BSOD CRASH

Hello,
I have a few BSOD crashes for a long time , about 1 year.

Hi,

One BSOD blames lvuvc64.sys - your Logitech Webcam driver, however it appears to be up to date:

Code:

lvuvc64.sys                 Fri Apr 01 18:02:12 2011 (4D955C54)

I think that the real cause is something else, please turn on the Driver Verifier: Driver Verifier - Enable and Disable

Also run these tests:

RAM - Test with Memtest86+

Thank you for your response . i had run the memtest86 a few days ago without errors and i had run the intel processor diagnostic without faults.

i will turn on driver verifier.
