I just transferred my computer components to a new case, it had previously been working fine.

Now whenever I turn it on, the fans/etc. turn on for approximately 1 second, then everything immediately shuts off.

Here are my specs:
Intel Desktop Board dg33fb
Intel Core 2 Duo E7500 @2.93 GHz (stock) w/ stock cooler
Diamond Radeon HD 4670 w/ Zalman VF900 cooler
Patriot PC2-6400 2GB RAM (2x1GB) PSD22G800K
Thermaltake 500w PSU
Maxtor 320GB HDD

I have already determined that it is not a PSU problem, as I tried it with two different PSUs and the problem persisted.

I also tried removing all components except the Processor/fan, and then the CPU fan did start up and stay on, and I got the BIOS code of 3 beeps.
Which means:

3 beeps - Base 64 K memory failure

* Reseat the memory.
* Make sure that the contacts on the memory and the socket are clean.
* Try removing one bank of memory modules at a time. Note: Some systems might need to have a memory module in Bank 0.
* Try using memory modules from the same manufacturer with the same part number and speed.
* Check for a faulty memory module by trying the memory in a known good system.
* Trying known good memory in the system.
* Check the power supply and check for power fluctuations.
* If the steps above do not resolve the problem, the desktop board may be defective. Try a different desktop board.
This made me think that maybe my MOBO wasn't screwed, so I tried each of the 2 RAM sticks individually, and it shut down as before.


Then I tried known good RAM from another computer, still nothing.

I also tested the MOBO battery with a multimeter, and it was good.

So unless someone knows anything else I could try, then I suppose I need to buy a new Motherboard.

there must be something in the memory socket. also remove from case and do it on a bench to eliminate any grounding issue.

also, you could reseat the CPU

Sounds as if you may be shorting to the new case. Be sure your case standoffs are in the right place and you are using spacers o nthe screws if you have them.
Get your facts first, then you can distort them as you please.
