USB not recognized in uefi bios

Hi, What motherboard?

asus
p8z77-v

The board has 2 black USB 2.0 ports. Have you tried them? What are the stability issues?

My GPU keeps hanging and gives me sound loop crash and I have read that updating BIOS helps with it and I also know that the tech supiport for my GPU will tell me to do that to....
And The only usb slots I see on my mother board are the two front panel usb 3.0 more usb 3.0 in the back, a slot designated for bios flash back and the mouse keyboard slots,

Top to bottom, second row.
Check the manual if not sure which are 2.0.

Ok thanks gonna try it later if it doesnt work might try other USB should I be formatting it to fat? Or fat32?

FAT 32 should work. Try also different drivers for the graphics card.

I already did
I tried old drivers the current ones and beta drivers I read somewhere that some of the cards have glitches with PCI 3.0 so If the bios update doesn't fix that I am probably just gonna RMA it and hope the next one works

dark the z77 mb from asus you need to rename the flash file. asus has a free tool to do that or you can rename the file per the renaming list under guilds for your mb. if your trying to use the usb flashback port it the blue port bottom one under the ethernet port. (have the mb off snd on standby power). when you press the flashback button if the bios file is named right the port will start blinking and you see your usb stick turn on. if your using the mb bios flash tool inside the bios. the bios will give the usb stick a name like fs0/fs1/ you have to slowly read the drives it fines to see which one is the usb stick. on my asus i just drop the file in the download folder on drive c: and find it using the search feature in the bios.

What do I have to rename it to? And how do I do it

Umm anyone know how to rename it?

Z77VB.CAP
But I would try to flash from BIOS and not by Flashback.

No thats what Im doing but the bios flash utility just doesn't recognize my USB I have tryed every usb port and it is formatted to fat32 what am I doing wrong?

Do all the USB ports work in Windows? Have you tried them all? It might be a motherboard issue and instead of flashing the BIOS, you might better RMA it.

No the usb appears in all slots on windows just doesn't appear in the bios

No other ideas. You can try using the Flashback (see the manual for how to). I would RMA it.

RMA what the board? And are there any more options on how to flashback or do I have to use the usb

Yes the board. For flashback there's a dedicated USB port.

Ik but I dont see the button Im supposed to press

It's at the bottom of the motherboard. Check firstly the manual here: http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z7..., under Manuals.

Ok so how do I use that then?

And Im pretty sure it wont work as the USB is just not detected in bios could it be the USB itself?

dark it easer to unzip the bios flash file to the hard drive then use the bios program in the bios to find it. that how i do my sabertooth bios. i put it in the download folder then search using the bios program. you go under windows/users/download and the flash file will pop up.
