I have a computer with a Memory of 2GB DDR3, and my Dad bought a 4GB DDR3 Module but it is half of its size. Let's call the computer with 2gb ddr3 memory as "myPc" and the 4gb ddr3 as "DadPc". I want to replace my old memory from myPc to a new 4gb ddr3 memory that it is inserted on my dadPc. I want to swap them. But the problem is when i insert the 4gb module to myPc, it will only load until on the boot screen, and it will restart again. It keeps on restarting. But when i inserted the old 2gb on my DadPc. It works fine. Until then when I inserted it back to their own slot, myPc gets a Blue screen Physical Dump memory.
Here's myPc specs:
Processor: Intel Core i3-540
Mainboard: Intel DH55TC
Video Card: AMD Radeon HD7750 1GB DDR5
MEMORY: 2GB DDR3.
I provided some screenshots of my detailed specs (using CPU-Z)
