Asus will not turn off after shutdown

Situation Remedies If you have encountered this error and would like to fix your computer, here are some remedies for each situation:
CMOS Battery Not Functioning Properly: If you suspect your CMOS battery is not functioning properly you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all settings are lost, you can usually get them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computers manual or tech support to remove your battery. Take down the CMOS batteries information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have remedied the problem.
Your BIOS has Been Updated (either by you or possibly a virus): If your BIOS has been updated recently, your CMOS settings may have become reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.
The Computer Was Shut Down Improperly: Sometimes when running MS Windows, if you shut down your laptop or desktop without first properly shutting down your operating system it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer before turning off the power. Usually this entails going into the Start Menu/ Turn Off Computer/ Shut Down. If you received the error, shut down the computer properly, if this is the cause of the error, the error message will not return.

It is in your bios this motherboard has been known to have isues with the bios chip.I am useing this motherboard and have been lucky I did not get this problem you are haveing.You may try flashing to the curent bios 1903 geting the download from the Asus site.

Extract
Then remove file
Rename file to P5LD2.rom
Put renamed file only on three and a half floppy disk
Reboot Holding alt F2 at same time
flash will start

If you do not feel safe doing this then you can get a new bios chip from asus with the 1903

Good Luck
Also make sure you have no air gaps on your heatsink to proc this will cause the pc to heat up and shut down.

Try to remove the processor, then clear it with contact cleaner, then plugin it again..

There isn't beep : Processor, and long beep is memory..

Hopefully this be of some help/idea..

The CMOS, which stands for complementary metal-oxide semiconductor, is the hardware component of a computer that supports the BIOS, or basic input output system. The two terms are often used interchangeably, and the two technologies work together to perform the same basic function. They maintain the low-level settings on a computer, letting the computer know, even before the computer's operating system starts, what kinds of hardware the computer has available, such as hard drives and video display adapters. A special battery located on the computer's motherboard powers the CMOS. To reset the CMOS on a Dell computer, briefly remove and then replace the battery

1. Turn off the computer. Disconnect all cables and detach all devices, including USB devices, from the computer. Press and hold the computer's power button for 10 seconds after it has been unplugged. This grounds the system board.
   
2. Step 2 Remove the computer cover. All Dell systems have a cover panel on the chassis that you can remove so that you can access the system's motherboard and internal components. For some Dell computer lines, such as OptiPlex, the computer cover is held in place by a release latch located on the back of the computer. Pull the latch to release the cover and then slide the over up and away. Other lines, such as Dimension, have large, slotted thumbscrews. Turn the screws counter-clockwise until they disengage from the chassis, the slide the cover off the computer. Dell computers often ship with the computer's user guide in CD form or with the guide pre-loaded on the system's hard drive. You can locate the instructions for removing the cover from your particular system in the user guide.
   
3. Step 3 Locate the CMOS battery on the system's motherboard. CMOS batteries range in size from size and thickness from about the size of a nickel to about the size of a quarter. The CMOS battery will generally be labeled CMOS on the motherboard and will be the only battery openly exposed on the motherboard.
   
4. Step 4 Remove the CMOS battery by prying it gently up out of its socket. The sockets are specifically designed to allow the battery to be replaced.
   
5. Step 5 Wait 30 seconds, and then replace the battery in its socket. This will reset the CMOS. Replace the computer cover to complete the process.
