[Danovic]

Hello,
today i put together my Gaming PC. When i try to turn it on, it works for about 5sec then turns off. After turning off, it automaticly starts for second time and then it works fine.

Does anyone know a solution for this problem?

The parts are:
MSI MEG Z490 Ace
32GB G.Skill Triden Z Neo DDR4 CL16
Seagate IronWolf 4TB
SAMSUNG 970 Evo Plus 500GB
NZXT Kraken X73

Best Regards

Is it new?
At this point....I'd be suspecting the power supply and I'd also check that the outlet is grounded.
I've seen what you are describing happen with both of those things.

The PSU is new and the outlet is grounded. On MBO there is a led display with numbers, it shows me "98" dont know if that means anything

From the manual.....

98 is "console input devices connect".

....and this is what I found from another post....

The error basically points to an input device such as a keyboard, or mouse.
or any device connected to the board failing to be initialized.

Other key components for the board to give a message like this can be because the graphics card if in a Pci-e slot is not seated right.
Or due to weight and stress of the card no longer being level or in line with the slot it`s self.
Making and breaking on the internal Pci-e slot contacts.

So....I would power down and check/reconnect everything.
If that didn't work.....I would try and start the machine....eliminating devices one by one.
