Error code A2 - Cannot reset BIOS

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I unfortunately have only those 2 RAM sticks and I tried every combination.
And I have only that PSU.

I tested the min config without RAM, the computer starts, but displays nothing: is it normal?
The monitor works and the HDMI cable also works because I tested on other monitor/TV.

...
I can try to reinstall the power supply and the CPU: I'll test it tomorrow.
Thanks

	Dear Dani958, Thanks for posting your query! Since you have already tried to clear CMOS and minimum bootable system and the system is still not booting up. Kindly try the suggestions below: 1. Try installing other RAM on different slots. 2. Reinstall the power supply and the CPU. 3. If possible, kindly try with a different power supply. With thanks, ASRock TSD Edited by ASRock_TSD - 07 Jan 2021 at 2:10pm

	Hello there, I am Dani and I am new on this forum. And I have a BIG problem. My PC won't boot and show up the A2 code. I tried to clear CMOS, removed CMOS battery, pull out all SATAs. I tested on minimum configuration (CPU, 1 stick of RAM at a time) and USB keyboad: got the same A2 code. Help me please! I am desperate
