Windows 7: Constant BSOD Errors. All The Time

If unsure about all the settings, or how to adjust them, the best bet would be the
"Reset to Opitmized Defaults" option in the bios.

I would still run Memtest as well, just to be sure theres no issues.

Thank you so much. I just wanted to get the system back to default in BIOS before I ran the Memtest. I'll try this now.

EDIT:
Ok, I went back into BIOS and set the DRAM Frequencies to set Automatically instead of Manual. So instead of running at like approx. 573Mhz, it's running at approx. 430Mhz and the timings are now back to 5-5-5-15 instead of 5-7-7-20

Hello,

Are you using Memtest86+ as recommended by CarlTR6 on Post #6?

When having issues it is best to return the BIOS to default settings.
Did you have the settings at default the first time you started the computer?

After you re-set the BIOS to default, what are the RAM timings (first four) and DRAM voltage settings?

You should D/L your motherboard manual, Asus M4N78 PRO here.
Read the section on your CPU and Memory.

From the website:
Quote:
Memory 4 x DIMM, Max. 16 GB, DDR2 1200(O.C.)/1066*/800/667 ECC,Non-ECC,Un-buffered Memory
Dual Channel memory architecture
*Due to AMD CPU limitation, DDR2 1066 is supported by AM2+/AM3 CPU for one DIMM per channel only. Refer to ASUSTeK Computer for the memory QVL (Qualified Vendors Lists).
From manual:
Quote:
This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less.
This will need to be checked.

Your RAM is on the recommended list, at 5-5-5-15 and 2.1v.

From your manual:
Quote:
Due to AM3/AM2+ CPU limitations, only one DDR2 1066 Dimm is supported per channel.
Quote:
Supports one pair of modules inserted into eithor the blue slots or the black slots as one pair of Dual-channel memory configuration
Confirm which slots your RAM is currently located.

Read the BIOS section in your manual, the CPU and RAM settings are in the AI Tweaker Menu section 2.4.

Let us know the:
CPU voltage
CPU/NB voltage
DRAM voltage

Can you D/L CPUZ?
Open CPUZ and take a screen shot of the CPU, Mainboard, Memory and SPD tabs, use the Snipping tool, Start button> All Programs> Accessories> Snipping Tool.
Save to a convenient place.

Then post using this method.

This will give us the basic info, in one easy to read post.

Posting from my iPod touch as I am running the Memtest reccomended by Carl.

The first time I booted the cpu, the BIOS was at default. We overclocked CPU and RAM afterwards. I am running 2x2GB sticks. One in the blue slot and one in the black slot. I did not default the entire BIOS before running the current memtest. Just turned the DRAM Frequencies back to Auto.

I have CPUz and will post back in the morning as the test on the first stick is currently on pass #4 and its 2:45am where Im at. Haha, Thank you!

Hopefully it will pass the memtest86+.

My guess is there will be a couple of settings that will need adjusted.
When you OC the CPU it will affect the FSB (Front Side Bus) which in turn affects the RAM.

Which slots are your RAM sticks in, DIMM A1 and DIMM A2, the numbering system is from your MOBO manual.

Let us know what the DRAM Frequency and NB Voltage is set at.

Ran the first Memtest on Stick 1. 15 Passes, No errors.

I also found out how to default my BIOS back to stock settings after the Memtest. But for your info, my CPU WAS at:

CPU Ratio: 15.50x
FSB Frequency: 215
PCIE Frequency: 100

CPU Voltage: 1.3875
CPU/NB Voltage: Auto
DRAM Voltage: 2.100V

Everything, as of now, is turned to Auto.

My RAM is inserted into DIMM_A1 & DIMM_A2.

I have attached the photos of CPUz. FYI, because I just finished Memtest, I have only ONE stick inserted into DIMM_A1

Good work, legend. I presume you are going to test the second stick now?

I have one question. I just want to confirm that you updated ASACPI.sys Thu Aug 12 22:52:52 2004 to a version dated 2009 or 2010?

If memtest86+ passes on the second RAM stick, and your still getting BSoDs then update your BIOS to Version 1205.

Ok, I know I did this step. ASACPI.sys in System32/Drivers IS stamped from 2009 now. However, I did a search for this system file in the System32 subfolder and stumbled across another ASACPI.sys file. But this one is located at System32/DriverStore/FileRepository/atk2000.inf_x86_neutral_b17c6a10719e3b19.

This ASACPI.sys file is stamped 2004. Also in this same folder is atk2000.cat (stamped 2004), atk2000.inf (stamped 2004), and atk2000.PNF (stamped 2010)

What are these and would this be any cause for error??


Yes, I'm getting ready to test the second stick. Quick question though. Stick 1 was tested in DIMM_A1. (its original position) I was thinking about testing Stick 2 in DIMM_A2. (its original position) If Stick 2 comes back with no errors, can we effectively say that both sticks AND both slots are not faulty? Therefore removing the need to test Stick 1 in A2 and Stick 2 in A1. And would I need to check slots B1 and B2 even though I don't use those?
