New Build...Won't POST!

Hi...

I'm trying to build a rig for my sister using my old MSI648Max mobo, brand new Celeron D 340 Socket 478 (533FSB), 2X256MB PC2100 (old) and a brand new Radeon 9550. I got a new Antec case with a 350W PSU to put it all in...

When I switch on the PC, nothing shows up on the monitor. It's like the computer is still off. There are no beep sounds from the onboard speaker either. All fans work and the DVD drive spins for a bit but after that, absolutely nothing. I dunno if the mobo isn't recognising the CPU or not recognising the Graphics card. Either way, no signal is gettting through tho the monitor and I can't see if the thing is tring to POST or not.

My first guess is that the mobo has had it. It recently had to travel all the way from Japan to England. Does this sound like a mobo problem?

Or, could the CPU clock speed be too high for the mobo to handle? it runs at 2.93Ghz. I'd really appreciate some help on this as I'm going back to Japan at the weekend and need to have this sorted before I go...

Apologies if this should be in the mobo forum...

Make sure the mobo supports the bank type your ram uses. Single sided RAM is single bank while double sided ram is twin bank. Also make sure you are not going over the bank cap of your mobo too.

The RAM shouldn't be the problem. I used both sticks with the mobo in Japan when I ran them with a 2ghz Celeron then a 2.8Ghz P4. I've tried different memory slot configurations to see if that helps but alas...no joy...
 
The FAQ in the mobo forum has some great troubleshooting procedures for working thru this type of problem. Recommend you move the post to that forum. With those symptoms it sounds like the mobo or PSU.

Processor not supported

That's a Prescott processor. Most older boards won't support them.

The Celeron D is a Prescott P4 core with half the cache disabled and a low bus speed.
