So I've had my Gateway Desktop (GT5658E
) for about 3 years now. Last year I installed an XFX Radeon HD 4770
but I forgot that I needed to upgrade my power supply with it. It still ran for awhile but then my computer started to make a grinding noise. At first I replaced my hard drive. And the noise came back. Then I replaced case fan. The noise came back. Then I replaced the CPU Fan. Yeah, the noise was still there. So Then I finally made the connection between my Video Card which needed 450 watts of power and my power supply which was a 300 watt. So I replaced it with this XFX P1-650X-CAG9
yesterday. But now its not working at all. I turn it on and it doesn't do anything. Nothing comes up on teh screen. I'm wondering if I plugged something in the wrong way. Plus the noise the PSU makes is LOUD. I can hear it through walls. I think its the new PSU but in the reviews I read it said that he fan should be fairly quiet. Is there a way I could've installed in wrong that would make so loud?
Here's some pictures I took, I can take more specific ones if you thing it would help.
Also, if I broke any rules on this board please let me know, I read them but maybe I missed one.
