Dell Inspiron beeping 5 times

I have a Dell Inspiron 14 that I bought in early 2016. About two weeks ago, my computer starting beeping 5 times when turning on and continuing to beep once I log in and use my computer. I called Dell who had me run some tests and the beeping stopped. Today, the beeping started again. After searching online, I found that it could be a CMOS battery failure. So I bought a new battery and replaced it. Beeping still occurs. A few things to note that may/may not be important:

- My computer still starts up and operates normally. I can browse the internet and everything.
- When I play audio out of my computer the beeping stops.
- I did notice a while back that my clock on my computer was running about 1-2 minutes behind but didn't think much of it. After changing the CMOS battery, the time is back to normal. So I know the battery itself is working properly or at least better than the old one.

Any other suggestions on how to fix the beeping? Thank you!
