Windows 11 PC will not start up even form flash drive

Come back from holiday to discover my wife's Win11 machine will not start up. Can hear a bit of grinding noise from the HDD . Opening the case the fans start running on power up for a few seconds then stop then try again in continuous loop. Only screen message is "no DP signal" no windows or manufacturer logo.

Things I've tried

Hold power button down for 30 sec. Detatch power cord and hold down for 30 sec
Hold shift on power up to try to get not recovery mode
Created USB flash boot drive using media creation tool. Press F12 while powering on

Has the hard drive failed or anything else I can try?

    Boot into the BIOS and check if the internal drive name is listed. If not, it means the drive is failing. You need to replace it.
