One of my computers is following a strange behaviour since some weeks. Sometimes 1 hour after power on, sometimes after 5 days, it suddenly starts beeping. To be exact, it is a continuous beep (it really sounds like an indefinite pattern of "beeps" without any separation among them).
My CPU is P4 3.0 hyper; the motherboard is Aopen AX4PE Max, and I think there is a led next to the CPU that begin to flash when the beep starts - I am not sure and I really don't want the beeps to start ;). I have checked out the manual and forums and I have find nothing about this in AOpen.
More generally, I've been told it can be a memory or graphics card problem. I don't think it is a memory problem, as I can work with the computer - and I really use every piece of memory it has. I'm monitoring CPU and case temperature, but beeps appear even when 40 Celsius, so I would discard that problem.
The graphics card is an nVidia Riva TNT2 M64, which I believe is AGP2. I really don't know if the motherboard supports that, but it works...
I would really appreciate if you can point me in the right direction. When beeps appear the only way to shut them up is shutting down the computer. If I restart the computer just after shutting it down, there are no more beeps. It is annoying - and noisy!
BTW: I have disabled heat alerts in BIOS (maybe Windows put it on?) and set fans to 100% in BIOS too.
