Hi I have got a ASUS K52JC laptop that is with 4GB of RAM (2x2GB) and I wanted to upgrade it to 8GB which is the max of the laptop can handle. I have check the same DDR3 1333 and 1.5v RAM and then after I insert the RAM the laptop will takes me to ASUS log and then starting windows then it randomly restarts over and over can't get into system. I went to the BIOS setting and I can see the RAM is 8GB but just can't boot the system. Please help thank you.
