BSOD athurx.sys ntoskrnl.exe error 0x00000050

Hi all. I have an annoying BSOD problem which I don't know how to fix it. It started few weeks ago when I was playing the elder scrolls v: skyrim. The situation is getting worst and it happens more frequently lately, even during normal use of computer. I have updated my video card driver, wireless network card driver as well as Realtek PCIe GBE Family Controller driver, but it still keeps happening.

I would be appreciated if someone can enlighten me where/how to solve the problems, as I cannot afford to lose my unsave works continuously.

My OS is windows 7 x64 oem
my system is about 4 years old.

attached dmp files and the performance report.

many thanks in advance.

Hi Panais, thank your for your help. sorry I didn't get back to you any sooner. I only manage to have my pc to run memtest few days ago.

ATHEROS drivers for Microsoft Windows (Atheros?????)
it is my tp-link usb wireless adapter.

Here is the news,
I followed your instruction to remove the panda and setup the security combination. It helped to reduce the frequency of BSOD, and a notification, 'Display driver nvlddmkm stopped responding and has successfully recovered' usually popup before it go BSOD.

I ran system check and fixed most of the errors.
and memtest indicated no problem in my rams.

After I google nvlddmkm error, tried several of fixes, it turned out it was the 3d driver which come with the nividia driver package was the source of trouble. This morning, I uninstall the existing driver and have a clean installation without the 3d driver. So far, I am free of any error.

I appreciate your help, thank again.:)
