Sorry for bothering you. I solved the problem. The bios update fried the extra RAM cards I had installed. once I removed them it booted up just fine
Are you sure they are fried? I believe the bios update removes support for 1.5v memory. If you upgraded using 1.5V instead of 1.35V, this may be the problem. You could revert back to old BIOS, and continue using the upgraded memory if this it the case.
