I have this motherboard for a while now and I had some issues with it. The last time I had to change the boot configuration because it wouldn't boot further than BIOS. Yesterday I powered my PC, BIOS/Mobo screen appeard for 2 seconds as always and then nothing happend. I restarted, nothing at all, no video signal, no power on the usb ports. The EZ debug LED stops at the VGA indicator. Since then I tried a lot of methods but nothing worked for me. I am also pretty sure that the problem is not my GPU because when I had a similar problem I exchanged my GPU to make sure it is not the cause. I think it might have to do with the boot configuration but I'm not sure since it doesn't even get to the boot LED.

Specs:
Ryzen 7 2700x
Rtx 3070ti fe
B350 gmaing plus
32gb Corsair Vengeance pro 3600mhz
700w pure power 11 CM

SanDisk SSD 120gb
WD Blue HDD 1tb
 
Codes are ment as debug light? Usually the CPU light turns on first for a second, then nothing and then the VGA light stays on. After clearing CMOS:
CPU light turns on first for a second, then nothing, then the CPU light turns on again for a second or two and then the VGA light stays on.

debug code if your board has such function

Usually the CPU light turns on first for a second, then nothing and then the VGA light stays on. After clearing CMOS:

If you press reset button and waits does it pass it?

i have exactly the same issue with my b350m mortar arctic. some months ago, i update my windows to 11 and poped up a msi updater. i ran trough the update process, at the end my pc restarted and got this ez-debug light stuck at vga led. later i bought a new rtx 3060 instead of original gtx 1050ti and a new psu for it, cause i read online the cause of the issue is a new bios update which makes video cards before 2019 incompatible with the board. but the issue is persist.

i tried everything i found in forums, such as boot with and without graphics card, with one and two stick of ram, try booting only with cpu, clear cmos, short jbat jumpers.

specs:
ryzen 5 1600x

I have exactly the same problem with my B450i Gaming Plus AC motherboard. I upgraded to Windows 11 back in november, had to flash my BIOS to the latest version to get it all to work. It seemed to work all fine, until my PC stopped working sometime around january. The VGA boot light on the motherboard is led, indicating it can't find a GPU (according to the manual). I put in a new videocard (Asus Radeon RX 550 EVO Phoenix 4G which did not require any aux-power) but this didn't make any difference. I tried to reset the CMOS and even replaced the CMOS battery, all to no avail. I don't think there's a problem with the power unit as all components seem to get power (fans turning, DVDRom can be opened/closed, all motherboard/case leds are working). Quite frankly am at my wits end here.

At this point I'm having serious doubts about the motherboard. What's striking is that around the time I upgraded to Win11 I had major stability isues which I could eventually lead back to a faulty RAM module, which I had subsequently removed. I can't help thinking that the latest BIOS upgrade (7A40vAH3(Beta version) which I needed for the TPM support required by Win11) has something to do with this all, but then again: It has worked fine for about 2 months....

I was running my PC with basic settings, nothing overclocked.

My setup:
MSI B450i Gaming Plus AC
AMD Ryzen 5 2600
G.Skill Aegis 1x8GB DDR4
MSI Geforce GTX1060 AERO ITX 6G OC
Crucial MX500 SSD 500GB
Corsair RM550x

I had the same issue during a Windows 10 update a few days ago. It would get stuck on the VGA debug light on boot no matter which GPU I tried in any of the PCIE slots.

SPECS
- R5-2600X
- MSI B350m Mortar Artic
- 16gb DDR4 ram
- Various GPUs (R5 340, RX 580, GTX 1650, GTX 1660 Super, RTX 2060)

Suspecting a BIOS issue caused by the update, my issue was FIXED by pulling out my R5-5600g with integrated GPU from another system, dropping into the mainboard and it booted into the BIOS screen where I was able to re-flash it with the latest BIOS - 7A37vAM6(Beta version) found here (https://www.msi.com/Motherboard/B350M-MORTAR-ARCTIC/support#bios). Tested and confirmed working with all the discrete GPUs I had, replaced the R5 2600X back into the mainboard and tested again with the GPUs again. All working, no red VGA debug light after the BIOS flash.

Long story short, if you are able to get your hands on an AM4 CPU with integrated graphics (R3-2200G, R5-2400G, R3-3200G, R5-3400G, R5-5600G) that is supported by your mainboard, you may be able to boot into the BIOS screen to re-flash the BIOS and fix your problem.
