Small Problem

[Captain Kirk]

Hope one of you guys can help.
Recently when turning on my computer, it won't start. Nothing comes up on the screen and the screen itself goes into standby. I don't hear any hard drive movement, but the lights on my cd/dvd drive flash.

Is it time to replace the h/d, or is it another problem??
Thanks y'all

I'm water-cooled, so no fan. all my other fans start up though, and the pump (I think, it's very quiet). I have a pci card I could try.I'm using an A8n-sli deluxe, so no onboard video, but I do have a PCI card I could try. It's a bit tight in my case though with 1/2 inch pipes.

Right, finally tried a PCI card, as my computer now refuses to post at all. I also tried just one stick of ram. I don't have an internal speaker, so getting no beeps.
I have noticed that my southbridge hsf doesn't work. It may have been like this for a while. What are the chances it's a motherboard problem. I think my psu is ok as I managed to boot another system with it.
