Sorry been at work so couldn't respond. Here's what I've got figured out...

When I turn the psu on, the blue light indicating standby mode and orange/yellow light indicating the system are powered on come on and stay on.

The green light indicating DIMM LED, the memory slot does NOT come on, and when turning the pwr switch it flashes briefly and then turns off entirely.

The red power button only turns red briefly when I press it for start up but then fails Luke everythng else;also when i turn the psu on it's middle flashes green.

Also there is a red power light that comes and stays on with the psu switch just above my gpu everytime.

So I'm guessing this is a memory problem. Is my HD installed incorrectly possibly? I checked the ram and both sticks are installed just fine
