[Solved] Deciphering 5 Short Beep Bios Signal on Gigabyte Aorus H370 Gaming 3 with Intel Core i5 8400

I do not know if this is the right section, but maybe someone will be able to help.

Yesterday I moved the parts of the computer to a new case (Raijintek Zofos evo), aside from the fact that the correct connection of everything is a big problem, a bios signal appeared, as in the title, and I can not figure out what could be the cause.

The motherboard is a Gigabyte Aorus h370 gaming 3 wifi with a proc intel core i5 8400

I don't know exactly what the five times signal means (short signals in succession), but it probably has to do with a processor error, only question is what is the error and why?

Problem solved... Or at least with the bios beep. It turned out that in this version, the bios issues this signal when it defines a processor error. It also turned out that an unplugged monitor is also treated by the bios as a prock error.

However, not to make a million topics, I'll ask one more question about the connections to this motherboard.

Well, I have two strip led headers (RGBW) on the motherboard, they look like this


I also have a cable from the remote controller, which has four inputs to the pins

Now a question, from which side in the cable I will have 12V, because on the motherboard it is nicely described, but on this cable for nothing I can not figure it out. In general, starting this contraption is a feat

Thank you all for your interest. Both the problem with the bios error has been resolved, as well as my second question about the remote controller connections to the board. Logically, I figured that the cable with the gray accent must be the voltage cable in this harness, while the rest are signal cables.
