Hi there,

I'm having problems with a ga-p35-ds3 motherboard after putting together a system for a friend. The specs are;

Core Duo 2.4ghz E2220, Geforce 9800gtx, 2gb ram, 250gb hdd, Antec neopower 650W PSU

Trouble is the thing won't turn on, the first three or so 'phase LEDs' by the RAM slots light up green, then there appears to be a yellow colour around 4, and red on the last ones. It's difficult to see exactly which leds are which colours because they light up only for a split second- then nothing.

I'm trying to find out what the LEDs mean, as they should tell me whats going wrong, but I can't seem to find it in the manual...

The chasis intrusion header has not been connected.

I've tried with 1 stick of ram, no luck.

The USB devices plugged in work, so there must be power running through the motherboard.

Maybe somebody here knows what each of the Phase LEDs indicate, so I can find out what the problem is.

Help would be much appreciated, thank you in advance.
