Hi, I have a similar problem with my ASUS motherboard. I have talked to many people that I work with, and I have read threw many forums. Things that you need to check are as follows:

1. Make sure with a volt meter that your power supply is putting out the correct voltages; also make sure you are connecting all the connectors the correct way.

2. It looks like you have some pretty new components, and although I don’t know the exact stats of what your components are pulling, I would say that 300w is not enough for you application. But if you continue to read 300w is enough to at least cause a POST when you have everything down to the basics.

3. Take everything out, and start with one thing at a time.

**Common problems: Bad Power supply, Connectors not seated properly, connectors where your case hooks to your mother board "power button, reset switch, and LED not being connected correctly.**

One problem that has just been brought to my attention is that sometimes cases *Due to high production rates* can actually be wired wrong. Such as a not so common but existing problem being that the "reset switch" is not correctly wired, so that the board remains in constant reset: Causing a no POST, no boot problem.

SO if you could start by having the extreme basics, such as if you have an ATX power supply only have the 4x and 12x connectors, CPU, memory, and a graphics card installed. Preferably out of the case on a card board box or the static free wrapping the mother board came in. Once you get it to post, just add one thing at a time.

I have to put my disclaimer in.. **Do these things at your own risk!** Just be careful not to damage any components or yourself!

I hope that in some way I have helped you fix you’re no POST/no boot problem. I get my new MOBO today, hopefully I will get it to POST and boot up!
