"Your system may not be fully stable" post screen + weird voltage jumps

[neiru37]

Hey all, hoping to find some guidance on how to deal with a particular issue I've been facing.

 

Here's a video of what's happening:

Basically my computer doesn't always boot properly. Sometimes it boots fine, sometimes it only reaches the "Press F2 or Del" post screen but stays there indefinitely. And sometimes this happens.

 

Here's the hardware I'm using:

 

Ryzen 3950x

Asus B450 ITX

Timetec 32gb 3200mhz ram

Corsair SF600

GT710 GPU (just for testing)

Custom water cooling loop

 

How would I go about diagnosing where the issue is? Do I just send every component in for an RMA? Halp!

 

Thanks!

I see you are running an older BIOS (version 2901 in your video).

I would update to the newest BIOS (version 3004), and see if it fixes it.

 

Probably not the best idea to run a power hungry Ryzen 3950X on a B450 ITX motherboard as well...

Would've gone with a ASUS X570-I, ASUS Crosshair VIII Impact, AsRock X570 ITX/TB3, or Gigabyte X570 Arous ITX.

Those are 160A+ Core Current rated VRMs, with improved cooling.

 

ASUS StriX B450-I is 100A Core Current VRM motherboard, and not recommended for anything beyond 3800 / 3800X.

Since yesterday I'm having the EXACT samt problem. I have updated BIOS to the latest FW 3004 but it didnt solve anything. 

I have

ASUS B450-E Gaming ATX

Corsair Vengeance RGB PRO 16GB (2x8GB) / 3200MHz

Ryzen 5 3600

Water cooling (deepcool castle 240 EX) 

ASUS RTX 2070 Super

 

Everything worked great until I tried to start the computer yesterday...

 

After BIOS update I even pulled the cable and removed CMOS battery to resest the whole thing. Didnt help.

When you say "pulled the cable" ... are you referring to the power cable going from the wall to the back of the PSU?

 

Just to be sure, you need to disconnect the PSU from the wall, AND remove the CMOS battery.

 

If you update the BIOS, on first POST, it will ask you to check your BIOS settings...that is normal. However, the system asking you to check it EVERYTIME you turn on the computer is not.

 

When you update the BIOS, you basically wipe whatever was saved into the motherboard....like in 'Men in Black' with the mind wiping flash.
