[SOLVED] will a motherboard post if cpu is present but no thermal paste or fan on top of it just connected on header?

my rig
ryzen 1200
rx 570
MSI a320
4 gb *2 ram

no it won't. it will heat up to extreme temperatures almost instantly and then shut off to save itself from certain doom.

You need to use thermal paste and properly attach the cooler WITH a fan connected to CPU fan header.

so may i assume that's a feature that stop the motherboard to post ,even the psu does not start?

...even the psu does not start?

THAT changes the tone of the question quite a bit....

If the PSU doesn't even attempt to start then the CPU never has a chance to overheat and shutdown before POST concludes...so I'd say something's at issue in the PSU's startup process. Take the CPU out of the board then try it: it should fail POST with diagnostic LED's lit or speaker beeping at you.

If it does turn on then CPU's probably faulty, but put a heatsink on it to be sure. If it is faulty then it didn't shut down in time and you might have toasted it...if it wasn't toasted already.

If it doesn't turn on with CPU removed then paperclip test the PSU with it completely disconnected from the motherboard, if it still won't turn on then it's faulty. If it does turn on then the motherboard's probably faulty.

i see i figured out the issue there was a chip on mobo beside the cmos that had corrosion everything worked fine after replacing it but as you said i already did the paperclip test it was working
