Question Gigabyte GA-78LMT-USB3 rev 4.1 continuous beeping noise

Hi there,

I wonder if someone can help. My motherboard has been making a continuous beeping noise for the last two days - since I had to do a complete fresh Windows 10 install after an unstable update completely crashed my machine.

According to Gigabyte support a continuous long beep means the memory not correctly installed, but it was working fine before the install. And was only touched after the board started beeping.

I've tried taking the memory stick out and putting it in another slot, didn't work. I tried testing an old 4gb memory card that I know works fine in all of the slots, still beeps..

I've even tried removing the CMOS battery for an hour to reset the data, but nothing I do makes any difference.

The board was launched before Win10 came on the market, so it doesn't say whether it's compatible or not, but it was running Win 10 since it launched and only started making this noise yesterday afternoon after I had to reboot numerous times to install a clean copy of the OS - computer froze after 5 mins use, so it took ages to get it to stay on long enough to do anything.

I'm not expert, but I can't see any glaring problems in the speccy excerpt below, could somebody with a bit more know-how have a look and tell me where I'm going wrong?

Little to go on...but it sounds like it could be an overheating issue :
1.) Have you PHYSICALLY CHECKED that all your fans (CPU, CASE) are properly connected to the motherboard and running?
2.) Have you monitored the fan speeds and system temperatures in windows? (SpeedFAN or similar)?
3.) Have you gone into the BIOS :
a) and checked the fan types and speeds there?
b) to make sure that the BIOS didn't ''flip a bit'', and now a fan that isn't there, isn't working or is under speed is causing a warning?

Please post the ENTIRE SYSTEM SPECS.
Please post the MEMORY BRAND, MODEL and MODEL NUMBER.
Please post BIOS HWMonitor pictures or screenshots of any monitoring software in Windows.

Hi ChevetteSCx,

Thanks for helping me with this, I haven't the first clue about anything hardware related.

I have followed your suggestions, and soon as I opened the BIOS screen I found that the system fan speed was 0 RPM. So I think you've solved it. The continuous beep must have been some sort of alarm for the fan and not memory - even though Gigabyte support did say a continuous beep was caused my the memory card being incorrectly inserted.

I tried plugging the fan cable out and putting it back in again, but no joy. Unfortunately I don't have a spare to test whether it's the fan unit, the connecting cable of the fan unit, or the socket on the motherboard that's gone, but at least I know roughly what the issue is now.

Would constantly rebooting my PC yesterday cause this to burnout?

Thanks again
 
Gigabyte Support was right. A CONTINUOUS LONG BEEP would be memory, but, then your system wouldn't boot, AT ALL!!

I am assuming that the CPU_FAN is reading around 2,800RPM?
So that means that the SYS_FAN is hooked up to some sort of three-pin case cooling fan? At the rear?? Above/Below the PSU???

Physically examine case fan to see if it is spinning. If not...obvious problem. Check to see if the fan is blocked, or just EXTRA DUSTY. You could try manually turning it, to see if will spin up...could be a worn bearing (listen), if so...REPLACE FAN!!

If it is spinning, but you aren't getting a ''feed-back'' RPM, then...REPLACE FAN!!

Either way, don't do any intense computation (gaming) until it is REPLACED, as it is probably the only active cooling in your case (besides the PSU Fan). Convective cooling WILL NOT DISSIPATE HEAT FAST ENOUGH (under intense use), so you could overheat the case and have other components shut down.

And, NO, the ''continuous rebooting'' yesterday from the ''fresh install'' of Windows 10 should not cause any physical, mechanical failure. But the failed ''system update'' could possibly be a result of the fan alarm causing issues with system stability. Also, it is more-than-likely a 120mm ''sleve-bearing'' type fan, they don't last, and they can crap out without notice...
