[SOLVED] Computer doesn't boot, no idea what the problem is

[abbybabby]

Hi everyone. I've had to replace the PSU, CPU and motherboard in my PC over the past two months. I'm completely stumped on what the issue could be now. I've made sure that each cable to secured to every connector, I've tried using each stick of RAM in every slot but still nothing. The PC seems to turn on for one second, instantly shuts down and doesn't turn back on unless I unplug and replug the PSU. None of the error code lights on the motherboard light up. Does anyone have any idea idea what the issue could be?

Please post a complete list of your PC's hardware components.

Sorry, completely slipped my mind.
Intel i5 9600k,
Asus Prime Z390-A motherboard,
EVGA Supernova 750 GT,
two sticks of adata XPG Spectrix D60G memory and one stick of Crucial Ballistix Tactical Tracer RGB memory,
Gigabyte GTX 1060 WF2 6gb.

Don't mix RAM in the first place.
Remove the GPU, reset motherboard BIOS, connect the monitor to the motherboard and try again. Yeah, with one stick of RAM in slot A2.

Still no boot and no signal.

Still no boot and no signal.

Remove the video card and drives, use 1 stick of memory, reset CMOS, plug the monitor into the motherboard and try to boot into BIOS

 

[abbybabby]

Still no signal and it still turns off immediately.

Tell what parts are connected at this point.

The motherboard, CPU and a single stick of memory. All my drives have been unplugged.

Something is tripping out the safety on the power supply.

You did only use the new power supply cables right?

Take the PC out of the case and try it.

No monitor connected?

On a piece of cardboard.
psu+mobo+cpu/hsf+1 stick of ram.

If it won't power up try a different stick of ram.

If it still won't power up your down to 3 parts.

===================

After thought.....replace the bios battery....it's cheap.

He has to unplug the PSU so it's tripping a safety.

Perhaps....just keep eliminating stuff making the suspect list smaller.

Thank you so much! This worked, I didn't really think the cables would cause a problem.

You were lucky most of the time it frys something.
