Need some info here, did the issue start right after you installed the BIOS or did you run the BIOS update to fix the startup issue? Are you sure you used the right BIOS for your model? How far does the system boot?

You must have updated the BIOS, you can't "install a new version" of the BIOS unless you have a previous version of the BIOS or the system would not work at all.

The BIOS flash may have gone bad, can you boot the system again with the boot disk and try re-flashing, or does it not even allow you to try that? If you can't even do that, you may be in trouble as you can't fix a bad BIOS flash without replacing the BIOS chip on the motherboard in your system. Some higher end systems have a dual bios in-case this happens, but yours does not.
