Question PC won't boot to bios

[ahemuro]

was streaming a tv show with plex to my ipad last night, heard my pc just turn off, figured it was a power flicker and went to bed.

this morning my pc won't boot at all. i get a green light on the mobo, but hitting power ill get a flicker of light on the cpu and thats it. no fans kick on or anything. tried removing the cmos battery, taking out and moving the ram, checked all cable plugs. i installed a new gpu about 2 months ago but that was the last time i opened the case.

any suggestions on what to do next? is it likely the power supply?

welcome to the foums
easiest way to test the PSU is to swap it out. can you access another one for testing?
you cannot really test anything until the power is known good and working.

unfortunately i can't swap for another right now, unless i purchase a new one from newegg or amazon.

i bought a new power supply and installed the new one, but its having the exact same issue. any suggestions on what i can try next? seems like power isn't getting to the motherboard maybe? could the mb be fried?

you should try testing it with a known good power supply. yes, it is likely the power supply or the motherboard.

good power supply. next on the list is the motherboard, CPU, or RAM. all are needed for POST.
