AB350M Pro4 Blackscreens with new System

[URL=][/URL]Huhu, and that would need your advice, got a new system and that is quite unstable.

So my system has been upgraded from AM3 to AM4.

System:

Motherboard: ASROCK AB350M Pro 4 (New)
Processor: Ryzen 3 1300+ (New)
Ram: 16GB Crucial Ballistix Sport LT Gray DDR4-2400 DIMM CL16 Dual Kit (New)
Graphics card: Asus OC r9 290x 4GB Ram (taken from the previous system)
Power supply: Thermaltake Frankfurt 830W (from the previous system) and a new Pure Power 10 with 630 W (new)
SSD: EVO 500GB (new)
Operating system: Windows 10 Pro

It runs for 1-2 hours usually everything fine until I suddenly get a black screen, PC is still on, sound is still for 1-2 min. again given, fans still turn, only on the screen no signal appears.

System then reboots after a while, these more or less crashes are totally random from time, sometimes 2 hours or sometimes 3 minutes.

Only thought the PSU is broken, which is why I had exchanged them directly against the Pure Power 10, had unfortunately changed nothing in the situation.

Thought then graphics card but runs perfectly in other system.

I could already exclude:

- Graphics card is Okay tested in another calculator with benchmarks.
- Power supply I had directly brought me directly in the store NEN new.
- Mount / Spacers are all properly attached.
- Bios updates and graphics cards bios are up to date.
- SSD also runs perfectly in other system.
- Latest driver
- Temperatures are completely okay.

So it can only be the motherboard?

Iam got no clue, and no Idea , what is wrong, i build so many Systems and got no Problems with them.

Is it maybe something very simple like a bios setting that I have to deviate from the standard so it runs or hates this Motherboard r9 Cards ? or is it really a Hardware Problem ?

The happened several times a day is quite annoying when you mittem in chatting, playing, surfing is the one time you have no picture and PC restarts after 2 minutes.

Would be great if someone could help me.

Yes, bought a new SSD and installed fresh Windows 10 on it.

have you installed windows update kb4056892

its the initial update for the spectre/meltdown panic

this on my system started causing randon crashes

uninstalled it and lo and behold pc perfectly stable again (and they say it only affected intel cpus.....)
