    Hi,
    Use the old RAM modules, download and install CPU-z, run it and post the Memory tab and SPD tab pictures.

    Hi,
    You need to upgrade with a PC3-10700 1333MHz module, you are trying to install a incompatible RAM, PC3L RAM has 1.35v, you have to use a 1.5V RAM like PC3-10700 module.
    Example:
    Kingston Technology KVR13S9S8/4 4 GB 1333 MHz DDR3 Non-ECC CL9 204-Pin SO-DIMM Value RAM Memory, 1.5 V: Amazon.co.uk: Computers & Accessories

    I see. And is it possible to install 8 gb ram with 1333 mhz? Attached is the picture of it. Thank you so much

    Thanks. I just bought 4gb ram (3 pictures in attachment), tried to add it to already existing 2gb old one into another slot, but it still does not enter windows. Restarting endlessly.

    This is the specification of the 4gb ram i bought. Please see in attachment. Its just 10600 instead of 10700. Should it be the issue?

    Hi,
    Try the module in different slot, I am running out of ideas, 10600 same as 10700, as long as the speed(1333MHz) matches with the original RAM it will work, I would suggest you take it to a local laptop repair shop and let a technician have a look.
  • Does the bios recognize the 4gb of ram in the INFORMATION tab?

    Yes it does. It just wont enter windows, at the moment when windows is loading (glowing colors moving around "windows"), there come the blue screen, sometimes it just flashes blue screen and restarts in the end.

    What happens when you reinstall windows?
    I did not even try to. I've read on some forums that reinstalling windows has nothing to do with it. In fact, windows works fine on old module, on both ram module slots.
  • You bought a ddr3L memory:

    Your model uses ddr3:
