BIOS beeps when starting PC after it has been receiving electricity a while before

Ok so, my computer is connected to an electricity adaptor with many sockets. I switch that adaptor off when I'm not using it.

If I start the electrical adaptor and then I start the PC, the PC goes to windows without trouble.

The problem comes when I connect the electrical adaptor a while before (for example for charging the battery of my cellphone or to switch on a desk-lamp). While it's connected, the pc is receiving electricity even if it's not being powered on (nothing strange). But then, after a while, I just start my computer and the motherboard makes this sound and it doesnt start:

4 short,1 longer, 3 short
beep-beep-beep-beep-(brief pause)-BEEEEEP-beep-beep-beep

Always happens after the pc has been receiving energy for a long while without actually being turned on.

The solution that I found is to switch off the PSU of my PC after I shut down the PC. But I want to know what's the source of the problem, this shouldn't happen. I know it has to be something related to the energy.

It's a brand new pc and I made sure to connect everything good on the motherboard:
Motherboard is Gigabyte 990FXA-UD3
PSU is Corsair 750W
GF 660 ti
8 cores
8gb ram in one stick

Thanks if you can help me to find out the source of the problem.

If for example you shut down the PC now, and in 5 mins turned it on, would it beep?

This sounds like a surge suppressor?

It also sounds like a crappy one. I'd suggest trying a new one.

Nope, it wouldn't beep if I cut the energy for a few mins

I mean without cutting the energy, just shutting it down, without touching the power supply, and in 5 minutes turning it back on again.

Ok, I don't know what to think anymore

I tried again now. The PSU was on the 0 (zero) for various minutes and I turned it to the 1 (connected) and started the pc and it made the sound... What can it be? >.<

BTW, I was wrong with the sound; the sound is this

8 short; (brief pause) 1 long+3short

beep-beep-beep-beep-beep-beep-beep-beep (pause) BEEEEEP-beep-beep-beep

8-beep and 1-long-3-short-beep both point to RAM errors.

Run memtest86 overnight.

What I meant was shutting down the computer, leaving PSU on 1, and after 5 minutes turning on the computer normally.

Why do you have to turn off the PSU anyway?

I think somethings wrong with the RAM indeed. I Installed memtest86 on a bootable USB and i started it.

The test has restarted my computer at least 5 times, when it reachs the test number #3 (takes like 20 secs to reach there) it restarts the computer and starts over again.

It'll try to move it to another ram slot...

thanks for your answer

Faulty RAM or motherboard.

Memtest isn't even supposed to make the computer restart!

Put it in another slot (just as you mentioned), if it restarts on every slot then either the memtest installation is corrupted or the RAM stick is bad.
