Asus P5QL Pro Motherboard bootup failure

[serenadesx]

Hello.

I put together a machine a few weeks ago.

The parts inside are:
Asus P5QL Pro Motherboard
Intel Core 2 duo 775 CPU
Asus EN7200GS VGA
2 x 1GB Fatality OCZ RAM
Antec Neopower 550W Power supply
2 x dvd-r drives
160 GB Hard drive

The thing is, i put all of these parts in an old computer case, and everything worked fine. However, when i got a clear acryllic case and moved everything in there, I get these messages at boot:

CPU fan error!
CPU over-voltage error!
New CPU installed! Enter setup to configure your CPU.
Chassis intruded!
Fatal error... system halted.

I did not replace any CPU or Motherboards. Everything is same, except that i changed the case from a metal case to a acryllic case. I have been googling for 8 hours yesterday, and nothing appears to resolve my problems.

One way to boot it up is removing the battery on the mobo, then pressing F2 to load default values and booting up to windows. EVerything works fine inside windows, until i restart, then i get those abovementioned errors again. Does anybody know what is wrong? possibly the case?

Two things I would look at are the motherboard mounting and the BIOS.

It is very possible that your motherboard is short circuiting. Unmount it and be careful when putting it back in the case.

The BIOS is the other thing to look at. You may need to update it to the latest version.

It's still possible that something else is going on but these should be addressed first.
