with hardware incompatibilities
(if there are third party add-ons), logic board problems (various depending on
hardware specs), bad sectors on the hard disk hard disk, I/O problems with
hard disk, fluctuating power supply from source, internal power supply due to
fail, over heating issues, running too cold, ... are all possible and likely
scenarios given the evidence to date.
