PC no display after updating BIOS

[kifelnasir]

Hi, I built my first PC a few weeks ago and it was working fine until earlier today when LiveUpdate notified me about a BIOS update. I followed all instructions but the PC rebooted and stopped displaying to my tv.

Im using a Ryzen 5 1600 CPU with 16GB (2x8GB) Corsair Vengeance LPX RAM and ASUS strix 1060 GPU. The motherboard is a ASUS B350M Gaming Pro.

The PC appears to be working as normal as in all the fans work, usb stick has power too but my mouse and keyboard dont work and tv just shows no input.

I've tried turning PC off and disconnected plug to reset CMOS by shorting the pins, pulled out the battery, reinstalled the graphics card, reinstalled RAM and also tried different ports on the graphics card but still not working.

The EZ debug LED for the CPU stays on but im not sure if that just started happening or if its always been like that.

After a BIOS update it is usual for some settings to be reset to default.
With the card in the machine 1) If you have onboard video use that to get into bios and check video bios settings ie...onboard/discrete....or gpu order etc

This is an urban myth but It HAS worked for me before.

Turn off PC......
Unplug PC......
count to 30.......
DO NOT PLUG BACK IN........
Press and HOLD POWER BUTTON for 20-30 seconds (discharges power in capacitors etc)
Plug back in and cross fingers when you boot up.

Thanks for the reply. Unfortunately my PC doesn't have onboard graphics and I tried the method above but it didn't work.
