ok its my 2nd time building a computer but things have seemed to change on these new mobos, first the specs,
the mobo is an asus P5Ld2, equipped with a pentium 4 3.0 ghz processor HT support, also have a seagate 120 gb HD and a 500 Watt Aspire 24 pin PSU

HOWEVER....

The mobo lights up green and the power supply flickers then does absolutely nothing but the green Led on the mobo remains on, , please tell me its a jumper.. if anyone could help, please do because i have no idea where the problem lies... thanks for your help.

Do you own or have access to an ohmmeter? Please use fast reply! You may need to refresh the window to read messages.

I currently have a Asus P5LD2 Mobo, also have a CPU already installed on mobo, 3.0 ghz P4 Chip HT Support, The PSU was a 24 pin Aspire 500 watt. However the mobo lights up green and then turns off when i hit the switch on the PSU but no sounds are audible. Is it the PSU? or the mobo?

It could have been affected, but it may NOT be the power supply. It could be a short from the motherboard to the case.

when setting up the case the board needs to be grounded with those odd looking screws correct?

personally.......i would finish this trouble shooting with the mobo outside of the case on a piece of cardboard to make sure it's not grounding on the case

The screws do attach the motherboard to the case, but sometimes a trace on the motherboard will get grounded if the screw or the case mounting post is too large and pinches one of the board traces.
