Compaq presario sr2010NX won't turn on

[courtm70]

I have a compaq SR2010NX with windows XP and ethernet that runs through a netgear module through the wall plug-in. I downloaded norton updates the other day and can't remember if I shut down the computer or not. Anyway my son turned off the power cord. When I turned it back on, the computer would not power up. The light on the hard drive does not illuminate and the fan does not run. I have checked the wall socket and power cord and they are fine. I also checked the power cord at the back of the cpu and tried other sockets, to no avail. Any ideas?

It probably has a cheap psu on it that now needs replacement.
Why on earth did you put norton on it? It is seriously crap.
