Asus P8B75-M LE - can't get past bios

Hi. I recently bought an Asus P8B75-M LE along with an MSI GTX 660 Ti OC, Corsair 8gb Vengeance ram and an Intel i5 3570k. My ancient nForce (don't know which model) was falling apart, and it had an AMD cpu socket (AM3 i think) which obviously didn't support my new i5.
The installation of the new motherboard went smoothly, and wired properly (I should also note that it was the first time i ever changed a mobo). When everything was set up correctly, i started the computer and i got this "error" that told me to enable CSM due to "compatibility issues" or something (I don't have access to the computer at the moment, and my memory is a little rusty). When i pressed "OK" i got directed to the BIOS setup/settings, so i enabled CSM, saved the settings and rebooted. I still got the same error upon startup, even though i enabled it. I retried a couple of times, i enabled Legacy OpRom instead of UEFI, and fiddled around with the settings but to no avail. I searched google, the forums on this site, and several others, but i didn't find anything. I tried disabling CSM, and surprisingly i didn't get the error. However, this time i got another error which said: "Video card does not support UEFI" or something. I had two options: F1 to continue or F2 to enter setup. When i press F1, the system restarts and once again i'm back at the setup. I have no idea what to do. Help!

I'm sorry for the long post.

  1. Hi, Although not recommended, in your case I would try updating the BIOS.

    I received a driver disc with the motherboard, but i'm unable to insert it since the disc drive will not open. Will i have to copy the contents into a flash drive from a different pc? I tried getting drivers from the Asus website, but i really have no clue which one to download. (I'm really new to this stuff)

    Thank you for the reply
  3. http://support.asus.com/download.aspx?SLanguage=en&p=1&s=39&m=P8B75-M+LE&os=&hashedid=hAE3jGXTUebROVRb
    under BIOS.
    Download, unzip the 1101 BIOS file and save it on a FAT formatted USB stick. Insert the stick in a back USB 2.0 port (black).
    Enter BIOS and use the EZ Flash tool for updating it. Make sure the power does not go off during the process.
    By the way, what's the board BIOS version?

    I'll try that as soon as i can, thanks!
    Hm, i'm not sure. The specs say: 128 Mb Flash ROM, AMI BIOS, PnP, DMI2.0, WfM2.0, SM BIOS 2.5, ACPI 2.0a, Multi-language BIOS, ASUS EZ Flash 2, ASUS CrashFree BIOS 3
  5. When starting the system, check on the display: ASUS..... BIOS rev. or in BIOS.

    I think i know what the problem is. I need to disable secure boot. However, i can't see an option to do so. I also updated my bios to the latest version.
  9. Have you tried using the onboard graphics (removing the graphics card and connecting the monitor to the onboard)? Just for testing.
  10. It's working! I simply had to reinstall windows! :)
