Here is the current detail of my Notebook memory by CPU-Z

And I tried to replace one of the 1Gb module with 4gb Corsair value select model no (CMO4GX3M1A1333C9).

But the laptop wont start beyond bios logo and if I do start up repair the blue screen error comes.
I have tried every combination like using different slots for new ram or using only new ram.

Does the laptop support 4GB sticks, is this a supported stick....laptops are very picky about the DRAM they take and aren't like a desktop where you can adjust timings and voltages....the stick is prob good but isn't compatible
