So I recently built my first pc, everything went well. It booted up right away, I installed windows 10, and all the drivers/software that came with my gpu, motherboard etc. The computer runs great, the temperature is good and everything, but I noticed that every once in a while something in my rig will beep. It doesn't happen on start up. When it does beep it only makes one singular beep. I have had zero problems with anything so far, besides this beep. The beep doesn't seem to affect the performance of the computer in anyway, or at least i haven't noticed anything yet. No blue screens, no freezing, everything runs very smooth. It seems like it has been occurring more frequently too. I am using both an SSD and a HDD, with windows and everything downloaded onto my SSD. Any ideas what this beep could be or how I can find out? I have a hunch that it is coming from my hard drive but I'm not sure.
