Ok, first of all I took my power supply apart to lube the fan because it wouldn't kick in. I had to flick it to get it going or else it would not spin. I put everything back together and turn the PC on and now nothing comes on the screen, and my HDD will make a noise going WANG WANG WANG and my DVD Burner makes a noise like is attempting to load. Does anyone know what this issue is? Again nothing comes on the screen for some reason. Thank you, please help! I am always having bad luck.
