When a system crashes you will usually see a Blue screen with some information and a Stop Code.
It will then make a crash dump file, it gets this info from a 'Memory Dump' and puts it a file.
If you follow the instructions below, we can analyze the dump files and try to find the cause of your crashes.
Blue Screen of Death (BSOD) Posting Instructions
When posting a new crash dump, include all System File Collection and health reports. They contain valuable information that we can use to find the cause of the crashes.
Post them here for now. If needed I can have the thread moved to the 'Crashes and Debugging' forum later.
You can also open the two monitor programs and play a game that is fairly stressful but doesn't crash on you, that way we can get some info on the CPU/GPU temps.
