I got this rx 550 and for the first couple of months, it was doing fine, but now my pc just keeps on restarting randomly. I dont know if it's my rx 550 or if it's my psu. But the person we got the pc from said that the psu is "generic" should we buy a new psu or a new graphics card? Because everytime I remove the graphics card, the pc is fine, no restarting. I need help, does anyone have an idea of what to do?
