5. As for your ram, have you some other modules? (by lending from a neighbor or friend - & which are compatible with your motherboard of course)

Keep us posted

Thanks for the detailed reply.

I'm on the first stages of debugging and you get the award for being the most co-operative OP so far! Haha, :)

Coming back to the BSODS

• Follow this tutorial for a different method to run the system file checker. SFC /SCANNOW : Run in Command Prompt at Boot

Are you sure you're video drivers are up to date? From my analysis I found (See the text in red):

Code:

Image path: \SystemRoot\system32\DRIVERS\nvlddmkm.sys     Image name: nvlddmkm.sys     Timestamp:        Sat Oct 15 12:07:55 2011 (4E99233B)

15.Oct.2011 So, they do require updating to the latest.

Take you're time and do the above and keep us posted.

Do all in the quote below and post back

Run some hardware checks.

• If you are overclocking any hardware, please stop.
• Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log (you may need to search for wininit instead of chkdsk).
  For any drives that do not give the message:
  Windows has checked the file system and found no problems
  run disk check again as above. In other words, if it says:
  Windows has made corrections to the file system
  after running the disk check, run the disk check again.
• Run the short and long tests with SeaTools for HDDs.
  SeaTools for Windows
  
  SeaTools for DOS
• Monitor temperatures during the following tests.
  Use the following programs to monitor the temperatures.
  • Real Temp is a good CPU temperature monitor.
  • Speccy - System Information - Free Download will monitor all hardware temperatures.
  • HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools can be inaccurate for CPU temperatures, but is a good program for GPU temperature monitoring.
  
  
  
  

  • Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Let it run until the GPU temperatures even out or until the GPU temperatures reach a dangerous level (you can find the max temperature for your card on either the nVidia or AMD sites; if you are not sure, ask us). The goal is to get a steady temperature, find out if the GPU is overheating, or to see if there are any artifacts present in the test itself: look for strange pixelated patterns on the screen or colors that do not look like they belong. Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory. Let the memory test run for at least seven passes; the more the better.
  • Run Hardware - Stress Test With Prime95 to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.
  • Follow the steps for doing CPU stress test using IntelBurnTest

Good information and trouble shooting so far.

I am not overclocking any of my hardware.

Tried to run chkdsk and as it was going through it BSODed. Rebooted in safe mode and attempted to run chkdsk in there. BSODed again. Neither time did it come anywhere close to finishing the test.

When I went to boot my computer to run Seatools (I’ve been using my laptop to access the internet and post and only turning my computer on to run the tests since it tends to BSOD after sitting there and hour and I don’t want to damage it) it froze after the windows logo came up but before the blue logon screen. I had to do a hard restart. After that it logged on fine but I shut it down normally.

I have used several of those stress tests in the past and never had problems with overheating or crashing. I’ve used furmark before and usually have Coretemp running in the background, which monitors CPU temp. My CPU temp holds steady at 28-31 C at idle. Overheating hasn’t been a problem ever in the past for me, though I realize something could have broken in the interim.

Good steps, always a good idea to start eliminating the hardware.

Sorry for not following directions entirely but I was following my earlier hunch and removed my two extra memory modules. After doing this my system has become more stable. Since doing this I have been able to run the tests you told me too w/out getting BSODs.

Since you have four RAM slots and 12GB RAM, did you buy them at the same time?
Same brand and frequency and timings?
Did you leave the 2x2GB cards or the 2x4GB cards installed?

This can sometimes be fixed by adjusting the RAM settings.
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.

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

I went back to the SFC scan you told me to run and ran it from within windows (I made a repair disc and tried to do it from boot but when I get to the part to select which operating system to fix it doesn’t show my install. I know you can load drivers for your HDD so I checked online to find ones for my HDD and none exist. So since I can’t see it in the boot version I just tried to do it within windows. Maybe this is caused by having a dualboot?). Running The SFC scan w/in windows it did say it found corrupt files and was unable to fix some of them. So I ran it again as the tutorial instructed. Same thing, some corrupt files unable to fix. I ran it 2 more times with the same results. I’ve attached the log from the scans.

The last thing I did was run chkdsk as instructed. Chkdsk completed without any issues or crashes. It told me it the drive was clean. While it was running it didn’t report any damaged sectors or files.
Again I’m sorry for not following directions. I was just worried that all the BSODs would damage my computer and doing the tests always resulted in a crash so I thought to avoid that I’d try this. My initial tests in memtest 86+ showed all my memory was good but I tested them all in the same slot. Which means that if the memories all fine then it might be one of the dimm slots on my mobo.

The problem may be caused if the repair disk was made from a non SP1 version of Windows 7.
What is your other dual boot OS?
Do you have a OS image backup?

Frost65 said:

I further tested this by redoing the the memtest86+ and the RAM checks out. I haven’t had any issues since pulling the memory out of the extra dimm slots and even have swapped some memory with it and it’s been stable.

Always test RAM in different slots.
Did you run memtest86+ with all four RAM cards installed?
How many passes did you let memtest86+ run for on the previous tests?

Do you still only have two RAM cards installed?

Post the CPUZ and BIOS setting info requested and we can adjust the settings to see if that will help.

Your last crash:

Code:

STOP 0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUAL
Usual causes:  Device driver
*** WARNING: Unable to verify timestamp for nvlddmkm.sys
IMAGE_NAME:  nvlddmkm.sys

This may be caused by the RAM issue.
You may want to uninstall your Nvidia driver, run Driver Sweeper, then install a new version.

Your System Event Logs stopped in July, so no current useful info there.
Same for the App Event Logs which stopped in September.

Code:

Unloaded modules:
fffff880`0a5d2000 fffff880`0a5d8000   RTCore64.sys

This driver is known to cause crashes in Windows 7.
If you have any ECS utilities installed, un-install them for testing purposes.
Also, RivaTuner or MSI Afterburner.

What version of Acronis or Seagate DiscWizard are you using?
If you're using Seagate DiscWizard They have a new version available (V.14387).

Since you have four RAM slots and 12GB RAM, did you buy them at the same time?
Same brand and frequency and timings?
Did you leave the 2x2GB cards or the 2x4GB cards installed?

I did not buy them at the same time but they are the same brand and frequency timings.
I currently have the 2X4GB cards installed.
Here are the screens:

Attachment 230723


The BIOS reported my CPU vcore at 1.056v and my vdimm at 1.500v Those were the only ones I could find.

The problem may be caused if the repair disk was made from a non SP1 version of Windows 7.
What is your other dual boot OS?
Do you have a OS image backup?

My other OS is Win XP professional x32 SP3.
I don't think I have an OS image backup. I have some image backups of xp. But none of my win 7 install.

Always test RAM in different slots.

I ran memtest86+ with all four RAM cards two weeks ago when the issue appeared and it came up with errors. However, when I then tested each one individually they checked out.

There’s a weird thing about my mobo that doesn’t really allow me to test RAM in each of the slots individually. It’s been like that since I bought it. Basically it won’t boot with just one stick in slot 1 or 3. It will boot with a pair in just one and three but for some reason it won’t allow my gpu to work so you can’t see anything on the screen. Everything works and the gpu’s fan turns on and everything, but the screen’s just black. The primary slots on my board are 2 and 4. So when I tested individually I tested them all in slot 2.

As for passes I only did one pass on each stick.

I still only have two RAM cards installed. 2X4GB in slots 2 and 4.

You may want to uninstall your Nvidia driver, run Driver Sweeper, then install a new version.

Okay uninstalled the driver. Ran the sweeper. Reinstalled w/ a fresh download from the nvidia site.

This driver is known to cause crashes in Windows 7.
If you have any ECS utilities installed, un-install them for testing purposes.
Also, RivaTuner or MSI Afterburner.

I know I don’t have RivaTuner or MSI Afterburner installed. I don’t think I have any ECS utilities installed but if I do I don’t know what or where they are. Can I just remove the driver via driver sweeper?

Looks like you may be having issues with Norton Anti-Virus, we can look at that later.

Okay. Just let me know.

This driver is out of date and should be removed.
What version of Acronis or Seagate DiscWizard are you using?
If you're using Seagate DiscWizard They have a new version available (V.14387).

Okay. Uninstalled DiscWizard from the add/remove programs list. Installed the latest version.

Thanks for all the help so far I really appreciate it.

Your welcome.
Good feedback, it helps.

The most important issue is the SFC scan failure.
The report shows a lot of failures, many processor related.
The fastest way to fix this is to try a System Restore to a point before the crashes started.
How to Do a System Restore in Windows 7

If that doesn't work or you don't have the right restore point then you need to re-install Windows 7.
I recommend a clean install but you can do a repair install.
How to Do a Clean Installation with Windows 7
How to Do a Repair Install to Fix Windows 7
A Repair Install can take up to 6-10 hours or more depending on how many programs you have, just let it run.

If/when doing the Repair or Clean install, have only 2 RAM cards installed in slots 2 and 4.

When your system is stable make an Image Backup with DiscWizard, this makes fixing issues like this very easy.

Depending on which way you decide to go, uninstall or update these programs.

• Uninstall Norton Security Suite, use MSE at least until your system is stable.
  Microsoft Security Essentials*
  
• Uninstall CPUZ and install the latest 1.61 version. The above snips are showing errors in some readings.

Do not use the CD that came with the motherboard, D/L all drivers from the motherboard support site.

FYI, memtest86+ needs to run a minimum of 7 full passes, best to run overnight.
If you get any errors you can stop the test.
When memtest86+ gives errors with all RAM cards installed and passes with individual cards it usually means the settings need adjusted. This can happen after the system has been running stable for years, it's usually due to component wear.

Let us know if you have any questions.
