Within the last two weeks I had to experience the following BSOD (blue screen of death) several times a day:
The error always came from the win32k.sys file:
*** STOP: 0x0000008E (0xc0000005,...)
*** win32k.sys - Address BF8E270C base at BF800000, DateStamp ...
I did a lot of web searches and found many users writing about similar problems. Upgrading the video driver as many sites suggested did not improve the situation but finally I found this Microsoft feedback entry. It got my attention because the users were working on notebooks with 2GB memory and Core 2 Duo processors too.
After I uninstalled the IntelliPoint mouse driver three days ago my system did not crash anymore – nice!
