BSOD randomly (playing games/idling/downloading) error 0x0000001a

Hey Guys,

So I am experiencing BSOD at random times. This is frustrating because I am pretty sure I eliminated all the possible reasons for my computer to Blue Screen. I changed my motherboard, I scanned my hard drive, got all the drivers for my video cards, etc. I also checked my ram one by one.

Now here is what info I got on my crash dump files

On Sat 19/01/2013 6:32:11 PM GMT your computer crashed
crash dump file: C:\Windows\Minidump\011913-46285-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x7EFC0)

This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

Also when it Blue Screens I was able to get a copy of what the Technical information that caused the blue screen.
