If you turn it off and do NOT even try to install anything, does it still
turn itself off after a while ? If so, it's probably heat related. Before
going too far into troubleshooting, and you check to check that no vents
are blocked, to see if a bad/slow fan internally, use a portable fan to
blow on it and try again - OK now ? Or still powers off ? Can you see the
fan turning just before it powers off ? ( some fans do not spin all the
time - may be only when needed )
If now OK with external fan, then it IS a circulation problem. Hook up the
hose on your portable vacuum cleaner and vacuum any vents, then hook up
the hose to BLOW out the air and go around the PC again. Power back up.

Sounds like this issue not a problem right now. Is this the same PC ? You
did not mention : XP ? Win98 ? The network card IS enabled ? what status
does "PROPERTIES" show ? Any firewall / software installed ?
start-run- 'cmd' (or "command"), then type "ping 127.0.0.1": it should
echo back to you 4 times = internal network OK.
