Hello,
I have a new build with a Z490 Taichi and an i9-10850k. This morning I ran A-Tuning and hit the tuning process button and let it do it's thing. I walked away (yeah i know. bad idea) and came back to a mess. Computer powers on and all RGB lights up and the red error code led just shows "00" but i get no video signal. i tried the GPU and the CPU HDMI ports and get nothing. Can i assume that the MOBO is fine because of the red error leds? did this dumb software fry my cpu? please help me diagnose so i can get it back up. thank you

Dear Hawkhandler,
Thanks for posting.
Regarding your case, kindly try the suggestions below:
1. Install minimum bootable components to the system.
2. Reinstall the CPU and the power supply.
3. Install only one RAM to different RAM slots.
If the problem persists, please refer to the page. 31 in the following link and use flashback to flash the BIOS.
