Sounds like your laptop is probably FUBAR but maybe there's a way to fix it. The BIOS might be flashable through Windows, you should check the drivers page for your laptop and it should have BIOS updates on there with instructions. It might be flashable in other ways than specified in the instructions, there are multiple tools available to flash BIOS files, but which ones will work for your PC is hard to say.
You can't boot from DVDs so booting from USB devices is probably also not an option, so you can't flash the BIOS that way.
The last way to flash a BIOS is the one usually built into the BIOS itself, exactly how to access it depends on your BIOS, but usually it goes something like, download the BIOS update, put the .IMG file which has a special file name on a flash drive (FAT32 formatted I think?) and it will either be detected automatically on boot by the BIOS looking for that specific filename, or you have to hold a key combination to start the update process.
