Bios Mods -The Best BIOS Update and Modification Source

Hi. Please, please, please!!!
I need get access to advanced options in BIOS!

Because when i bought laptop there was no OS but FreeDOS, and after installing Windows 10 Pro 64-bit from microsoft.com (ISO-image burnt into USB with Rufus), my computer lagging as [censored]!!! It stuttering awfully on most memory using programs like games, editors, etc. For example game PUBG, stuttering very BAD, i have GTX 1050, and on Very Low settings FPS is horrible, i mean it stutter... And also when i click WINDOWS key on below (taskbar), it reacts only in 2-5 seconds, and when i do it again it became normal... and if i wait for a while and press it again, it reacts with the same time or longer... sounds lagging, everything is very slow and S T U T T E R S very very bad... the laptop is a brand-new, no any physical damages no viruses no suspicious stuff nothing but stock device with stock OS...
i reformatted it so many times, tried everything like disabling Superfetch, Windows Search, MSISupported, tried install OS on SSD (ppl said it "HELPS"......), and so many attempts i can't remember anymore, i almost "broke" my pc with these tries... only i knew it got way worse...

Yeah and 100% the same problem was on my previous laptop it was acer aspire e1-772g, same S*** with the Linux DOS something first time. 100% same stuttering, same "Advanced" missing on bios :-( :-(
when i press wrong keys while on bios menu it BEEPS SO LOUD... for like 1 seconds... i heard you need to use "hot-key" in bios to "unlock advanced options", i tried Fn+F1, Ctrl+F1, Alt+F1, Shift+F1, Ctrl+1, Fn+1... *BEEP*...
I'm so done that i don't know what to do... what to do to stop this [censored] !!!!!!!!!!! it looks like a very very very simple solution... i feel it just... cuz laptop is new btw...
