HI, so about half a year ago I built my first computer. Several months in I started picking up a rattling noise when I start up my computer. It doesn't happen every time and it goes away when I tilt it or slap it a bit. Ive been coping with it so far but its starting to get annoying.

I know the sound is coming from the back half of my computer, probably either the heatsink, gpu fan, psu, or one of the case fans. My friend told me its the case fan that's lose but frankly I didnt do a great job putting together the computer and I wouldnt be surprised if it was something else. I did open the case a number of times however and I dont think its a wire getting caught.

Oh yeah the was this one time my computer made some horrible noise when I started it up one day and it refused to display anything but a black screen. It never happened again though and it sounded like something went wrong wrong with the harddrive or cd drive instead but im not sure. Dunno if theyre related but I thought it would be something that could provide more information. Anyways thanks for the helpss. Sorry for the typos and lack of punctuation im on my tablet :p

Edit: actually its more of a rumbling sound. My guess is that the sound is coming from the heatsink. I have one of those gigantic copper zalman heatsinks and it took me ages to install it. Aside from the rumbling sound I havnt had a problem with the computer.
 
Yeah can be a fan hopefully not the HDD. Did you listen to it rumble and open the case to see where the sound comes from (since you didn't indicate you *LOOKED* for where the sound came from other than 'inside the case'). If you aren't confident with how you put the machine together then you need a 'professiona' to do it. Strip it all down, start from scratch and ensure everything is properly seated, plugged in, etc. Really it isn't hard, but if you half-assed anywhere then you get half ass performance.
