Case fans/lights turn on for second, but whole computer won't turn on.

Some lights flash for a second but computer won't turn on. I know that the case lights and fans turn on but the cpu cooler doesn't nor does the gpu in that second. i just moved from my dorm and set it up back home and this is when it wouldn't turn on. it seemed to be in a secure place during travel, so i'm not sure what to think.

Okay. Assuming you don't have an oversized air cooler, it's probably a short.

Remove/disconnect all components except the motherboard, CPU, and RAM. See if it boots that way.

despite me building this I'm still not confident in my ability to perform this. Not really sure what to unplug/disconnect, mainly what cords to take out.

Unplug the power cables to the Hard Drive and GPU. Next, remove the GPU entirely. Finally, unplug the SATA cable from the hard drive.

When that's done, attempt to turn it on and report the results.

Nothing happened, lights flicked as I hit the on switch on the back off computer.

What CPU cooler do you have?

Also, did you hit the power button?

What CPU cooler do you have?

Not sure but I'll look it up. I doubt its oversized due me using it for the last 4 years? I could be wrong though.

If it uses a 120mm fan or greater, it's oversized. Most coolers are these days.

152 mm, would that cause it?

unplugged the fan and still the same

The CPU cooler can act as a lever when you are transporting the computer. If you're in a car, and hit a bump, the CPU cooler can have enough momentum to break either the traces of the motherboard or the solder points of some ICs.

Normally, you would remove the CPU cooler before transporting the computer in a vehicle.

That cooler is a bit small for that sort of thing to happen. Did you hit any (large) bumps while travelling? Or (god forbid) put that in checked baggage on a plane?

Nope, just an hour and a half drive with no bumps I can remember,

If the machine was on it's side, was it secured from sliding left/right and forward/back?

If it was upright, was it on a hard surface?

upright, and seemed to be in a solid area. Not a lot of moving could've been done,

It only takes about 1 inch of drop on a hard surface, and less if it happens more than once.

If you have access to another machine, check to see if the PSU is good by putting it in the other computer.

I do not have access to another machine sadly
