PC made a pop/spark sound?

[codyccollett]

I built this PC brand new 4 months ago and tonight out of nowhere watching you tube it makes a pop/spark sound and shuts down. I turn my PC on and it happens again 2 times after the initial time. I check all capacitors on my motherboard nothing wrong. my gpu works fine. It won't turn on now so I disconnect all of the PSU cords and then reattach them and now it works perfectly and it has been running for 10 minutes now any recommendations on what happened or what may happen in the near future?

What PSU do you have?

It is a Corsair RM 650i

I recommend not turning on that PC. Look for shorts, excess standoffs.
The power supply is good.

It has been on for the last 15 minutes running fine after I re assembled everything there is no bursted capacitors that I can see and if there was it would've shut up within 30 seconds of startup? Maybe it was a short circuit somewhere?

Yes, sounds like it.
