Who Me Too'd this topic

Hello Guys!

first time posting so I apologies if this topic is actually answered in this English part of the community 🙂

So I very recently bought this Erazer so I could stop getting my ass kicked in PUBG all the time as my previous rig is over 7 years old (Geforce 970) 😄 

However I am getting random reboots when playing games like PUBG and similar , strangely enough I am not when running stress test etc using 3Dmark or normal web browsing etc. 

So I started googling and found this thread on the German part: https://community.medion.com/t5/ERAZER-Gaming/High-End-Gaming-PC-Hunter-X20-MD34445-dauernd-restarts...

It looks like exactly same issue and the solution looks promising (thanks google translate!)  However the solution involves downloading a more recent BIOS version from MSI (MPG z490 gaming edge wifi motherboard). But when i download (2 file) it to my prepared USB stick (bootable) the M-FLASH does not see the files, it sees the folder and everything but do not recognize it as bios firmware. 

As Medion is using a more tailored version of MSI how would i go about to upload the stock one?   (version 7C79v18)

Any help is highly appreciated as this rig didn't come cheap 😞

Best regard
