Code:
BugCheck 1A, {41790, fffffa800615d7a0, ffff, 0}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+35054 )
Code:
Usual causes:  Device driver, memory, kernel
Remove:

Code:
Start Menu\Programs\ASUS\AI Suite II
Start Menu\Programs\ASUS
These are usually bloatware, which can slow down and corrupt your system.

What AV program are you using? I couldn't see any installed, here are some recommendations, due to stability and low resource consumption:

Install and perform full scans with: Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system.

You can also view this thread for a complete free and lightweight security protection combination:Memory:Run Memtest86+ for least 9-10 passes, and preferably overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Test each RAM stick and every motherboard DIMM slot available.

I did the memtest and when I use all 4 sticks it passed two times, failed once, and then 3 times failed with a ton of errors, finally freezing on test 8. With single sticks passed a couple of tests, and putting two in each slot seperately passed. Why would there be an issue with memtest only when all 4 sticks are in?

When you started testing separately, did they fail within a particular slot?

Post a screenshot of each window from CPU-z, and including the SPD tab for each DIMM slot:

Did not fail one at a time in any slot. No failings whatsoever. Only fail was with 4 sticks in.

Are you using different RAM modules? They seem to be running at different clock speeds too, which may cause some problems.

RAM modules are usually installed in certain slots, and in matched sets or pairs.

If you are overclocking, go to bios and set everything to optimized defaults. In the SPD tab, it shows 1 dimm slot at a time. can we see all 4 SPD tabs please. Did you buy this ram as a set or are they different modules? When you set your bios to defaults, put the tweaking section to manual, manually set the timings on the ram sticks and manually set the dram voltage. Set the boot order, sata mode and save and exit.

You will have to let each stick run 7 full passes in each slot. It will take some time but should point which stick is bad.

The sticks are a set 4x4gb corsair vengeance. Sorry didn't realize there was a different page for each slot. Including that corrected. Am a noob at this to be sure. Nothing should be overclocked unless it does it standard on the board. Unfortunetally I am a noob at bios as wel. Going to look into setting it all manually.
