First Build, NO BEEP or POST ! Please Help!

[Turkle]

Hello,

I have just build a new computer last night. The first time I tried to boot there was no beep and the monitor said no signal detected. So, at first I tried other pci-e slots, that didn't work so i tried my older 6600 gfx card that did not work either.

I had the triple channel ram sticks in the black ram slots. I left only one stick of ram in the first slot. Tried to boot like that but I still had the same problem. I moved the ram to the next slot, the orange one.

This time it did work and so i just slotted them in the orange ones. It all worked fine, I got a single beep and even played crysis. But this morning i have the same problem! I did all the same steps again but i cant get the pc to boot.

Please help,
Thank you for reading.

The parts i bought are:
Asus p6t deluxe motherboard,
core i7 920 2.66ghz,
g-skill NQ PC3-12800C9 1600MHz triple channel ddr3,
xpertvision 9600gt 1gb gfx card - this was 2nd hand, but it worked fine on my previous pc,
be quiet 1000w
samsung spinpoint f1 1tb hdd.

Have you checked all connections to make sure they are seated properly? Some of them can make you think they are seated when in fact they aren't. It is difficult to tell sometimes.

i have checked them many times. They seem like they have seated properly but as this is my first build i cant really compare it to anything else.

Everything works though, such as fans, dvd drive, hdd so they must connected properly ?

any other suggestions plz.

Use the orange ones first. Pull the ps connector, pull the atx connector. Replace the atx then the power suppy connector. boot.
