I am really sorry for the issue.
If the Windows* memory diagnostic tool found an issue then it is possible one of the memory modules is not working properly, try testing one of the memory modules at a time.
When a Blue Screen of Death occurs usually is a good idea to test with the minimum hardware configuration or undo recent changes. Therefore, you may also want to remove any additional devices such as wireless adapter or others. Then, if the issue does not occur you may add one device at a time until you find the culprit.
I hope this helps.
