Hi everyone - my aim is to boot into the BIOS to install Windows 11 via USD but no display thus far. I've tried the following:

1. Removed MB battery, held power button for 20 seconds, re-inserted battery 5 minutes later
2. Removed a stick of RAM, so from A2 & B2 to B2 only
3. Cleaned RAM stick by blowing and re-inserted it in B2 (it's new anyways but still tried 'cleaning' it)
4. Tried hooking up my monitor via VGA then HDMI (one cable in tower & monitor only at a time)
5. Tried hooking up my second monitor via HDMI
6. Tried pressing F2 & Del in an alternating pattern while trying 1-5 above

No display yet; I do have a USB headphone that lights up a few seconds after boot tho which I think is supposed to happen. All fans in the tower are coming on.

My parts:
PSU - Thermaltake Smart 500W 80 White Certified PSU
MB - ASUS Prime B450M-A II AMD AM4 (Ryzen 5000)
CPU - AMD Ryzen™ 5 5500 6-Core, 12-Thread Unlocked Desktop Processor 
CPU Cooler - Cooler Master Hyper 212 Spectrum V3 CPU Air Cooler
RAM - Corsair VENGEANCE LPX DDR4 16GB (2x8GB) 3200MHz
GPU - None - using onboard (work station)
Storage - My old SSD and a new SSD for OS (both Kingston A400) - and an old Western Digital HD from 2008 (lol)
Fans - 2 x Kingwin 140mm Silent Fan, 2 x Kingwin 120mm Silent Fan
Case - Cooler Master MasterBox Q300L Micro-ATX Tower
Monitor - BenQ GW2480

Pictures of build: Google drive folder \*I unplugged my monitors for the pic of the back so you all can see the available ports so that's not the issue
