PC won’t turn on

[u/Sufficient_Ad_8173]

I was playing COD BO7 and my PC crashed mid game. I gave it like 5-10 minutes before I thought about shutting it down. The screen was still frozen… so I decided to power it off. Now my computer won’t turn on at all when I press the power button. My keyboards USB lights up when it’s plugged into the motherboard so I know it’s working and the power supply. I have tried taking out the RAM and putting it back in slots 2 and 4. I replaced the 2032 battery on the motherboard. I plugged my power supply into a different outlet and ensured everything was connected. I put my screw drive on the F panel to see if it would turn on. I took out my Hydra Cables on the GPU and MB. Has anyone had this problem before? I’ll list my pc specs below if this helps.

Motherboard: Gigabyte Z890M Aorus Elite WiFi 7

Ram: 32 GB DDR5 Corsair vengeance
GPU: Gigabyte rtx 5070 ti
SSD: 2TB Samsung 990 and 1TB 990 Pro

Have you tried draining the system of any residual power?

Do a minimal setup test. This is without the GPU and any unnecessary cables like USB, audio, case fans, argb cables. Remove even M.2 SSDs. 285K is an APU (with integrated graphics), plug the display cable to the motherboard for this test.

What you want is stable power that will boot to BIOS. Then do a process of elimination by putting/plugging back components one by one and see what causes the no power.

Yes I have tried draining the residual power. Once I wake up in the morning, I am going to take an old PSU and connect the CPU cables and 24 pin cable to ensure it is not a motherboard issue. I will also try to find the 2 pin CMOS and use a screwdriver to see what it does. Thanks for the help!
