It could be. General weridness or unexpected shutdowns are also common signs
of inferior or dying PSUs.
You might also check if the switch itself is failing. With a modern system
(one using an ATX power supply), the power switch runs to two pins on the
mainboard. If you remove the power switch cable and short those pins with a bit of
metal (ie a coin), it should power on. The switch is a cheap fix, just cut
the old one off and solder a momentary (normally open) pushbutton to the ends
of the wires, costs like 45 cents.
However, if not there, I'd suspect the power supply. The cable usually
doesn't get loose because it has a little "hook" that snaps down once you push it
in, but worth a shot.
Monster caveat: Some "brand name systems" (such as some Dells) have power
supplies which are NOT ATX standard; a regular ATX power supply will result in
nastiness when you attach it. Others have odd shaped ones, so they might be
wired the same, but you won't be able to bolt a new standard one in.
Good PSUs:
Antec, Enermax, Sparkle/Fortron/FSP Group (same company), PC Power and
Cooling.
You will pay good money for a quality PSU, but don't skimp. A decent-make
300 or 350 watt will cost you between 30 and 50 dollars, but OTOH, it will
probably last you longer than one of those $9.99 "400 watt" models.
For quietness, get a PSU with a 120mm fan on the bottom, rather than an 80mm
one on the back.
Quality power supplies are sometimes a bit pricey in local shops; I'd point
you at Newegg, cos they have like 600 Sparkle models, and I've been extremely
happy with my Sparkle FSP300 series (it's lasted me from when I got a "pretty
high end" Athlon 1200 to the present, it's very good with a famously finicky
mainboard)
