I am new here,I apologize for any grammar mistakes or stuff like that,English is not my first language!
So,recently I bought a new PC for myself and it was working well until today,I noticed that the mainboard was not working properly,I own anAMD Sapphire R9-270X 4GB.I don't know why or how this happened,I still think this happened because of the PSU(it's a 600W one)....Also,now,when I turn the PC on,the fans just run for a second and then they suddenly stop working..after a few seconds they work once again.By the way,it is booting onboard graphics..
Is the graphics card dead?Do I have to change it?
Is the PSU not giving enough power?
By the way..the BIOS doesn't recognize the graphics card.
