I have purchased about two weeks ago a R9 290 and a FX8320 which are running stock speeds and I had a PSU that did not support the graphics card and plugged in a old PSU that did ( bought it cheap like a week ago ) and today just about two hours ago I bought a CORSAIR CX750 and my computer continues to restart please help me! I am scared to tell my parents and I have been trying almost everything.
