Windows 7: PC turns off while booting

PC turns off while booting

I recently changed my PC's power supply, but when I arrived home and turned it on, it turned off by itself a few minutes after booting the OS.
Now every time I turn it on, after a few minutes it powers down again while booting.
Any help? What more information should I give?

It would seem to be pretty obvious.
You change a piece of hardware and the computer starts misbehaving.
I would start with looking at that new psu.
It could have weak amperage.

What does weak amperage mean?
I'm going back where I bought the new power supply, to see if they know what's up. I changed it because the computer wouldn't turn on at all, so this is very odd.

Edit: Thanks for the response, apparently the power supply wasn't enought to stand the amperage from all the computer's parts. It'll get replaced tomorrow, let's see if it works out
