Is it a RAM or a MOBO issue??

[NG 95]

Hello everyone

My pc's specs are:

Mobo: asrock h77 pro4/mvp
CPU: Intel i5 2400 series 3.10 ghz
GPU: AMD Radeon HD 7700 Series
RAM: Corsair xms3 1333 mhz 4gb DD3 x2

So I got this PC from my father and it had 4 RAMs of the same type in total, long story short it was giving me BSOD 'cause of memory problems.

I removed the faulty memories and the PC now works just fine BUT bios will only read half of my memories (2gb 666 mhz each).

Also my RAMS are running in single channel. The reason for this is that if I switch them slots the PC won't boot, even if I put one on the others slot (RAM no1 which was in slot no1 in slot 2 and RAM no2 in slot no1)

If I put the faulty RAMS back on the PC, it won't boot at all now (before I removed them it would boot up and it would just give me BSOD).

This whole situation looks really strange and I don't know if its MOBO related or if the 2 last RAM sticks are dying.

Also the MOBO doesn't beep at all, but then again I don't know if it was beeping brand new.

Any tips?

Thanks a lot in advance and sorry for my bad english.

Alright so I cleaned one of the working RAMS and the RAM slots in the mobo

and now the PC boots while the RAMS are on dual channel mode, though the RAMS are still being read half.

So now there are more chances it's a RAM related issue right??
