Error message when working with SDL Trados 2015 SR1 and SR2

Hello,

Ever since I upgraded to SDL Trados 2015, I've been having the following errors, which seem related:

(1) Every couple of hours when I'm working with Trados, the screen suddenly freezes and I receive the error message: "Device driver stopped responding". This message pops up successively 2 or 3 times. After I have closed it each time the screen will return to normal.

(2) Sometimes I will receive the error message "Device driver stopped responding" but the computer will no longer respond to my prompts to close the message. Instead, it will go dark and the computer will completely restart.

(3) The latest inception of this problem is that every few hours when I'm working in Trados, my screen will suddenly go dark and the computer will restart. At these times, I do not get any error messages whatsoever, the computer simply restarts on its own.

I had this problem when I initially installed Trados 2015. I installed SR2 about a week ago, but the problem persists. This problem (error messages / computer restarting) occurs ONLY when I'm working with Trados.

I contacted Hewlett Packard since my laptop is still under service. They tried to help me for several days, but were unable to resolve the issue.

Please help, this issue is seriously disrupting my work. I work with Windows 10.
