The RAM frequency settings look good.

Can you check your BIOS for the voltage settings?

Have you been checking your temperatures?

Use Real Temp to check the CPU temps when at idle, under load and/or testing.
Let us know the minimum and maximum temps you get.

Go to your BIOS and tell us what the CPU, RAM and the CPU integrated memory controller voltages are.

Have you overclocked the CPU?
Or is that a turbo mode setting?

You're getting a lot of event errors from Spybot, try installing an up-dated version or un-install it and use Malwarebytes.

Looks like no overclocking, is this correct?
Have you ever OC'ed this rig?

Those idle temps seem a little high for a stock CPU cooler, but within range. You might want to consider getting an after market CPU cooler, they are good ones in the $25-50 range. You can consider this after the crash source is found.

First run memtest86+, with all RAM cards installed and at current voltages and settings. If you get any errors, stop the test and report here. Best to run the test over night, just watch it for a couple of hours for errors.

When you run memtest86+ you are looking for bad RAM cards, bad motherboard slots, so you need to follow the testing procedure in the tutorial.
Sometimes errors from these tests can be corrected by adjusting the settings.
RAM - Test with Memtest86+

Is there a specific reason you lowered the RAM voltage from 1.65v to 1.50v?
Did you have any crashes before lowering the voltage?

If you want to lower the DRAM (DIMM) voltage you need to lower the DRAM frequency first.
The CPUZ SPD tab is the Corsair list of recommended timings, frequencies and voltages. Use this to set the RAM timings.

If you want to run the RAM at 1600MHz, then put the DIMM Voltage back to 1.65v.

With more than 4GB RAM I would bump the CPU VTT voltage, that's the CPU integrated memory controller.
Bump the CPU VTT voltage to 1.25v, but only with DIMM Voltage of 1.65v at 1600MHz.

Run memtest86+ again.

Ok so I just did a fresh windows install with SP1 a week ago and all the windows updates are done. The same day I got the BSOD again. This is still happening at least once a day.
With this fresh windows install i don't have spy bot installed ATM.

About the missing windows drivers, where do I check or what should I give you to see if they are still missing?

I have not OC'd my PC, it's running stock at 2.8 GHz.

As for my system temperature, I did buy and currently is installed this Heatsink & Fan - COOLER MASTER Hyper N 520 RR-920-N520-GP 92mm Sleeve CPU Cooler Intel Core i7 compatible
Also, on my Mobo, there's a temp and it usually reads between 25 - 29.

So I just finished running Memtest and last night when i tried running it using V4.0 it wouldn't start so i ran option 2 which is the previous version and this did work. It ran for 9 hours and did 10 passes with 0 errors.

I had lowered the RAM voltage just to try and see if that was the cause because the Intel guy had told me they're CPU's only run RAM at 1.5 V but it still crashed. I ran the memtest at 1.65V.

I have yet to increase the CPU VTT voltage and I will try that now.

I just set my CPU VTT Voltage to +0.75mV and the status shows 1.25V. It actually varies from 1.24V to 1.27V but mostly steady on 1.25V.

Good that memtest86+ passed, we will have to run it again later, it takes running it a few times to be sure the RAM is stable.

Is your RAM frequency still at 1600 (800MHz)?

With the CPU VTT Voltage set to 1.25v, and RAM voltage at 1.65v, run the Prime95 torture test for two hours. This will max out your CPU and test memory, be sure to watch the CPU core temps closely when it starts up, they should level off in a couple of minutes.

CPU - Stress Test with Prime95
Prime95 Torture test
If memtest86+ passes then run Prime95 torture test.
First open Real Temp to monitor CPU temperatures, don't go over 73C.
Open Prime95 and stop the test if it is running, in Advanced tab select 'Round off checking', in the Options tab select 'Torture Test...', in the window that opens select 'Blend', after 'Number of torture test threads to run' enter 8, then click OK to start the test.

Your previous CPU core temps are high for an aftermarket cooler, should be lower 30's.
Did you install it?
Is there any thermal paste built up around the edges of the CPU and heatsink interface?

Post the complete dump files if you have another BSoD.

So it's been a month since i set my CPU VTT Voltage to 1.25v and ever since then my windows never crashed. Thank you so much. I think this resolved the problem.

You're welcome.

Thanks for the update. Glad to hear it's running stable.
