Windows 7 blue screen memory error bugcheck 0x0000001a

Here is my system specifications.

Error:

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001a (0x0000000000041790, 0xfffffa8003d23de0, 0x000000000000ffff, 0x0000000000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 080515-65988-01.

bugcheck 0x0000001a means MEMORY_MANAGEMENT. The important information come from the parameter 1.

0x41790 means this:

A page table page has been corrupted. On a 64 bit version of Windows, parameter 2 contains the address of the PFN for the corrupted page table page. On a 32 bit version of Windows, parameter 2 contains a pointer to the number of used PTEs, and parameter 3 contains the number of used PTEs.

According to Microsoft, this is mostly caused by RAM (Hardware) issues:

The 41790 code is part of our an internal memory manager code but the bugcheck in my experience has almost always indicated hardware issues (RAM errors).

So, run a memory test tool (memtest86+ or the internal Windows tool). Also check the RAM timings with CPU-Z and look that the values from the SPD tab match to the data in the memory tab. If you have a command rate (CR) of 1, go to the BIOS and set it to 2. This can also trigger such BSODs.
