My old gameboy advance has started freezing sometimes, resulting in a looped glitchy noise. I recorded it at various positions ans distances around my microphone. Perhaps it'll be useful for you!.
An old laptop making weird sounds. It freeze, typing on the keyboard, than crashes and reboots. The fan was broken at that point. Recorded with an iphone 5c.
Wrinkled a plastic bag (home to rubber bands, who played no part in this recording) on my desk to try to make an ice freezing sound. Instead it sounds like stepping on cracking ice.
