I downloaded it and it said to reboot. Now, my computer will not boot and I am getting a Floppy disk(s) fail (40).
Check the answers for that error message
***here***.
If you have a floppy drive in the computer, look at post #2 on that page.
If you don't have a floppy drive, look at post #4.
Help, I just had to "restart" everything due to a virus, so I am nervous! I can't even get it to respond to F8 for "safe mode".
I'm not sure what you mean by "restart" everything due to a virus. Restarting the computer does not get rid of a virus. Going back to a previous restore point isn't likely to get rid of it either.
When I tried to launch The Black Mirror again, the same freeze happened. I restarted my computer, but windows did not open-I got a screen with colors and strange symbols.
The only time I saw something similar was when I had a motherboard go bad. But it's not clear what happened to your computer yet.
