T60: NIM parity Blue Screen

There are a lot of threads on this so many that it is very confusing.

I'm hoping there is someone out there with a T60 that has already figured this out exactly. The 50 page dell threads and other threads I have read do not have clear answers that I can find.

I get a blue screen every few days on my T60, that I reviewed here.

It was fine for the first 7 months. Even after that it wasn't regular not until dec of this year did things begin to act up.

I have checked the memory many times with many tools, no problems. Removed and cleaned the contacts.

The screen often has artifacts with the system halt (lines and dashes of var colors). Driver changes to the ATi X1400, seem to have some serious impact on how often it occurs.

I honestly can't remember which of these (in my log) were parity errors and which were something else... It certainly got worse after I installed a slew of drivers and a BIOS update via System Update on 2/22/08.

They were:
1.12 BIOS
KB929637
Thinkpad ABGN 7.2.127
KB941137
Active Protection 1.54
ATi moblity... (since removed)
ThinkPad Power manager
tvtsched.exe issue patch
Power Manager
Rescue and Recovery patch to optimize space allocation of backups
Rescue and Recovery 4.0 critical patch #1

The freq is once roughly once a day (could be twice could be once every other day...)

Happens most often shortly (within 30 mins) after returning from hibernation, but sporadic.

 

I'm having this happen on my x60 vista business all the time...
