Windows 8, pereodic beeps

[Darkswormlv]

Hi!

This morning i powered on my pc, everything as usual - it powers on, logs in and then it just starts beeping pereodically.
Sound works, there is no flaw to the computer except the pereodic beeping, it is coming from the front and the back audio port so it might be some software, but 

i already tried killing all processes that arent essential to windows - no luck.

ATM i am trying to find the cause and doing a virus scan in a moment. 

If you have experienced this problem, please let me know how to solve it.

Edit: the mixer shows that no sound is being emmited, altho when i first powered it on and checked, it did for like 2 beeps. I guess it's getting masked somehow.

Edit2: a sound driver reinstall does not help.

Edit3: it seems that the beeps are under System sounds in the mixer.

 

Edit4: Problem Solved, Lesson learned - always unplug second keyboard after use, if it falls shit will happen

Firstly, could be your soundcard or motherboard?

I dont think so, it only starts when i log into windows.
