So I recently bought a new power supply, and replaced the old one. When I finished I restart the computer and got to the MSI bio screen, I set everything to default, and exited the bio, but every time I do that, the computer boot back to the bio screen, instead of boot to the window screen. When I press F8, the screen says no profile to load.
what make is your pc , before going custom built I have some Packard bell pc's , I could get different boot menus etc to come up by tapping f5 at power up but the manuals did not state this , I found out through geek chats.
I would suggest downloading a version of Linux and burn it to a CD / DVD and boot from it. Run as a "live" system - Do Not Install. This will then enable you to view your SSD and copy data off to another drive.
Then use a Windows disc, you don't mention which Windows you are using, to run a repair of your system.
