You have essentially done items 1-4 below

Since you passed memory and disk test it is likely that hardware is good.   How did this problem occur?  Was it after a power failure?  After installing some software?  After trying to do a Windows update?  I assume you are running windows 10.

Try running that "item 5 troubleshooting" as described to get the blue diagnostic screen to show up.  post back here if it does not show up

3F0 is disk problem.  I though the disk diagnostic passed.

I the disk cannot boot into the windows diagnostic then you need to downloadl windows 10 into a USB flash drive, boot the USB and then run a repair of your hard drive

Use another system and a 16gb flash drive

Do not install windows 10, just boot and run the troubleshooter to try to repair
