Before we address the above can you see if there are any crash dumps available for us;
1. Copy any dmp files from C:\Windows\Minidump onto the desktop.
2. Select all of them, right-click on one, and click on Send To> New Compressed (zipped) Folder.
3. Upload the zip folder using the Attach button, bottom left of the dialogue input box
If there are no crash dumps available you need to make sure that they are enabled "how to" below;
Right-click My Computer, and then click Properties. Click the Advanced tab, and then under Startup and Recovery, click Settings (or Startup and Recovery). For best results, under write debugging information selectfull memory dump. Your system however must meet several conditions for this option to work. Alternatively you can select small memory dump to have your system write out crash dump files that are significantly smaller.
You are welcome btw
