Windows 7 Memory_Management BSOD and random hang ups

[Hipposly]

I have an Acer X1700 PC 4gb Ram Intel Pentium Dual CPU E222o @2.40ghz
I've been experiencing BSODs and hang ups. I just swapped out the video card thought that was the problem
But i guess not. I installed the Radeon HD 5450 I've attached a copy of the dmp file Thanks fpr looking

A Hardware fault is the cause, seems to be defective RAM

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: 82e4bc23, The address that the exception occurred at
Arg3: 807866dc, Trap Frame
Arg4: 00000000
