The Windows 7 0xc0000005 error is an error code that takes some effort to pin down. Obviously you have tried searching around and tried to come up with what the issue could be. A lot of places will reference memory scanners to check the physical RAM on the computer.
That really isn’t a bad idea. You can download plenty of free applications to check it out, such as MEMTEST86+ to run a full physical scan on all sectors of the memory. Any bad bits will come back and you will know to replace your memory or have it serviced by the manufacture. Once you rule out physical hardware issues, you now have a solid basis to proceed with troubleshooting.
The next step is to check for spy-ware and mal-ware that might have gotten on the machine. There are plenty of free anti-malware and anti-spyware applications available on the internet for download. I would recommend downloading something like Spybot Search and Destroy from Safer Networking. You should be running this periodically anyways since spyware is so prevalent it is almost impossible to avoid it all together.
Install Spybot and perform a full scan. It will take a while to complete, but it scans everything from files to the registry keys. Once the scan finally completes follow the instructions to clean out anything it finds, most particularly registry key issues. After that follow the instructions to immunize the computer which prevents a lot of these sort of issues in the first place. Quite possibly even the Windows 7 0xc0000005 error.
Now that you have gotten any potential spyware cleaned off of the machine, it is time to perform a deep scan of the registry. The registry is another place that it is important to periodically clean and remove invalid or corrupt information. Download and install a registry cleaning application. Applications such as RegGenie will find and remove those invalid or corrupt information. Once you have finished this additional scan follow the instructions to clean up the registry information it finds, which hopefully should clean up your Windows 7 0xc0000005 error.
