Thank you Dwarf, I should have unmarked.
I appreciate you trying to help with the PSU, but it's not just that it will not boot. As I stated in my previous post, I believe it blew a capacitor due to the extremely loud pop.
Was asking if anyone had experience with blown PSU capacitors, and if it would take other components with them.
Just got a call from the shop, the only component that went was the PSU. Tossed another psu in and it fired right up.
Remarking as solved, thank you to all who took time to lend a hand!
