Lenovo t500 BSOD Kernel-power issues (windows7 x64)

Initially I would have suspected memory and even though you have run memtest86 this is no guarantee it isn't memory , to quote since windows 95 Microsoft have stated about memory testing programs

Defective memory chips may not be detected by memory checking tools. Some memory checking programs are not adequate tests because they do not test RAM in the same way that Windows uses RAM. Most memory checkers use read/write cycles when scanning memory. Since Windows is executing code from memory, it uses execute cycles. Execute cycles are different from read/write cycles and are more vulnerable to parity errors. It is possible for memory checking programs to find parity errors if the memory is extremely faulty.

however your crash BAD_POOL_CALLER (c2) is often caused by drivers which have an invalid memory reference in them somewhere ?

named as the faulting module in your crash is

NETw5s64.sys NETw5s64.sys+e805 fffff880`05870000 fffff880`05f1d000 0x006ad000 0x4aafedb7 15/09/2009 20:40:39

which is your intel network driver and needs updating ?

also these drivers mostly pre-dating windows 7 release

are out of date and need updating ?


ssport.sys is a Port Contention Driver from Samsung Electronics
mdmxsdk.sys - Conexant Modem Diagnostic Interface DRIVER which if not in use should be unninstalled and disabled in your bios ?
Tppwr64v.sys - Lenovo TrackPoint driver
rimspx64.sys ricoh card dreader
rixdpx64.sys ricoh card dreader
rimmpx64.sys ricoh card dreader
smiifx64.sys - SMI Driver for Lenovo system
psadd.sys - lenovo SMI driver
e1y60x64.sys - Intel Gigabit Network Connection NDIS 6 deserialized driver
000.fcl is possibly a CyberLink FCL Driver or My Book Device Driver by Cyberlink Corp

most of those drivers can be found by going to lenovo support and downloading the most current versions ?

also can you tell us what antivirus and or third party firewall you are using ?

let us know how it goes :)

I have updated all the drivers from here Lenovo Support & downloads - Drivers and software - ThinkPad T500, W500. I have avira antivir 10 personal installed and no third party firewall installed (only windows7's own). I will wait and see if that wlan driver fixed it. Fingers crossed...

quick work let's hope this solves it
