Hard drive issue

My Dell PC office computer has shut down. I keep getting the same screen.

Here’s what the screen says.

A problem has been detected and windows has been shut down to prevent damage to your computer.

Disable or uninstall anti-virus, disk defragmentation, or backup utilities. Check your hard drive configuration, and check for any updated drivers. Run CHKDSK /F to check for hard drive corruption, and then restart computer.

My computer experience is limited. I tried F8 and tried to work in the SAFE MODE- but it keeps coming back to this screen. I also tried to go back to the last GOOD KNOWN CONFIGURATION, but it goes back to the same screen.

Please advise what would be the next steps in getting my computer up and running.
