I installed over 20 pcs with MSI mobos some time back in a local school. After the Summer break of some 2 months many (probably about a dozen) refused to boot and access to the BIOS was not possible. I guessed it was a CMOS problem. Could that be due to the on/off switch on the PSU being left on for the holiday and causing battery drain? The power to the room was switched off.
I replaced batteries and still they did not boot. I removed the only ram chip and rebooted - a seemingly pointless exercise! Then replaced ram and in all cases the machines booted up fine straightoff. So this was a consistent cure for the CMOS problem.
So this post is really a piece of information that may help others. Not sure whether it is peculiar to that MSI mobo but its worth a try if you meet the problem.
My questions are: Why the battery drain? Is it due to PSU being left on? Can't think of any other reason.
Why then does removing the ram, booting and then replacing it work?
Hope this helps somebody and would be intrigued to know what was going on.
Thanks,
