My computer recently started making a weird noise when it starts up. When I turn it on it makes a loud revving noise and either A) shuts down on me, or B) my computer starts up and runs with no problems. I though maybe it was a bad connection to the PSU but that is not it. I havent checked the fans yet. and I think the HDD is making a weird noise but more of a humming not a grinding. Could it possibly be the CPU? I have an AMD FX 8350 and I have it OC to 4.4 GHz and it was running stable for three days so I didn't think it was that but I really don't know. I f you have any further questions let me know and if you know what the issue is please let me know.
