I mean try and use another switch like from your case possibly or one you have lying around.

I have the exact problem before. It was a problem with the cartridge of the ram slot which was not well connected to the motherboard. i accidentally tapped on the ram slot (very lightly) it would cause the system to restart automaticaly while it was turned on... but that was for me, im not sure if it could have happen to your mobo as well. Other than that, it could be the power switch what lemondrip said.

Its the Dimension 5100 and yes, it does turn amber.

check the motherboard for bulging/leaking capacitors on the motherboard. don't know about the 5100 but there have been a few series of dells that had that problem and the amber light usually means a mobo or PSU. if the psu isn't the problem like you have diagnosed it's the mobo

Can't you look at the "dummy lights" which work in a similar fashion as motherboard beeps on a Dell? They are 4 LED's in a row numbered 1-4. They will be in a certain order of on/off and yellow/green (can't remember exactly) But then you can look up the code online and narrow it down from there.

Dell uses differently wired motherboards/PSUs, you probably fried the board just by trying to turn it on with the RoseWill.

Seem's I was a little off. They're called "Diagnostic Lights".

Here's the link for all the different codes - scroll down a bit.

@RussianGrimmReaper

The cables went in fine. Also, I've done this testing method with other Dells and HPs.

@XshiftX
There is only 1 small LED
