I replaced my 250W power supply with a 400W and now my PC will not boot-up. Even if I put the old P/S back in it will not boot. Any chance I have not done anything irrecoverable?
Oh yeah, before anyone asks, there is no chance I plugged it into the motherboard incorrectly, it is ATX.

Make sure of the obvivous and that all the power cords are plugged in and power is being supplied to the power supply.
The system board may have a bad power switch.

OK I agree you can only plug the ATX connector in one way (CAUSE IT IS KEYED).
Now you have removed the new PS and the OLD PS won't boot either..
Put the NEW 400 back in...
Step ONE.. CHECK the POWER SELECTOR on the back of the supply... 220 volts vers 110 volts.. YOU need the 110...
Step two..
Check all the cards including the AGP video card.. This is the easy card to disloge from it's socket and will cause a direct short on the socket pins.. When you power on there is as sensing inthe power supply and when the current demand is greater that the regulator.. CROWBAR... It will not let the power supply come on....
Step THREE... quick check.. you don't have to have the power connected to the drives to check your system.. just the ATX connector.. also make sure if you have system connected to power strip that it is connected..
Have you disconnected a cable and by mistake reconnected it incorrectly.. ie, IDE cable reversed will hold down you system also.. Smile you are not the first one nore will you be the last....
