Motherboard wont turn on HELP NEEDED

[FalconWingz]

So i disassemble my old PC.

I re-plug everything

It wont turn on

 

So I unplug everything other than the 24pin to my motherboard, and 8 pin extra.

Still, no beep

 

However when I turn off the power, theres slight sound in the psu when it turned off

 

But when I turn on my PC through the case button, the motherboard wont turn on

 

HELP

Check if the cable got undone in shipping or something, make sure all the prongs are in

I did unscrew some , and havent screw some back though, but I dont think it affects why it wont turn on. Am I right ?

Did you plug the floppy drive connector into the motherboard?

Unplug that (beneath the 24-pin) and with luck it should be fine.

Does is power on without the 8-pin CPU power connected? If so, dead socket or CPU.

Good call. Yeah that's totally the issue. Applying power to a header trips protection. If it didn't the board would've fried, which it still might have.

Wait, are you trying to boot without RAM or did you remove it just to show the cable was plugged?

Yes, you'll need your RAM in the board to POST.

Yep, RAM is always required as the memory test is part of the POST. No memory or CPU is a POST failure. Some boards don't post without a functional graphics chip either.

Yes.... Yes you do need the RAM to access the BIOS. The motherboard doesn't have any RAM chip on it to let you access the BIOS without it.

I mean at the end of the cables, where the cable turns into an adapter, make sure the wire is fully in.
