frozen screen

After several computer freezing screens we're one week further. not able to work on my computer.
Tried many things to get it back to work, which did not help at all.
Went to the repairshop twice, which showed when I was there, that my computer was absolutely fine.
No problems whatsoever.
It was working perfectly.
Back home the computer was frozen all over as before.
Drove me nuts!
Until I let go.
Today I found out my trackpad caused the problem...(sigh10 times)...sitting stuck under another thing, which caused the frozen screen.
How foolish one can be!

Anyhow my blackbird was sitting upside down in the birdbath...
Had to wait one week to get it out.
