Motherboard wont post. This is a MSA2-6100V. Have isolated board to check for shorts, removed and tried posting with each stick of ram,cleared CMOS. Problem is CPU fan runs as soon as you switch power supply on and no post. No beeps from my on board sys. spkr.Help Please.

The board is not posting. Try clearing the CMOS by removing the battery on the motherboard for 5 minutes.
Next, check the RAM you have installed to make sure it is correct for your motherboard. Next, disconnect all drives and try to boot.

Hello you can download the manual here:

http://support.asus.com/download.aspx?SLanguage=en&p=5&s=13&m=P5BV-E%2fSAS&os=23&hashedid=zuljCoD6sSH3WpYx

By selecting your windows system.
Open the manual folder and click on global for download.
You need adobe reader to read the content.

This is usually a hardware problem, Video card, power supply, memory sticks or mother
board. To nail down the problem, try the following workarrounds:

1. Does this computer work well before? If yes, what new hardware did you install recently? Remove it and try.

2. Insert one ram module, and turn on the
computer, if the computer POSTs or you hear beeps, try to add one memory
stick each time until you add all your memory sticks.

3. Clear your CMOS by removing the battery or short the jumper.

4.
Swap your hardware from the motherboard, for example, reseating your ram sticks, move video card from PCI slot 1 to PCI slot 2, etc.

5. Reseat your processor, check the CPU for damage.

6. Verify that you have all the power connectors connected properly.

7. Make sure the power supply is working, even test it on another pc.

Remember
to restart your computer after you try any of the above steps. If all
the above does not work, it is very possible that your motherboard is
bad.

Post back what is going on.
Good luck

If it's 1 long and 2 short beeps it's a video controller error. Check the warranty status and RMA if possible: http://www.supermicro.com/support/rma/

If it's 1 repetitive long beep, it means that no memory is detected. Try booting with only 1 stick of RAM. Try different dimm slots to see if you can isolate the issue. You may have a few modules that do not want to work together, a bad stick of RAM, or a defective dimm slot.

It may be that your motherboard is dead. I have had this problem before. Here are some things you can do to troubleshoot:

Remove video card then plug back in or try alternative video card if you have one.

Isolate each memory stick in your RAM. This may identify RAM problems.

Try a different power supply in your PC or at least reconnect every connection for your current power supply.

Try clearing the CMOS by switching the CMOS clear jumper

How long did you have cmos cleared. I would try to set Cmos clear jumper and remove Cmos battery for 30 min to an hour. Also with no power card in system try to power on to drain some of the capacitors. Then see if you can boot with battery back in. I would also try removing any PCI devices and ram. If you have multiple sticks of ram try 1 at a time. If it post after the cmos I would check for a bios update. I believe that MB had an issue with some PCI cards that would cause that error that was fixed with a bios update

Remove and reseat your RAM, or replace RAM

This code usually refers to a Video card or RAM issue. Try reseating both the video card and then RAM to see if it fixes the problem. If not then try removing the video card and rebooting. If the system starts without the beeps then you'll know the video card is bad and you can replace it. If it still beeps then try removing the RAM one stick at a time, rebooting after each removal. When it boots you'll have the bad RAM stick isolated and can replace. Hope this helps.

The POST error message (beep codes) indicated the BIOS/CMOS battery is flat and needs to be replaced.

Windows is holding ram memory..........try knocking downing page files/storage not used.......use the task manager to manage ram better.......disable the junk? or freeramxp.load the barebones.........<<suggestions)))> solutions of the cuff...check that the ram sticks are OK....for the boards . check the boards. for any damage cracks/leaning caps etc.....for a system not to pass post! well.......is the Motherboard up to it......
Or this might be: "Memory errors status is now read from the BMC. Because this was not done previously, error status bits have piled up in the BMC and the first time you boot with this BIOS you will probably get a message saying all of your memory is bad (POST error 8601). To clear his status, enter setup/advanced menu and select the 'memory configuration' option. Enable 'memory retest' at the bottom of this menu and you will remove the error message. 'memory retest' option will be reset to 'Disable' in the next reboot.

"Remember to Clear CMOS after each BIOS update. Refer to the Hardware Maintenance Manual or Product Manual for procedures to Clear CMOS."

Good luck!
Please rate me.
Thank you.

Try RAM with a different speed. My 800 mhz RAM didn't work until I installed 533 mhz RAM and adjusted to 800 mhz in BIOS. Newly built PC, default must be set as 533 mhz because I reset the CMOS and still couldn't POST to BIOS. Only taking out all RAM gave me any sort of audible error code. Luckily I found some 533 RAM before I RMA'd the board.
