Hi and welcome to SF!
This is a pretty common issue with window 7. One of the thing I would like you to try is to do a system file check: SFC /SCANNOW Command - System File Checker
You have some out of date driver

The first 2 drivers
are belonged to Lenovo thinkpad Power manager drivers. Please download a newest version and install. I used to do that with my computer and it fixed the BSODs.
The 3rd driver I listed is belonged to SMI Driver for Lenovo system and the last one is belonged to Lenovo Parties Service Access Device Driver (SMBIOS). It can be an utility from Lenovo, take your time and find it on the lenovo driver website.
If none of the option work, I would go for a repair install
Here is one of the thread I used to work on, looks exactly the same as yours http://www.sevenforums.com/crashes-d...e-screens.html
