BIOS fails during USB connection setup (new build/MSI B550)
BIOS fails during USB connection setup (new build/MSI B550)
Hey everyone, today i build my new pc and when I try to use any USB device in the BIOS it crashes. The problem The system loads into the BIOS as it should and all components are recognized (CPU/RAM/M.2) but as soon as i use my keyboard or mouse there is a short lag then the cursor moves and then the BIOS crashes. The screen turns black, shows no signal and the kb and mouse turn off, the fans of the computer stay on. After a few seconds the kb and mouse turn back on and the BIOS screen comes back, if I use my kb or mouse again it lags and crashes again. Sometimes I can navigate through the BIOS for a few seconds but it eventually crashes. (it crashes faster when I use the mouse and works a little longer using kb) It also crashes when I start up with a bootable Windows USB-stick in. When I don't do anything the BIOS stays on forever and doesn't crash (with multiple USB devices connected) but as soon as I use my kb or mouse it crashes. The system CPU: AMD Ryzen 5 5600G Motherboard: MSI B550M PRO-VDH WIFI BIOS: E7C95AMS.280 (06.22.2021) RAM: 16GB (2x 8GB) G.Skill Aegis DDR4-3200 CL16 M.2: SAMSUNG SSD 980 500 GB PSU: 500W Seasonic Case: Aerocool Trinity Mini-G-BK-v2 What I've tried different keyboards and mice (both wired and wireless, they all work fine on my other system) only connect one USB device at a time (kb OR mouse) every USB port different display connections (DP&HDMI) cleared CMOS disconnected front USB checked all cables fully disassembled and reassembled the system (checked CPU pins) Nothing worked. XHCI hand off and legacy USB support are enabled, I was able to check that just before it crashed. I don't have a keyboard or mouse with PS2 plug. The only thing that I can think of that is left is updating the BIOS. However I am hesitant to try that since it uses USB and if it's a USB issue it might crash and brick the system. I hope someone has experience with this issue and can help. Thanks in advance.
Verify the motherboard stand is correctly positioned to avoid unexpected issues. A BIOS update can be performed without any connected hardware, except power, and you won’t need a CPU installed. Refer to the manual for guidance. I’m considering trying it, though there’s a risk of damaging the system. The update will download from USB and check the file before proceeding, after which USB access will be disabled. Results aren’t guaranteed. I’ve encountered similar problems with certain motherboards and peripherals—never every USB device works.
All confrontations are positioned correctly—it’s quite strange.
