Okay. It's scanning now.

It said "Windows successfully scanned the drive. No errors were found".

Yes, I did that. When it finished, it said no errors were found.

Okay. Let me check emails first, and check for updates.

Okay. I am about to do this memory test. Follow all instructions from the link you sent me yesterday?
