Alarm Sound

By mrtapp1 ·
I have a PC that has a few years on it, and after it's on for about 10 to 15 min, it makes this alarm kind of sound. I thought it might be that it's over heating, but the cpu fan is still working.

Could be the CPU fan isn't spinning fast enough. If the systems is that old its probably a good time to go ahead and replace fans, spinning or not.

Do a general cleanup,by using compressed air and cleaning the fan to cpu and the power supply
Try recreateing the problem after blowing out dust and pay attention to where the sound is coming from,monitor the heating of cpu after being on for a while

What's you MoBO / BIOS? Posible sign of overheating. If that is the case, the #1 reason I see all the time is the fan in the power supply. Which requires a new power supply then.

I had one of these about 5yrs ago and there were 3 different temp settings in the bios, I changed it to the highest temp and never had the problem again. The default is the lowest and after about 10-15 minutes the PC speaker would start beeping at me...

Download and run Mother Board Monitor or a similar program to check what is triggering the alarm.

You should also be able to enter BIOS setup and look on the PC health section.

Just because the fan is spinning, it does not mean that the CPU is running cool enough.

It is possible that the CPU is starting to fail.

Or, that the voltage regulators for the CPU core voltage are failing when they get hot.
