Does 4 beeps mean motherboard issue?

[RichzHart]

Hi, I have a pc that doesn't boot, after some diagnosis, i got 4 beeps from mobo speaker. I then read about the different beep means. According to what I see, 4 beeps mean a motherboard bad timer. I don't know what it mean but it seems that the motherboard is the issue. However, I do not know whether the CPU is working. Does the 4 beeps just mean that the CPU is still working or the beeps only report motherboard issue?
I'm using an MSI board LGA1150 socket with i5-4660

What are full system specs? Mobo, RAM, PSU?

Have you tried booting with only one RAM sticks inserted in the slot (and others one by one if you have more than one stick of RAM)?
