PSU damaged or something worse?

Specs: Windows 7
Okay. Here's what recreated the problem I have now:

Yesterday, my pc got stuck. Not even task manager would open. I decided to turn it off from the PSU switch, which apparently was a bad decision. After I tried to turn it on again, it wouldn't turn on.

Question is: Do I just buy a new PSU? Or is there a chance that something else got damaged too? How high is the chance that I simply need a new PSU? (I don't have the luxury to test and trial to figure out which components where damaged. I just hope it's just the PSU, so what are the chances that I'm right, from what you read) What are the complications of using the PSU switch to turn off your computer? Why is there a PSU switch if it's gonna **** up your computer if you use it?

If you are getting no signs of life at all then there is a good chance that the fault is with the PSU. The only way to tell for sure would be to test it (under the correct load) with a multimeter. That presumes that you know what voltages to expect at each pin.

Of course the switch is not going to mess up your computer normally (although you may well corrupt your OS by just switching a computer off). But your computer was already messed up ("Yesterday, my pc got stuck"). Whatever caused that probably put it into a state where once switched off (however you did it) it would not start again.

There are several web sites that will detail full procedures for troubleshooting a dead computer (Google is your friend). Alternatively, take it to a good repair shop.

Describe everything or anything that happens when you try to start your computer.

Don't just guess & start randomly replacing parts, you need to troubleshoot.

Absolutely nothing happens when I try to start the computer. i click the button, only the click is heard, nothing happens, as if it's not even connected to any sort of electricity whatsoever.

Your monitor should at least light up and show a message of some sort.

No, nothing happens. My monitor has it's own power supply so it's lit even if it isn't connected to the computer, and it simply says "no signal detected", same message that it'd say if it wasn't connected to anything. As I decribed, absolutely nothing happens if I try to turn it on.

Well the monitor message does tell us something.

Stupid question but are you sure there is power to the computer and the power supply switch is ON, if there is one?

And yes, I did read your first post. The proper way to troubleshoot is to start at the beginning.

If you provide some specs we would be better able to advise you. Especially on the current power supply. Do you use an UNinterruptable power supply or a power strip/ surge protector?

I have no idea man. Just assume it's the most common power supply type. Every computer I've seen has the same. And yes of course there is power to the computer and the switch is on. There is one. You said you read my first post. :P

When things don't work you try different things. You may have inadvertently shut off the power.

You didn't respond about the uninterruptable power supply (backup battery, in case you don't know) or a power strip/ surge protector.

You could take the time to read the label, or if this is a brand name computer, post the full model number.

All power supplies are NOT the same. Even if the power supply is the problem, you need to know what capacity to get as a replacement. The brand will tell us the likely hood that the power supply is the problem. Some are much less reliable than others.

You have given us nothing to go on yet.
