Windows 7: BSOD about 3-4 times a week. Not specific to any particular action

BSOD about 3-4 times a week. Not specific to any particular action

As mentioned the crash isn't specific to anything I'm doing. It just happens sometimes. I've even tried forcing it by using the driver verifier and running as many online videos/games as possible and couldn't get it to happen. Sometimes I'm literally just reading a document and it crashes. I should also mention that the computer is new and was put together by a buddy of mine so its possible he messed something up. I didn't think far enough ahead to copy down the error codes (I thought the memory dumps would be enough) but the next time it crashes I'll be sure to post them. Thank you guys for your time

Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc).  If a kernel debugger is
available get the stack trace.
Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.
The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
*Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
*If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
*If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
*If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
*If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

Errors are sometimes found after 8 passes.

Do this test overnight, before going to bed.

So I cracked open the tower to get a look at the RAM and they are in the recommended slots, however, the brand of RAM (patriot) is not on my motherboard's (ASUS P8 Z77-V LK) qualified vendors list. The size, timing, and voltage of my RAM exactly matches some of the other RAM sticks on the list though. Could this be the cause of the BSOD? I'm going to begin running the Memtest so hopefully that will tell me something also. Thanks again

It depends on the details of the RAM, Asus can't test all the RAM available for each board.
Run memtest86+ for 7 full passes, with all RAM cards installed.
Best to run overnight as depending on the amount of RAM you have may take several hours.
If you get any errors you can stop the test.

With more information, we can make some recommendations.
Can you download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.
For posting the information , enter 'Snipping tool' in the Start button > Search box, hit enter. Select the area you want to post and save to a convenient place.
How to Post a Screenshot in Seven Forums
Go to your BIOS and tell us what the CPU, RAM and the CPU integrated memory controller voltages are.

It will help if we know what components you have.
Can you fill in your system specs?
You can use this app to find them: Speccy Free System information Utility
Then enter them in the 'My System Specs' drop box at the lower left of any of your posts.

All the requested info

I ran memtest for about nine hours and it ran 9 passes, none of which turned up an error so I guess my RAM is good. I uploaded all the requested information from CPUZ. I wasn't exactly sure what you meant by "memory controller voltages" so I also uploaded two pictures from my bios. I hope those have what you're looking for. I've also updated my system specs. Thanks again guys.

Good work, better for us to know what components you have.

The CPUZ SPD tab gives vital info, there is a drop box in the upper left corner, you can select different 'Slots', post snips of the populated slots.

Download your Motherboard manual: Asus P8Z77-V LK
CPU voltage, pg 3-11
DRAM voltage, pg 3-12
VCCSA is the memory controller voltage, pg 3-12
They are in the AI Tweaker Menu.
If you can't see a voltage number, select 'Manual', if you still can't see a voltage number then increase it by the smallest amount. Post the settings here.

Sorry about that. It was awfully dumb of me to post a snip of nothing. I have posted snips of the active slots now (2 & 4) which are the blue ones on the motherboard. I feel like I should also mention that in the two months I've had this computer it has completely just shut down twice (no BSOD) due to the CPU fan functioning improperly. Upon restart the BIOS menu would pop up and ask me to restart the fan. After restarting the fan everything would be fine again. This happened a few days after I got the computer and just yesterday. Not sure if this will help diagnose the problem or if its even relevant. Here's the voltages you asked for:

CPU 1.024V
Dram 1.5V
VCCSA 0.925V

Thanks again

Have you had any crashes since your first post?
Always post the full crash reports for any crash you have.

When the CPU fan stops the system will shutdown to prevent damaging the CPU, an abrupt shutdown can cause many different kinds of BSoDs.
How are you 'Re-starting the fan'?
Do you have the stock Intel CPU cooler?
Make sure the CPU fan is firmly connected, with the system off, power disconnected, remove the CPU fan plug, look for bent pins or anything unusual. Re-connect CPU fan plug and re-start.

The CPUZ SPD tabs and voltages look ok, for now. Just because your system passed memtest86+ doesn't mean the RAM isn't causing issues. It's the same with all hardware testing.
We may need to come back to this.

I have had one crash since my first post. Unfortunately, I have also ran CCleaner since then and it deleted the memory dump files. If there are any more crashes I will be sure to post the memory dump files. So when the fan stops working and the computer cuts off (which has only happened twice since October) a dialog box pops up in BIOS asking me if I would like to restart the fan. I simply click yes and then everything is fine again. I have checked the CPU fan plug and everything seems perfectly fine; nothing is bent or corroded. If it's at all helpful I have posted a pic of the back of the fan with all it's info on it. I intend to run memtest again tonight before going to bed.
