I upgraded the BIOS to the latest version in SETUP and after that it doesn't POST and all I get is a black screen. Iv'e tried many troubleshooting scenarios, no luck.
When I remove the RAM, I can hear the RAM Error beeps.
Clear cmos, connect to the internal video port, and see if you can enter the bios. Bios updates reset the bios so it may be using the internal display instead of your add in card - if you have one.
Thanks for your response. I have already cleared it using the jumper on the board as well as taking out the battery for few minutes. No luck. I've tried both external gpu and internal graphics.
