New system build turns on but won't boot, not even the bios! help

[snbase2]

This is my 3rd system build and having a very irritating problem. I bought a ECS G31T-M motherboard along with a e8500 processor and a 1gb stick of ocz high performance premium module DDR2 800mhz. When i start it up the system hangs. It doesn't beep but all the fans and lights go on like normal. It goes to the boot screen and lists my cpu and memory but stops there. It says to press (DEL) to enter bios or (F11) for BBS popup. But nothing happened when i tried both. I tried clearing the cmos by both reseeding the jumper and also removing the cmos battery and when i did this it no longer had the option to boot into bios(DEL). This is really getting frustrating and don't know what the problem is.
