Hello. I own a gygabyte z270x-ultra gaming motherboard from 2017. I've attempted to access BIOS and enabled safeboot (which is set to Battlefield 6). The boot partition is GPT. After this, the PC won't start properly—no POST output appears on the screen. It powers on but restarts after a short time. Upon opening the case, I noticed the DRAM and CPU status lights are lit, suggesting issues with those components according to the manual. My previous steps: changed CMOS battery, reset CMOS by shorting pins, swapped RAM and tested one at a time. At this point, I believe it's best to take it to a repair shop for a BIOS reflash (hoping other parts aren't permanently damaged). Before doing that, do you have any suggestions on what else I could try? Thank you.

Hello Asus isn't Gigabyte. It might seem odd since you usually don't tamper with BIOS when using safe boot. Consider shutting off the power supply and taking out the drives if they're connected via SATA. After that, remove the CMOS battery for five minutes. Then attempt to boot again. You should notice the splash screen.

Sure, I'll give it a shot. Just to be sure, does the system boot normally when the SSD isn't powered on? It seems like it should work through the BIOS.

Remove all storage devices. It will still start up via BIOS. This is just to see if the drives are functioning. Occasionally when drives fail, the system stops booting completely.

Thank you for the details. I tried to follow your guidance, but unfortunately the outcome remains unchanged. The computer starts up and shuts off instantly. It goes through a reset cycle where it powers on, attempts to boot for 10-15 seconds without displaying anything, then turns off again. After that, it restarts and tries to boot once more.

Ensure CMOS is cleared. If your CPU includes an integrated graphics unit, test without using a dedicated GPU.

An other option is purchasing used. I recently checked out a Z370 motherboard... Edited October 13, 2025 by leclod

Absolutely, if the repair shop tells you it can't be fixed, I'll keep searching elsewhere.

It appears the 300 boards don't work with 100 and 200 CPUs.
