Stuck at POST

[Shipwreck5]

Suddenly, my PC stopped turning on other than for for half a second. I discovered that my old Antec PSU was the problem and replaced it. Now it actually turns on and I can see the POST screen, but thats it. I can't enter the bios or boot menu or anything else. I can only see the POST message which ends with the RAM size and then it just stops there. When I press F8 or any other button it shows that it was pressed but doesn't enter another screen or menu.

Specs:

Xeon x3470

8gb 1333mhz DDR3

Asus p7h55-m pro

Zotac 1050 Ti

And a USB 3.0 card that I tried to remove but still gave the same problem.

Edit: I tried to play around with the RAM sticks and tried to reset CMOS but neither worked.

Have you got a USB in the system ? If so, try removing all unneccesary cables and rebooting

Tried it but no dice
