Computer noise at startup

I bought this computer off an Ebay store where they assemble it for you. On cold mornings, it would make noise after turning on (power supply fan related). The noise would stop for a while. I got a replacement power supply (PSU) from the company and the noise stopped for a while. Now it's almost summer, it's not that cold, and the noise has started again. I'm thinking maybe it's not the PSU but maybe the flimsy case enters some resonant vibration? With the previous PSU I tried to buffer the spaces between the case and the PSU with tape, didn't do anything. With this new PSU, I tried to tighten the screws again, didn't do anything. I'm sure the noise isn't coming from the case fan, as, when I had the previous PSU, I disconnected that fan to make sure.
