Problem with boot on B75M-D3P + GT 640

[doop]

Hello,

I need help! My PC doesn't pass the boot startsplash (can only use alt+control+supr) and I can't go inside BIOS. My Configuration is GA-B75M-D3P + GT 640

If I boot with a GT 630, the problem is the same; only the startsplash Logo of Gigabyte

If I boot with only integrated grafics (core i5 3470) the PC works perfect.

If I boot with a GT 240 the PC works perfect too.

The GT 640 & GT 630 works fine because I have another PC and works in it.

¿Problem with the Power Supply? I have a NOX Urano SX 500W. I tried with another Nox VX 550W and the problem persists...

Maybe need BIOS update??

Pleaseee Help!!! Thanks!!!

I am guessing you are having trouble just getting machine running period ?
Sometimes I have had to pull battery to clear CMOS. Pull battery and wait 30 minutes to an hour. Try again.

You can also use onboard graphics or GT 240.
Do install and switch after install to GT 640.

Note HD 4000 would be graphics enabler = no while gt 240 = yes. gt 640 = no also.
Do not use NVIDIA fixes in Multibeast.

You should only need to hit delete key to get into bios. I also assume you are using a USB keyboard.

What is that key sequence you mentioned for ( do you mean control alt delete ) ?
