I was googling it a little bit and found out that it means everything went well and startup was successful but i don't want that beep it's very annoying and I wake some of my family members up when i turn it on. I have Biostar TA790GXBE motherboard. I know it could probably be disabled somehow in BIOS and i was searching for it but couldn't find it. If you could give me a video or at least a few shots how can i disable it. That'd be great. Thanks!
