PC Hangs At BIOS Startup Screen

When I start up my PC the bios screen hangs and it doesnt get past the bios screen to boot to windows, I can't press anything so I can't even get into the bios.

It only does this sometimes though, other times it's fine and I get into windows, and other times the bios screen is extemely slow before it goes to windows.

I have looked around in the bios to see if there was a problem with boot devices, and I looked at the rest of my settings and nothing was wrong. I am also running the latest bios.

The motherboard is a P8Z68-V with an i5 2500K.

try taking out alls ODD, SSD, and HDDs and see if it hangs, might be one of those acting funky
