I have a Dell Inspiron 570 Desktop that I installed a new power supply and
everything was working until I tried to get online. So, I thought if I used the
system restore that it might fix it. But after the restore, it would not boot back
up. I've ran the diagnostics test and it shows everything passed, but on another
window it says this:
Info: The boot selection failed because a required device is inaccessible.
By the way, I had earlier, before the system restore, tried to install a small
Cisco wireless adapter, but the computer couldn't detect it on none of the USB ports.
I rechecked the power supply connections and everything seems okay as it
was working at one time, although there may something that I have crossed up.
Anyway, nothing that I've tried works, even the safe modes, will not work.
How can I fix this?
Thanks for any help that you can provide...
