I would firstly run Advanced System Care from iobit.com and clean your registry, defrag your hard drive and check you have the latest video driver installed with all of the windows updates.

If it has the blue screen error, try to turn off the pc, remove the power cable and battery. Press and hold the power button for 5 seconds. Reseat the cables and battery. turn on the laptop.

If Blue screen occurs, turn off the pc and reseat the Hard Drive. If it still occur, then that is the time to replace the hard Drive..

A blue screen came up saying something about the memory module!


oh k..
so u mean whenever u start ur computer or whenever u work on it, it shows Blue screen...
This blue screen is called BSOD Error (Blue Screen Of Death)
It occurs due to several reasons but since u specified abt memory, this might be showing you Kernal Memory Dump, i hope..
Dont need to panic, try to start up computer in safe mode & restore it to previous known date at which u didn't had that problem..
It generally occurs after installing some new softwares or drivers that conflicts with the memory module.. so try to restore ur system else try removing ur newly installed software or driver...
Hope this helped u out..
Thanks....
