unzip downloaded file and double click on BlueScreenView.exe to run the program.
when scanning is done, go to EDIT - Select All
Go to FILE - SAVE Selected Items, and save the report as BSOD.txt
Open BSOD.txt in Notepad, copy all of the content, and PASTE it into your next replyDon't know if there is a connection but I looked inside the computer in question and its looks like the CPU / case fan may have not been working. Because there is dust all over the inside of the fan case and on top of the heat sink. There are also several capacitors by the CPu have brown rust on the tops and when i restart the computer the now see a message THATS reads: 

A disk read has occurred.
Press Cntrl+Alt+Del to resstart
