Can't reach BIOS


Dec 1, 2009
Hey guys, I have a Gigabyte 880GM-USB3 and the problem is I recently switched to this motherboard since my previous motherboard failed. Now every time I start the PC it doesn't show me the start up (the screen from where I can enter bios settings, etc) it directly takes me to the login screen. I feel as if I'm locked out of the BIOS. What do I do ?

The processor is working and the OS is booting, I tried re-installing windows 7 but the computer doesn't boot into the start up screen so I can't re-install the OS
