ZoneAlarm reports all kinds of crap and you shouldn't worry about it. If it's there, it means you are protected. Anyway, ZA reported that those intrusions are blocked... why should you worry about it now ? I bet, you can find same or similar statistics on every single computer that is connected to internet 24/7.
Again, not being able to start your system is hardware problem, it has nothing to do with those intrusions ZA has reported. Especially, no one can change settings in your BIOS remotely, unles he's not in front of your computer. If you don't think so, well... good luck in searching, I tried to point you to the right direction. You said you need help (thread topic), so we are trying to help you.
Cheers !
