Problem with my new Ram

[Touk97]

Hello everyone!
So my pc has the following characteristics:

OS: Windows 7 64-bit
MOTHERBOARD: asus PH755 - m le
CPU:Intel core i3 560 @3.33Ghz
RAM:Kingston DDR3 - 1066Mhz 2Gb (New RAM: Transcend DDR3 - 1333Mhz 4gb)
GPU: Nvidia GeForce GTX 650

Well, I wanted to add some more RAM and i bought that transcend which i mentioned to add it and have a total of 6gb ram. When I placed them both (i have to slots only) my pc was crushing at the start when the model of the motherboard was displayed. Then i placed only my new one and then it started loading the windows but when it was about to form the windows flag (windows 7 loading) the pc was crushing and a blue screen with white words was appearing.
So i tried the following solutions according to things i heard and read with no effect:

- I upgraded the BIOS drivers for the motherboard.
- Replaced my new ram with another of the same model from the place i bought it ( beacuse they said me that the ram was faulty but the same problem appeared again ).
- I changed from 32-bit to 64-bit OS (Beacuse i read that a 32-bit OS can only run with a maximum of 3GB RAM. However i face the same problem).
- Lastly i gave my new RAM to a friend and it works great.

So i am trying to fix this problem for months now beacuse the guys at the shop want a big amount of money and i cannot afford this!
This thing has driven me mad and i would really appreciate it if someone could find a solution for me!

Thank you!

P.S. Sorry for that big explanation and any bad english expressions or words(I am 16 years old greek guy).

Make sure to configure your BIOS to operate both DIMM slots in single-channel mode.

EDIT:
Also you should make sure that the BIOS has both sticks set to run at the same clock frequency and latency.

load bios to factory defaults,or make a clear CMOS, also i dont recommend using to diferents brands of RAM, so using the Transcend DDR3 - 1333Mhz 4gb alone will be better,cause diferents brands,voltages,timmings ect.. tends to have this kind of issues on dual channel configurations.

well thank you but as i said i face problems even when i place the new ram alone so could the problem the clock frequency and latency?

Did you make a clear CMOS as I said to you ?( changing jumper besides battery to 2-3 position for a while without AC power conected to PC, then taking back to 1-2 normal position)

so you can enter bios setup to set RAM conf to manual mode ,so you can set 1333mhz speed , and timings (for instance 9.9.9.24, it depends on memory label ) manualy.
you used to have a 1066mhz speed ram, and now you want to use a 1333mhz, some times bios gets configurations issues when changing RAMs

Thank you for helpnig me... well i didnt have enough time today but i will try to find all these things tommorow. As for the speeds i changed from auto to 1066 and then to 1333 but nothing...i dont know if that was what u meant dor the speeds...tommorow i will search for the cmos clear. I am not that familiar with BIOS u see...i have started learning to use it since i have bought my new ram.
