Windows 7 BSOD after regular update around 13 May 2015

[Cryos]

I have a LeNovo X1 Carbon running 64-bit Win 7 and had problems with the fall 2014 updates that caused BSOD. Fixed that by removing updates specified here. After that the laptop worked perfectly without BSODs. Now since the latest batch of updates in May 2015, the BSOD appears again. The timing between BSOD is long, many hours, the previous BSOD problem gave BSODs at a much higher frequency. I am mentioning this to highlight the differences. I one more laptop and two desktops running the same setup of software but without these problems.So the question is simple, what may cause this resurgence of BSODs?

Hi,
every dump file points to the same thing and Mbm3CBus.sys relates to a (Ericsson) mobile broadband device driver. Yours is dated 2012. In fact most of your drivers are in need of updating and I'm pretty sure this is your support page:

Please double check it's correct download page and update your drivers.
