Hi,

Could be heat related so add a small fan to the mix to see if that solves it.
Also check the Power Plan

Look in the Event Viewer to see if anything is reported about those.

Check memory problems

Memory management issues can also cause a BSOD in Windows 7. Thankfully, Windows 7 has a Memory Management Diagnostic tool that detects and solves problems related to system memory.

Click on the Start button on the Taskbar.
Type "Windows Memory Diagnostic Tool" or "Memory" (without quotes) in the Search box or,
Click on Windows Memory Diagnostic Tool (in the search results).
Click on "Restart now and check for problems (Recommended)".
The system will restart, and you need to follow the instructions given on the screen.
