    Thank you very much for your input, but I can't get back to the BIOS screen. PC just sits there screaming and not booting.

    I tried to remove battery, I tried the reset jumper, but somehow CMOS is still setup wrongly... do you know how long it has to sit without Battery to lost CMOS settings?

    Million thanks for your help!!!

    Dear Gurus!

    Thank you for your suggestions, I found out what the problem was: Even I removed CMOS battery, changed Jumper, removed DIMMs one by one, no luck, becouse..... I forgot my KVM switch is feeding Motherboard even I turned Power off....


    Anyway, I am back online, Millon thanks for all your great help, guys!

    Good nite

You should clear the cmos by removing the cmos jumper and then if it still screams then you might have to change the RAM

Pg. 1-15 in your manual. Do both. Clear the cmos by switching jumper to pins 2&3. Make sure the power cord is unpluged. Use a flat head screw driver to help you lift out the battery. Wait a few seconds. Pop the battery back into it's holder & reset the cmos battery back to pins 1&2. Plug the power cord back in. Boot the Pc & press the delete key to enter the bios. If the Pc is beeping remove the memory & reseat. Try another boot up.
Award BIOS Beep Codes: Repeating (endless loop). Check for improperly seated or missing memory. If beep still continue, only place 1 dimm in slot A closest to CPU. Do not forget to unplug power cord before messing with the memory or switch the PSU to off. Wait for the green light on the board to go off.

Asus P4S533-MX Bios problem

The average life span of a cmos battery is about five years.
The Asus P4S533-MX mother board hit the market in 2002/2003. Suggest you pull the bios battery and check its current voltage. It should read 3 volts DC. Double check the bios jumper. The jumper should be across pins 1 and 2 (This is Normal default setting). Open you're manual to page 1-15 for more information about the bios jumper. (CLRTC1). When in the bios you should set the time and date to current date and time. Save and exit the bios. When you boot your system and the bios auto loads it's self automatically usually its due from a wrong setting within the bios or its not maintaining its voltage. Consider the price of a new battery.

please check the system memory (RAM)
remove them and carefully clean in mouth with a clean A4 white sheet

or change the memory if possible...... and if problem still occur, please check the system processor too...
to check if the processor is functioning, remove the heat sink on the processor and boot the machine placing your finger on the processor chip.
it burns your finger after a short sec. BUT this should be done in a controlled way and after the memory had been tested for

Did you try resetting your BIOS. If you havent then reset your BIOS and try to start the computer again. If it doesnt start then there is problem with memory.
Try another slot(PC has two slots for RAM right) if it still doesnt work then you may have to try replacing your RAM.

Does it have a built-in system beep buzzer? or else you need to connect one. The system beep has a code and will tell you if your video is not connected or your memory is not detected.
Try to make it boot even until the bios screen. Check your video card or your monitor connector. A single beep is a good sign that your motherboard has no problems. hope this helps
