I upgraded my computer last night, replacing almost everything and installing a CoolerMaster Silent Pro 600W. All seemed well, when just randomly browsing the internet, my computer made a loud crackling noise. It sounded electrical and didn't seem to be coming from the speaker, so I thought it was the PSU (even though this particular brand is not known to have problems.)
With the power off I inspected my PC with a flashlight. I could find no evidence of capacitor wear or damage of any kind on either my motherboard, or from inside the PSU (from what I could tell.) I booted my PC back up and checked the voltages and temperatures (both in the BIOS and with SiSoft,) and everything seemed normal.
So then I ran SiSoft's burn-in benchmark suite for a good hour. Nothing, no warnings, no instability. Then I played Starcraft 2 with all settings on Ultra for a good hour. No sounds, no instability, nothing out of the ordinary.
I never heard the sound again after that. Is it possible a blob of dust got lodged somewhere and touched a component it shouldn't have? I did notice that the cable for a chassis fan was stuck under my motherboard something good, I had to tug a little to get it unstuck. There was a slight scratch on the cable from that, but certainly no burn marks. Could that have caused the noise? How worried should I be?
