No post, Fan Spin, no debug lights MSI b450m-pro vdh max

[crazyfrog]

Any Ideas?

I've been presented with a b450m-pro vdh max with a ryzen 1600 all unknown conditon but the combo wont post.

I've added known working ddr4, rx 480 and also tried a 9400m and ryzen 1200.

After powering I get a short white light on cpu debug led then all off and fan spin. Theres a short crack on the motherboard speaker.

As the motherboard indicates, you got a dead CPU, incompatible bios or problems with the motherboard or its socket.

Ryzen 1600 is old so even factory bios would be compatible with it, try removing cmos bios battery and then put it back, test cpu on another motherboard to see if it works.

CPU light indicates CPU not detected or fail. Did you check the pins in the socket? If any are bent the mobo is useless. It won’t recognize the CPU. Did you match the little triangle on the cpu with the triangle/dot on the cpu socket?

[Chapunna]

What cooler is that? It looks like a case cooler not cpu, maybe motherboard does not detect that as cpu cooler and shuts down automatically for prevent damage. Try a better cpu cooler

sounds more like the bios was updated at some time with a bios that has removed both 1600 and 1200..

CPU is compatible even on the latest bios.

As in post I've tested known working ryzen 1200.

Agreed tried removing power, hdmi cable, cmos and shorting power headers for 30 secs and no change.

Havent pried off cover to inspect but looks okay, tried a known working ryzen 1200. No change.

Its just a big heatsink resting on the cpu and random fan, for boot testing its fine.

I'm sure latest bios doesnt  remove 1000 series support.

Try all ram slots, start from 1 to 4

I've tried them. Just gone onto spraying IPA into the ram slots and inserting and removing a ram stick, heating dry with a hair dryer.
Also done a really good visual inspection and no issues.
 
The crack sound on boot has to be a symptom of a hardware failure, tempted to try reading bios but I dont have the correct adaptors for my CH341a. I'm tempted to remove the chip and resolder to a small adaptor board but the PCIE slot is right next to it and too much bother.

Then you got a dead CPU.

tldr: "I tested a unknown motherboard with a bunch of known working parts and it won't even post"

opinion: bad psu or bad mobo, pretty simple.

advice: if your PSU is quality, replace the mobo first. If PSU is unknown junk, replace PSU first.

 

Edit: I see you are using an Integrator 500w, those are trash.

opinion: replace

advice: Don't buy less than gold psu.
