Quick background. I've been building computers for awhile and I just recently purchased a new LGA 1150 gaming mobo and an i7 4770k as upgrades. I installed them but my computer wouldn't boot. Fans would turn on but nothing connected to the mobo had power (keyboard, mouse) and the bios didn't load. Another weird thing was I could turn it on with the power switch but it wouldn't turn it off. I had to clear cmos to get it to turn off. I sent the mobo back to get another and i put back by old hardware and yet the same thing is happening! Fans are turning but nothing will boot! This mobo doesn't have a clear cmos so I I have to flip the switch on the psu to turn it off. (psu is a corsair 750 with no voltage switch that I can see) I would greatly appreciate any help!!

not necessarily the PSU itself, the cable or the connector might have been damaged when you removed them, these things happen.
try to test the PSU somehow...

I'm using the old mobo now. I literally used my computer the day I upgraded and now I'm using the exact same setup and it's not working.

My old build was a mobo which a can't remember the exact model with an AMD 555 BE as cpu. Those are the only two parts I switched out. I upgraded to a MSI Z87-G45 mobo and an i7 4770k. I had problems so i sent the mobo back and now I'm trying to run my old build exactly as it was before with my old mobo and my 555. Except I'm still having the same problems. Just to clarify my old hardware (the hardware I'm trying to run now) was working perfectly fine a week ago before I tried to upgrade.

I checked the cable and it still looks good. I don't have one right now but I go to a university that has a pretty large computer science department. I'm sure I could find one there, it probably would come with it's own electrical engineer. I just don't understand how it could work perfectly fine forever and without warning be dead. The PSU that is.

try to test the PSU somehow, check if the voltages are ok. it would be really helpful if you could borrow another PSU from a friend to test with it.
