No Display on Screen New Computer Build

Nothing on screen first boot up on motherboard.
Plugged everything into correct slots according to the manual. Goes through a series of codes on the Q-codes and ends up on 99 "super IO Initialization" then when boot from direct key or pressing "del" comes up with AE "legacy boot event"
The LEDs next to the 24pin connector there are two that are lit up which are LEDBOOT and DEVICE LED

First i tried building it on the motherboard packaging box first still the same put it into the case same thing. Tried 1 stick of RAM also putting it in every slot. Have tried moving the GPU also tried VGA, DVI and HDMI cord to 3 different screens these cords and monitors also work for other computers. Have double checked all cords to motherboard including all power cords 24pin, 4pin and 8pin. Also the periperal connector that supplys extra power to the GPU through the motherboard. All fans are working on the case also GPU and CPU heatsink. Keyboard comes on with all lights and works when pressing keys on keyboard the hard drive light flashes. The BIOS on the motherboard is 0508.

Thanks heaps in advanced 🙂

Welcome to the Republic of Gamers forums, Cozza2121.

I need you to recheck the QLEDs for me. If you look at the motherboard vertically, you'll see four of them in this order Boot Device, VGA, DRAM, CPU from top to bottom. You mentioned that 2 of them are lit. Which 2 out of the 4 stays lit?

Looking at it vertically the two that are lit is VGA LED and BOOT DEVICE LED.

In which slot did you install the GT 640?

Does the GT 640 fan spins up and stay spinning when you power on your system?

Could you confirm the bios version that you are using? To find this look at the white sticker next to the SATA and 24 pin PSU connector.
To help us help you - please provide as much information about your system and the problem as possible.
