Thanks 
Everything lighting up does not prove that the PSU is 100% good but it does make a faulty PSU less likely.
If you can`t borrow a PSU it would be better to find a reputable tech close to you and ask them what they would charge for taking a look, it would hopefully be less than purchasing a test PSU.
Options that you have left are doing a barebones setup outside of the case and if still no change removing the CPU from the socket and powering up the board to see if the RAM LED behaviour changes and - or if you get any error beeps.
Let us know if you need a guide for the barebones setup.
You are welcome.
