I have just built a new computer which consists of:

Asus M5A78L LE

AMD Phenom ii x4 965

2x Kingston Hyperx Blue 4GB (Each)

And then a cheap power supply that i am planning on replacing soon

When i started it up all the fans stated and the led on the motherboard starts, but then there is beeping and bios dosent come onto the monitor. The beeping consists of what i believe is 1 long beep, then 3 short beeps and then a final short beep which is a couple of seconds apart from the rest.

From what i have read on other sites i was lead to believe that it was the RAM that was at fault, so i tried each of them on there own in each of the slots and there was the same problem every time. I do not believe that these could both be damaged as they were brand new and i was static free.

Can you please help me and give me some advise on something else to try.

Thank You
