Hi leader2,
Click “Start”, type “%SystemRoot%\Minidump" (without quotation marks) in “Search” bar and press “Enter”.
Locate the minidump file that occurred during the most recent BSOD.
If it's too large, zip it up and attach in your next reply.
You may also find that no minidump file is available. If that is the case, then you will just have to test the system for a few days and see how it performs.
I don't think I can post this here as a text file OCD since it wouldn't up as a text file to post on my computer. So I attached it for you.
