Computer Won't Turn On

[Infested Cats]

My brother has had his computer for about 2-3 years now, and recently, he went to turn it on, and nothing happened. Literally, after pressing the "power button" on the case, there is nothing. No activity of any sort (fans, hds, nothing).

I checked all the connections, and everything seems to be in place. Other than that, I haven't attempted anything else. I figure it could either be the Motherboard or the Power Supply.

Any ideas?

sounds like power supply to me, i take it you have checked the fuse in the plug?

Or the power button is u/s won't be m/board cause the power would still kick it up just wouldn't go anywhere.
To check the switch follow the power on lead to the m/board take the cable off then slowly put a small screwdriver to the two pins and don't touch anything else.

You can test the power supply by shorting two pins but take a look at this diagnostic first.

Then maybe try this but double check your color codes first.

1st try plugging a lamp you know works into the same socket to make sure you got power then check the fuse in the lead is ok, try a different lead to be sure and as cwctv said check the switch itself

I don't see how I couldn't... It's plugged into a powerstrip.

Then go try the switch as said

these can and do go down seen a few in my time.

What did you do when you "tried another power supply"?

Have you tested the on/off switch?
