Multiple BSOD errors during randoms points in the day, 0x00000003d

Welcome to SevenForums.

* Does the computer BSOD in safe mode?
* Why are you having ATI Catalyst Control Center with a NVIDIA card?
* Any recent hardware or software changes?
* Are you overclocking any hardware?

* We do not recommend automatic driver updating software.
Find drivers:

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
- - The most common drivers are listed on this page: Driver Reference
- - Driver manufacturer links are on this page: Drivers and Downloads

McAfee is a frequent cause of BSOD-s, consider uninstalling it with the McAfee Removal Tool and replace with Microsoft Security Essentials (To test)

• How to uninstall or reinstall supported McAfee products using the Consumer Products Removal tool (MCPR)
  
  • McAfee Removal Tool - McAfee Uninstaller
  
  

Microsoft Security Essentials.

Recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software. It is free and lightweight:-

• Microsoft Security Essentials - Free Antivirus for Windows
  
  • Malwarebytes - Free
    
    • Good and Free system security combination.
    
    
  
  

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.

Upload a screenshot of your hard disk using CrystalDiskInfo:

Make a hard drive test from the hard drive manufacturers website:

• Hard Drive Diagnostic Procedure

Run Disk Check on your hard disk for file system errors and bad sectors on it:

• Disk Check

Perform a System File Check:

• Click on the
• Type CMD on Search
• Left click and Run as Administrator
• Type SFC /scannow

Full tutorial here:

• SFC /SCANNOW Command - System File Checker

Reduce items at start-up. Nothing except anti-virus is required:

• Startup Programs - Change
• Troubleshoot Application Conflicts by Performing a Clean Startup

* Report if this brings stability?.


If not, proceed with testing RAM.


Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

• RAM - Test with Memtest86+

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.

Let us know the results.

Check if CCleaner or Revo Uninstaller is able to find anything related to ATI:

• CCleaner - PC Optimization and Cleaning - Free Download
• Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

I would recommend using MSE during the time of troubleshooting. You can install your old antivirus after we've finished.

Look forward to your results.

Edit: For ATI, you could use Driver Fusion also. Delete remnants of its drivers/older drivers using Driver Fusion/Sweeper

Any BSOD-s so far?
Did you try the rest of it?

Did you follow the other steps provided on my first post?
How many sticks of RAM do you have?
You need to test each individually.

Have you checked for broken CPU pins? Checked if the other parts of your computer, like fans, power supply etc. functioning correctly?

Checked for overheating issues?

For monitoring the heat/celsius of the system, use Speccy or HWinfo:

• Speccy - System Information - Free Download
• CPUID - System & hardware benchmark, monitoring, reporting

Is the system free of dust and debris?
