I have just gotten my Aunt's old PC and I hooked it up with a monitor and keyboard (no mouse yet)
The first time it was booted up it worked fine. The second time though, showed me the old Dell screen, went to black, then it said "Disk read error, press CTRL-ALT-DEL to restart"
After pressing the combination of keys, it just kept looping into that message. I am not a computer expert so please give me a simplified version of how to fix it.
