BSOD help

I have only gotten through two sticks on all slots. I have two more to go through. So far the two I have tested have come back with no error after at least 12 passes on each of the four slots on the board. Sorry about not posting it directly in there. Where can I find the DRAM and CPU/NB voltages then? I don't know how to update the BIOS. I tried downloaded the BIOS update utility, but when trying to install it, I received an error that my OS is not supported, so I checked for a 64 bit version (same originally downloaded) and got the same error. All I know about the ram is that it is at 7-7-7, but on the sticks the label says 8-8-8 @ 1.65 V i think, but I don't know what they are currently being run at. Once I finish memtest on all the sticks, I'll let you know the final results. It will probably be Monday evening or Tuesday.

I don't know if this helps any, but Memtest shows me this information:
Processor @ 3211 MHz
RAM settings 533 MHz (DDR1067) / CAS : 7-7-7-16 / DDR3 (64 bits)

Did you DownLoad your motherboard manual that I linked in the previous post?
If not then go ahead and D/L it.
Read about Asus EZ Flash 2, page 3-5.
How to use your BIOS starting on page 3-7.
DRAM and CPU/NB voltages on page 3-12, 3-16 and 3-17.
Read these pages and get familiar with your BIOS and where to find things.
Read this post about updating Asus BIOS. Use a USB memory stick.
EZ Flash 2 – the best, the safest and the most convenient way to update BIOS.

OK. I must have missed that part of the post. Sorry. I'll do that after I finish running the Memtest.

If any of the memtest86+ start showing errors you can stop the test, mark down the RAM card and mobo slot the errors occurred in.
Test a known good RAM card in the same slot that failed, this will confirm if the RAM card is bad or the mobo slot.
Then continue with the next test.

I finished doing the memtest86+ and received no errors. Each test was at least 12 passes on the individual sticks in each of the slots. So i guess it isn't a memory error... 
When updating the BIOS, should I just start with the first update and do each relevant one, or all, until I reach the latest one, or what? I've never had to update a BIOS before.

Have you ran memtest86+ with all four RAM cards installed?
Stop the test if you get any errors.
Did you find the DRAM and CPU/NB voltages?
The next step is to check the voltages from the BIOS and make adjustments depending on what the voltages are now.
Updating (flashing) the BIOS can cause your motherboard to lockup and become un-usable if not done correctly, since you have had problems before, I would recommend to try and get some help doing this. Friends or a local shop would be the place to start.
Let's do the voltage checks first.

Yes, I completed the memtest86+ with each card individually in all slots, like I was advised and no errors came up. I did at least 12 passes on each stick in each slot. I did not know you wanted me to run all four sticks together again. I will do that tonight.
I have not found the DRAM and CPU/NB voltages, because everything in the BIOS is set to auto, so I don't know what they are at.
I have done a BIOS flash before, but it was a different mobo that had a utility that ran within windows. I know how to do the EZflash, now that I know I have it. I didn't realize I had that feature, but I have never encountered the issue of more than one BIOS update. So I need to know if I install all of them sequentially, or if I just do relevant ones until i reach the latest, or what?
By the way, I have not had any problems within the past few days, and I have been performing the same tasks as I did when I would receive the errors before. I noticed that my RAM in slot 2 was not seating as easily as the others so I made sure both sides locked in when I put the RAM back in.

First, by testing the RAM cards in different motherboard RAM slots you can check if all the RAM cards are good and if any of the motherboard slots are bad.
If everything passes then it's likely that a DRAM or memory controller voltage bump will help. Testing with all the RAM cards installed will confirm this, if it passes then re-seating the RAM cards may have corrected the problem or it might be borderline voltage settings on the DRAM or memory controller. If it doesn't pass then the voltage settings need to be adjusted.
The goal is to get the system stable with the least amount of voltage, voltage causes heat and high voltage will possibly cause damage to the RAM and too much heat.
To get the DRAM and CPU/NB voltages select it in BIOS increase by the smallest value possible, this should then give you a voltage number.
Let us know what they are and we'll proceed from there.
If you feel comfortable updating the BIOS then install version 3406.
If the RAM wasn't seated correctly this could be the cause of the problem, if it has been stable then try to stress it with something you normally do or run Prime95 torture test - Blend, this will test your CPU and the RAM, if it runs for an hour with no errors or crashes then your system is probably stable. If it passes and your comfortable with it, then use normally and if you get another crash you can post back here.
CPU - Stress Test with Prime95
Click 'Round Off Checking' as in the first post after the tutorial.
Options > Torture Test > Blend > select max number of threads for your CPU.
Watch the temperatures closely for the first 10 minutes or until the temps stabilize. If your not sure of your CPU max temp limit then don't go past 70 deg C.
Use Core Temp for monitoring CPU Core temps.
Let us know how everything turns out.

After 12 passes, 24 hours of testing, on memtest86+ with all RAM installed, no errors were detected. The voltages are: .8 for the CPU/NB, 1.5 for DRAM. So far the system has been running stable. I'll let update this post with my Prime95 results.
Edit: I ran Prime 95 and no problems, everything passed. It must have just been a bad seating of the RAM. And by the way, during the test, my temps never got over 49C.
