I think the power supply on pc died

last while playing a game the computer turned and would not come back on, tried the cord no difference this just after a bought a new moniter for it a couple weeks ago.

I had something similar happen, turned out the power supply was ok. I ended up replacing the motherboard. (I did trial and error parts swapping with another system I had handy to pinpoint the problem)

Think of up grading the motherboard any way it is just great timing.
