Windows 7: BSOD bad_pool_caller

01 May 2011   #1

Windows 7 Home 64 bit Premium Service Pack 1
BSOD bad_pool_caller

I have gotten the BSOD bad_pool_caller three times. All three times I was watching a Netflix "watch instantly". I have followed the instructions on the BSOD posting instructions. Please find the requested files attached.

I could not find anything in the device manager for a Power Supply Unit. If you need it, let me know where to look. The last device that I added was a Logitech M305 wireless mouse.

Any help you can provide would be great. I look forward to hearing from you.

Thanks so much.

Appears that the cause is an Intel driver. Go to website and update it.

It appears the they file NETw5s64.sys caused BSOD and has been reported to them since January 2010. This happens for all operating systems (XP, Vista, 7) and probably all makes of computers. They do not appear to have a fix for it yet. Thanks for your time.
