Question PC wont start when using Dual Channel RAM

[MrFlare]

SPECS:
Motherboard: Biostar G41D3C Ver.7.x
CPU: Intel Celeron E3400 2.6Ghz (2 Cores)
RAM: G.SKILL Value Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)
Previous RAM: 2GB DDR3 ADATA 1333Mhz (AD3U1333C2G9-S 2GX8 U-DIMM)

Recently I bought a ram upgrade for my old PC, the PC only had 2GB of ram Single Channel. I got 2 new ram sticks of 4G to make 8GB in Dual Channel.
The problem is, the PC wont boot at all when I use both sticks at the same time. It just freezes in the post screen or goes all blank(like if the video signal was getting unstable).

I already tried using each stick individually and in both slots and they work fine, the problem is when I use both slots at the same time. The motherboard is supposed to support 8GB of ram(each slot supports 4GB stick). Im not sure but this could be a voltage issue, or maybe I have to enable a specific option in the BIOS for dual channel support(wich I havent found yet). The MOBO also supports dual channel.

Any tips or advices are welcome.

Try updating the motherboard bios. That can improve your RAM compatibility.

Already did that, there is no change, just to make sure I updated chipset drivers as well but that didnt change anythin.

UPDATE:
Something weird happened, I used the old 2GB stick and a 4G stick at the same time and it booted without a problem. The problem only seems to happen when I use both 4GB sticks.

Any idea why this is happening?

You wrote, "got 2 new ram sticks of 4G to make 8GB". I suggest you list part number or link to memory.

One of the 4gb sticks may be faulty.

One of the 4gb sticks may be faulty.

I already tried both 4Gb sticks individually and they work fine, I think this can be a problem with the motherboard itself, or maybe the PSU is not working correctly and the motherboard is not getting enough voltage.

Another weird thing is, the first time I tried using both RAM slots, it worked and I got 8GB of ram (I didn't have access to all ram because I had Windows 7 Home 32bit), and after I rebooted to install windows, the problem started to happen, maybe the problem can have something to do with the bios? I will still try to get both 4Gb sticks to work in the meanwhile.
