Unresponsive Build

[Copyright Inc.]

I am currently trying to troubleshoot a pc i've built. I have not encountered any severe issues in almost 3 years, but last week it happened. The incident was described as such: The user was afk for some time and the monitor went into sleep mode. When he returned to the pc and "woke" the monitor, it was only displaying on half the screen, where it was downloading something while showing static to some extent (Couldn't get clarification on what was downloading/installing). He then pushed the reset switch and later on held the power button down. Since then i have had no video output signal. The fans start spinning up, the leds on the gpu works. The debug LED for a cpu error does light up (which indicates an error), but only for 5 seconds (this happens on both mobos). Even when i have changed to different gpu i still have no signal, so I don't know what else could be wrong, but with two different gpu's on two different mobos and still no signal, i'm clueless as to what the issue is. At this point i have litterally no idea what could be the issue and i'm thinking about just building an entirely new system.

ANY help is appreciated

 

The specs:

Mobo: MSI B450 Tomahawk Max
CPU: AMD Ryzen 3600 + stock cooler
RAM: Corsair Vengeance LPX DDR4-3600 C18

GPU: ASUS ROG Strix 5700xt oc

PSU: CM V750 v2; formerly a corsair rm750x (which stopped working for no reason)
Storage: WD Blue 3D NAND SSD 500gb + Seagate BarraCuda 3.5" ST2000DM008 - 2TB

 

I have tried the following solutions:
Switching between hdmi and dp output
Changing PSU

Changing mobo to a MSI B450M Bazooka MAX wifi

Changed gpu to Nvidia GT710

Clearing CMOS

Wrong info on incident

Maybe a RAM stick died. Try it with only one stick, assuming you have 2. Maybe ask a friend if you can borrow a stick to test.
If that is not the problem, only thing that could be wrong then would be the CPU. Did you overclock it very high by any chance?

I have updated the post to the actual story on the incident, not just what i could remember. Aside from that, the CPU is running stock and i'm running XMP on the ram. Though i don't have an extra ddr4 kit on hand, but i'm gonna try with a single stick

The debug LED lights up on my system as well. This happens during boot and is followed by the debug led for ram and GPU in my system

I'm just writing what i see since the manual states that there's an issue with the component if the LED is lit. On this system it's only the cpu led that lights up shortly. After I have heard the actual incident, im starting to think it's the gpu, but that still doesn't explain why i can't get any video output with another gpu or even on another mobo

well.. since you have several mb's and gpu's. i hope you have another cpu to test? .. altho it passes it's not going further either?
