X201T blue screen every couple of days [ Edited ]

[thcomb]

I recently got my x201 and every 2 days I get a blue screen for less than a second, resulting in the computer restarting. I've used the thinkvantage toolbox to see what errors and changes were occurring on the same days as the unexpected shutdowns, and every day it was Windows Defender changing an option from true to false. I disabled Windows Defender (I use another separate firewall and AV anyway) and updated all of the Lenovo software, including the optional updates. Two days later(today) the blue screen displayed, immediately followed with a restart. Windows Defender did not have a log entry, and there were no other entries that occurred on all of the other days that this has happened. How can I stop this? I bought the computer to take notes during classes and if I can't trust it to not restart during the middle of class, then I can't use it.

I'm current with all of the windows updates and the lenovo updates.

PC details: Windows 7 64 bit, 4 gigs RAM (1 DIMM), 250 gig 5400 RPM HDD, Bluetooth, Intel 6300 wifi, no multitouch

Thanks for the help

Thanks for that link, I'll delete Avast for a week and see if I have any more problems.

Like clockwork, 2 days later, I get a blue screen. Not sure what to check now. I deleted Avast yesterday and installed Microsoft Security Essentials. The idea of a Microsoft app conflicting with Windows seems pretty unlikely.

Any tips on figuring out what is causing the error?

seems kinda weird that it happens every 2 days. like maybe something is trying to update on a timer or something. are you using anything specific when this happens or does it just happen whenever you're doing anything?

you did say that you turned off windows defender, right?  that won't run right with mse.  you could try going to control panel, administrative tools, event viewer and see if there are any events recorded.  on the right choose view log and if there is a log file saved it should allow you to at least see it.  i see that you posted on a couple of different forums, any luck?

Thanks for the tip with the log viewer. I checked it and during the last BSOD, there weren't any other events being recorded just before. I'll go through all of them and see if I can find something.

Windows Defender has been completely disabled, you can't even launch the program manually as it is now.

Because it keeps happening every 2 days, I'm with you in thinking it has to be something on a timer. Just in case, I've been restarting more frequently to see if I can interrupt the cycle and make it happen more or less often. Also, it doesn't happen at the same time during the day.

The BSOD happens during both tablet and laptop modes and during all sorts of programs. Firefox, One Note, and even solitaire.

I'm getting some help on the tablet forum, but no solution yet.

I went through the older events and I am noticing a couple of system events occuring just before BSOD.

On the most recent BSOD there wasn't anything about the filter manager (maybe because I got rid of Avast?) but there was this:

These blue screens aren't occuring right after startup, so I don't know why it keeps happening a few seconds after the OS start up logs. The OS had been running for a few hours usually beforehand.

Also, yesterday afternoon I deleted Zone Alarm firewall. So I just re enabled the Windows firewall. If I get a blue screen tomorrow, it won't be because of 3rd party AV or firewall.

vsdatant is your zone alarm.  i just googled it.
