Occasionally getting BSODs

[Snuck]

Hi,

I am using Windows 7 Ultimate x86 on a PC brought about 2 months ago (Intel Pentium Dual Core E5300 @ 2.6 GHZ, 3 GB RAM and a NVIDIA G100 graphics card) and I've been having for some time now these frequent BSODs that are kind of annoying me because I can't seem to find the exact solution for my problem. This is how it was behaving at first: basically once in a while, after pushing the exit button on some random games I was getting this error. But yesterday I got a BSOD while just exploring some folders and no game exiting was involved whatsoever so then I started worrying quite a bit. I did some research and I've made a Memtest check for about 15 minutes (I know it's not as long as you'd expect) and I got zero errors and nothing out of the ordinary happened since last night when I did this check. Temperatures were steady at about 57 degrees Celsius with a full load and in stand by I was getting my CPU heated at about 45 degrees Celsius and my GPU at about 51 degrees Celsius. I have attached the minidump archive which is I think what you guys will try and work with.

If you guys will need any additional information then please reply and it will make the highlight of my day bringing it here and helping you to solve my case.

Best of regards,

Snuck.

STOP 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA http://www.carrona.org/bsodindx.html#top

Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

In looking through your drivers, I can see that you are using Avira antivirus software. Third party antivirus known for causing BSODs. Please remove it for testing.

If you need a BSOD free antivirus, you can use Microsoft security essential:

Please remove Virtual Cd program such as Deamon tool or Alcohol 120% . They use sptd.sys, which I could found in loaded driver and well known for causing BSOD. Use this tool to remove sptd.sys

I have done all you said and I think everything went well. Also ran the system file check and the verification went 100% well. It is telling me that the check did not find any integrity violations.

I will return here and post if anything out of the ordinary comes on my screen. I will check this pretty often though if any of you might find any other problems in the minidumps I attached.
