Maybe someone can push me in the right direction to a fix ? Or should I buy a new computer?
Today I decided to accept Microsoft's invitation to download and upgrade my windows 7 pro, unfortunately, it didn't go so smoothly as I had hoped it would!
It downloaded ok and also installed, as far as I could tell, then it rebooted. That is when it sort of went ka-ka
It restarted with the 4 window "panes" and the revolving dots, then a pop up window said something like " Change resolution to 1920 x 1080 (which is already the default) and then the screen went black!
The pc was still on and so was the light on my optical mouse. I left it for 3 hours thinking that it was still doing something, but nothing.
I then decided to do a new install with the Windows 10 that I downloaded to disk on Sunday.
This idea didn't work either because it wouldn't start the setup!
So I gave up and restored Windows 7 which I backed up before starting all this
I am on an HP Desktop Tower HP dc5800 with a Radeon X700/V550 graphics card.
Sorry it is so long.
