Computer won't turn on at all, tried different PSU still nothing

[ziffland]

So a little background I have built a dozen or more computers and have never had any major issues like this one. So this computer was working just fine two days ago, i was gaming on it and never had any issues. I recently decided to recase it and the case came in yesterday, so last night I took on the project and everything went smooth and I didn't suspect any issues. However when I plugged it in and pressed the powerbutton, there was absolutely no reaction. So I made sure I had the powerswitch cable correctly placed and made sure all the cables from the PSU to the motherboard were tight, tried again and still nothing. So I tried another PSU still nothing. I manually reset the cmos nothing again. Took out my GPU same, tried that with only one stick of ram same thing again. Is it my mobo or could it still be the cpu? I think I know the answer but I really don't want that to be it

My guess is it's either a faulty power switch on the new case, or something as simple as not holding it down long enough when you turn it on.

The latter happened to me once when building a PC for a friend with a cheap case he bought. It was a bit embarrassing when I took the sys into the shop where we bought the parts and they turned it right on.

In my defense though, that was early on in my PC building days.

So I tried the above and it didn’t work, I also hooked up the old casesfront end cables just to be sure and still nothing, it’s gotta be the mobo right? There are no lights or anything on it

Could be MB, or even PSU. Everything OK with you wall outlet? Have you tried plugging it into another one?
