New Computer Won't boot

Lenovo Ibm thinkpad t40 cpm
August 11, 2009 at 15:36:52
Specs: Windows XP
I Recently put together a new computer.

Mobo: Asus P5KPL-AM SE
CPU: Intel Core 2 Quad Q8500
Video Card Geforce 9500
PSU: Ultra LSP750
RAM: 2 x 2048 Corsair Dual Channel
HDD: 1TB Segate

I put everything together and tried various methods of booting up but every time, video does not display anything

I tried multiple moniters but no change
I tried with only the built in video but doesn't work
I tried making the Buzzer make beeps by removing ram but it doesn't beep regardless.
I triple checked all connections (USB, Power/reset/hdd LED, HD Audio)

The mobo has a 24 pin socket and a 4 pin socket
i plugged in the 20+4 into the 24 and 4 pin socket with a 4 pin plug. I Tried booting w/o HDD but there is no display.

I also tried resetting Cmos by taking out the battery for 5 minutes

What could the possible problems be?
Mobo malfunction?

Update: All Fans work perfectly, hard drive spins,
The light on mobo turns on when PSU is on and AC is plugged in. Power button turns on computer, but does not turn off computer. To turn off computer, i have to turn off cpu. (the polarities for the on off switch and reset switch are correctly plugged in)

still no display

Did you bench test the board before you installed it.

Bench testing can save a lot of time and trouble.
If you can get it to work out of the case then it should work when installed.....(Placed on a non conductive surface)

One common problem is when a new board is put into and old case, the person installing the board can miss a standoff that's out of place causing a short on the back of the board .

A quick way to test for a short is using a power supply tester.
See if the power supply is working when the 4pin plug is still plugged into the board. This is not fool proof but if there is a dead short on the board the power supply will test bad.....99% of the time. Then unplug the 4pin and retest.

Some boards don't have onboard speakers or the means to
beep.......Does yours????

So the ram could be bad.
Cpu seated correctly?

Sorry this is more questions than answers

"So the ram could be bad."

all parts are new. I will be exchanging the mobo tmrow.

"Some boards don't have onboard speakers or the means to

yes my case came with the buzzer thing. I plugged it into the mobo correctly but it doesn't make any sound. would it be the buzzer problem or the mobo. or both?
