" rel="nofollow - Hi there,

Just changed my video card to Asus GTX1080 from RX580 and now my monitor does not show POS screen to enter the bios but boots into windows without any problems.

With HDMI there is no problem.

I've disabled CSM to solve the issue as done on some sources but system stopped booting and turned into BIOS screen.

My board is AB350 Pro4 with 3.3 bios.

Is there any solution?

" rel="nofollow - cronus75tr, no answer, just want to know what the POS screen is. Enjoy, John.

EDIT: What button(s) are you using to open BIOS? Have you tried the ASRock "Restart to UEFI" utility?

" rel="nofollow - Lol, I was wondering the same. He (she?) looks like a non-hater (in contrast to me), so I just assumed.

But yeah, better to clarify.

Intention is there. We were just curious what EXACTLY did you mean.

Another guy here just solved a similar issue with his AB350M by performing some 'CMOS rest boot'. Please search for the topic and try the same thing.
