Can't get onto ASUS BIOS, help!

[AJ9090]

I'm having some trouble with getting into the BIOS. Since I first got my PC from PC Specialist it would show a screen with their logo for a few seconds which allowed me to enter the ASUS BIOS but since reinstalling Windows 10 last year this screen no longer shows and within a few seconds of turning on my PC takes me straight to Windows. What can I do about this? Is there any way to get ASUS's own BIOS back as I used it to control my fan speeds? I use the AISuite3 to control my fan speeds at the moment but I don't have a lot of control over which fans I want to change the speed of because the software doesn't detect them all properly, was much easier with ASUS BIOS.

I would really appreciate it if someone can help me with this.
