No post - if not a connection, usually a failed component (dead/dying PSU, bad memory stick, bad video, bad cpu, bad motherboard, etc)

Warranty? This is almost new machine isn't it?

If not, I like thoughtful troubleshooting like:

Thanks for the reply and suggestions. I have ordered a new (and bigger)power supply, and a new mobo. I will let you know if they fix the problem. Computer 3 weeks out of manufacturers warrantee (of course!!)
