When I power on, the LED on my motherboard lights up fans start spinning. No beeps, no graphical output, nothing. I've been the no POST checklist, tested everything and I think the issue might be that my ASUS H81M-E needs a BIOS update for use with an i5-4460. I have 3 questions - Firstly, do you think my diagnosis is correct, secondly, is there any way at all to flash the new bios without the cpu, and thirdly, is there a risk of damage to the cpu if the system doesn't recognise it's there?
