Please follow the BSOD posting instructions and attach the relevant files.

Here is the file

The crashes were caused by your outdated AMD display drivers, install the latest version. Use the 15.3 beta driver if the regular stable driver doesn't the BSODs.

What you're getting is a TDR117 (Video Timeout Detection Recovery) which indicates that your GPU failed to respond in time. This can be caused by multiple factors including overlocking, defective RAM/GPU video memory or corrupt drivers.

Code:

BugCheck 117, {fffffa80094d91b0, fffff88006ec2e5c, 0, 0}

Thank you for your reply, I'll test it.
