The update didnt cause this problem for you, Eddie. Its physically impossible for an OS update to cause your computer to fail to POST.
Those beeps are beep codes, and without knowing the make and model of your motherboard, they're not going to get you anywhere.
If you just bought it 5 days ago, then return it. Otherwise, take it to a shop where someone competent (no offense meant, but it doesn't seem like this is within your skillset or something that someone with the appropriate skillset can walk you through doing) can take a look at it, and fix it for you. No, its not dead forever.
The update caused your computer to reboot, which is when the issue presented itself. Had you rebooted the computer without updating first, you would've had the same problem. Its called a coincidence.
The reason I am replying to you is that some tech journalist that doesn't understand tech quoted you and is spreading hysteria and false information based on YOUR post.
As I said, its literally physically impossible for an OS update to cause HARDWARE issues with your computer, which is what failing to POST means.
I don't think that particularly helps you at all, aside from recommending you return it or take it to a shop, but at least you won't wrongly blame Microsoft for an issue you just happened to have at the same time as you applied the update.
