Re: GA-73PVM-S2H - BIOS freezes after update.
My initial guess would had been that the cmos battery was dead before updating the Bios... but now that you are where you are, if you have another power supply or can borrow one I'd try that as... Flaking power supply can cause what you are seeing.
as for the MS software, as long as you have the installation CD/DVD's and the activation codes, the software is yours and you will be able to activate on any new system you get if need be.
