記憶體造成當機? w7 x64

下列是藍白當機畫面 幾乎一個禮拜當機一次
A problem has been detected and Windows has been shut down to prevent damage
to your computer.

The problem seems to be caused by the following file: ntoskrnl.exe

MEMORY_MANAGEMENT

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

Technical Information:

請問這個換記憶體會改善嗎? 還是是軟體問題?
配備如下
