I've just upgrade my ASUS K53SJ to 8Gb of RAM (the original is 4Gb), I'm using 2x Elpida 4Gb 1333Mhz.
When I use just single one of RAM, everything works fine, but when I combine and use both of my RAMs, my computer usually freeze like this pic below

And for sure, I can't use it any more, I need to hold the power button to shut it down.
I'm using Windows 8.1 with lastest update, running on Intel SSD 530 120Gb.
Please any1, do you have any idea what happens with my laptop? :(
Thanks in advance and sorry for my English.
UPDATE 1:
Processor: Intel® Core™ i5 2410M
Chipset: Intel® HM65 Express Chipset
Graphic: NVIDIA® GeForce® GT 520M with 1GB DDR3 VRAM
Storage: Intel SSD 530 120Gb + WD 500Gb
Bios: last version
UPDATE 2
I did try to get another DDR3 8Gb instead of 2x4Gb, and seems like everything is running ok until now, so I will close my question here.
The problem may come from the voltage, my new Samsung DDR3L 8Gb (1.35v) seems working perfect with my laptop, it is running very smooth and no conflict.
Thanks.
