The same thing happened when I ran that one (computer immediately shut off), but no blue screen after this time. Could the fact that these tests won't even run be a sign of some problem?
I am going to explain all the changes that I made to the computer before these problems started. I think most of it is irrelevant, but I could easily be overlooking something that is important:
- Shut off the computer. Unplugged all USB, power, ethernet, etc. cords from computer. Moved computer tower out from the cabinet it was kept in.
- Noticed the cooling fans on side and back of computer were covered in dust, so I vacuumed the dust out of the fans.
- Removed original DVD drive and replaced it with a brand new DVD drive.
- Reconnected all USB, etc. cords to computer. Placed computer under computer desk instead of in cabinet to allow it to have more space so the cooling fans can stay clear.
As I said, most of that is probably irrelevant, but I figured I should mention it all. Could it be possible that I somehow loosened the video card (or some other part) inside the computer when I changed the DVD drive? Or would that cause the computer to not function at all?
