Weird Issue.

[40oz]

It has been 3 months since I built my new rig. Just recently it has been resetting quite a lot on its own and/or if I "tap" the case just a little. So, I thought of shutting down the computer and checking if any wires/hardware was loose. Everything looks fine so I ried to power it up again and it won't turn on...I have never faced a problem like this.

What did I do wrong?
Does anyone have any suggestion for fixing this problem?

Sounds like a grounding issue. Check to see if any part of the board or other components are touching the case or PSU.
