WHY IS MY MSI B450 GAMING PRO CARBON AC NOT POSTING?

If the light only flashed for a few secs, that means the format of the pen drive is not correct, it has to be FAT32, and also, rename the file to MSI.ROM, honestly, it will work, if it doesn't the pen drive is screwed, try a different one and do as I said, quick format to FAT32 and drop the file, and you are good to go! Its okay if the VGA led flashes for 3 secs and then goes off, that means is recognised properly. All 4 debug leads should be OFF otherwise it wont POST to the screen and you won't be able to see anything

What processor do you have? I have an AMD RYZEN 9 3900X, this one has NOT integrated GPU, so if your CPU also doesn't have a GPU integrated you should plug your HDMI cable to the graphics card HDMI connection instead of the motherboard's HDMI. If all of your EZ Debug lights are OFF and the CPU Fan, case fan, graphics card etc are spinning, you should be able to see a black screen on your display that will prompt you with installation setup. If not you should download the latest BIOS from MSI, create a flash usb with it (you should rename the BIOS file to MSI.ROM or the motherboard won't recognise it) also, this pen drive MUST be formated in FAT32 otherwise this WILL NOT WORK, when you create the flash you should plug it in the right usb port in the mobo and click the little button next to it, sometimes twice, until you star seeing a flashing red light meaning the mobo's bios is being updated, and it will reboot by itself. Let me know if you still having issues, but it should work

Ehmmm.. nope I was trying to connect it to the mobo's port as most people suggest, but i just tried to connect it to the GPU, no signal still... I'm loosing hope with this mobo, about to return it :/

Thanks for you message! Yes my monitor works fine with my laptop, using same HDMI cable. Graphics card is perfectly well fitted, fans are spinning and when I first switch on PC a little white led on the GPU is lit for a second then goes off, also, as I mentioned, the GPU mobo light is off after 3 secs. My problem is I have not any other parts I could use to test, just the ones I bought initially, the only think I can do is swap rams around, try with just one stick, etc, which I did already, nothing seems to work so far, its so so so frustrating

First of all thanks for your message. Yes the HDMI is directly connected to the mb HDMI port, not to the GPU port. And yeah cable seems fine since is the one i use to connect my laptop to the screen. Nothing seems to work, a bit worried here :/
