New computer problems..Counts to 1050 Mhz+wants me to change it in bios+SuddenShutdwn

[GreyFox]

I finally got my new case, and by borrowing a mobo and processor fan (which are both practically unused) from a friend, I built my computer yesterday.

Here is the specs:

Asus A7N8X-E Motherboard
Thermaltake Volcano 11 Processor Fan
AMD Athlon XP 3000+ (2.1Ghz)
1Gb PC3200 TwinMos RAM @400Mhz
ATi Radeon 9600XT 256 Mb.


Here's what it does. I boot it up, and it counts the Processor speed and RAM amount, and it says the processor speed is at 1050 Mhz, and it gives me a message saying that the computer wasn't turned off correctly last time, and that I need to change the processor speed in the Bios.

So I enter the bios setup, and the FSB is at 200 Mhz, as it should, and the Multiplier is at 10.5, as it should too I think.

The Processor temperature is at 39-44 degrees Celsius or so.

- When I save the bios, the computer turns itself off.
- After an amount off time, the computer turns itself off.
- Sometimes, it turns itself off immediatelly after I turn it on.

All fans are active etc...

Help?
