I have a K8N-VM mobo. I flashed it up the other day. Initially it worked fine but when I tried to go into the bios settings it hung. I rebooted and got the Bios Checksum error screen. I shut down and changed the battery and carried out the move jumper to blank bios routine. I then used the mobo cd to try and reload the Bios on the auto recovery. It seemed to be sucessful but when I rebooted it did the same Bios checksum routine. Next I found the latest bios on line, renamed it to same as on mobo CD and burnt to CD and tried to use that to recover. It seemed sucessful however again on reboot bios checksum problem. Finally I bought a replacement Bios chip and fitted using antistatic precautions. Still the same problem.Is there anything else I can try?

make sure battery is in mother board make sure the fuse is good and in mother board make sure aluminium tower is clamed on black chip to mother board and also make sure fan is cecurelt tight on mother board.

go bios change the sequence pci express first then on board vga >f10> yes

i hate to tell you this but it seems your pci or in your case agp exp.slot is most likely melfunctioning if your card works on another computer then that may be your problem one thing you can try is take the mobo out and let it sit for a few days or call msi them selves and they may replace it for you for free they are good about that i have the k8n neo4 with a 7950 1g pci.e with same problem and thats my pci e not working

Check the memory and/or vga card

The one beep is usually normal for most computers. Is your Video card seated correctly?

4 beeps Refresh error RAM is not refreshing correctly. Reset the refresh values in the BIOS or reset the BIOS.

Hello nikunj_bhatt:

I know that you have a hard time with English.
But to get your idea and problem we need to clearly understand what you are doing and how. Have someone to help you with this English.

I will attempt to help.

Make absolutely sure you have the correct bios set up for this mother board.
If you put in the wrong bios recovery, then the problems cannot be corrected and may render the mother board useless.

However, if it was the correct one, then it seems that this needs to be done again. Make sure you have read the instructions which comes with the data bios set up disk and program.
Thanks,
Hope this helps.

Have you tried a secondary PSU? (though it sounds like your motherboard needs replacing)

Download WD's software to test & setup drive. Try windows install again.

OK lets see here! Make sure your CMOS jumper is set properly on the board(Set to Normal) or Did you configure your bios after flashing the bios(going into bios and Load Optimized Defaults!)? or I don't think it would be another device in the system, but you can try troubleshooting by starting up with only what you need to run the machine (Mobo, memory harddrive, keyboard and mouse) then one by one adding devices back! or Did you have problems like this b4 you flashed the bios! Try flashing the bios back to an older version! post back if anything new or if i'm way off! Good Luck regards, babb
