Running Linuxmint and out of the blue pc wouldnt boot at all or post. There is no sound of the fans and nothing happens on the screen. I have tried reseating the RAM and it made no difference.
The only indications that power is getting through are a blinking yellow light at the front buttonfor switching off and a solid yellow light inside
I have tried the Linux forum and they reckon its a hardware issue
Please help

I suspected that the computer was a Dell after reading the following in your OP;

A failed PSU and/or motherboard are both strong contenders and as you cannot hear any fans running I would suspect and therefore check the PSU first, are you comfortable with working inside a computer.

Gday.
Thanks for the reply.
While Phillpower2 is offline I will row the boat for a while.
The PSU is at the top/back. I think it is a 306 Watt, would be useful if you can write down , brand/model.
If you have any other means of accessing the Web, please download the owners and service manuals.

Before working inside the computer, every time, switch off the PSU and monitor, take anti static measure by briefly touching a bare metal part of the computer case.
The lights showing both indicate,
I F THE POWER LIGHT I S BLINKING AMBER — The computer is receiving electrical power, but an internal power problem might exist. • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable). • Ensure that the processor power cable is securely connected to the system board, disconnect ev ery powr plug on the MB then reconnect.
Reseat the following, RAM, and if applicable, the video and sound card/s.\\If the issue persists, most likely the PSU failed, or, A SOLID AMBER LED ON THE MB, indicateda hardware fault.
Have you access to a PSU that can be used to test the rig?

Excuse the title of the tutorial How to Replace Your Desktop PC’s Power Supply In addition to the information at the link, get yourself some sticky tape that can be written on, use this to identify where each connection from the PSU goes.
Rig = The computer/hardware.

You are most welcome 
Let us know when the PSU has been removed and I will provide the instructions for how you can do a basic test to see if your PSU will power up at all.

when Phillpower2 gives you instructions for testing the PSU, it needs to be outside of the case, not touching internal parts, or it may cause a short.
From the info on the PSU, please give the brand and model number.
On this link, see last couple of pagers, Power Supply DC Connector Pin Assignments > http://downloads.del...anual_en-us.pdf

I gave model number as N 305P-00
So i need get into the PSU box yeah?
Member
To drop in, NO do not open the PSU box, just remove it completely from the computer is all, If possible take a picture of the label on the PSU, that model number may not be enough to find out what it is.
When removing the PSU, as suggested earlier, disconnect each connection, then with tape attached, mark where the connection goes back to when it is replaced again.
