I have a HP Pavilon 516x with Windows XP. I forget the exact mHz and memory, but its around 800 or so and the memory is standard for that model and generation. It a little old, but it does what I need it to do.... that is until it makes a strange, hi-pitch squeeling noise inside of the tower and everything on the screen freezes in place. It's been doing this for quiet some time, as my brother as told me. He also suggested that it MIGHT be an inside cord problem (well, he said a way to 'temporary fix' it was to wiggle the inside cords around).

Is it a cord problem? Is it the CPU? And can it be fix on the cheap? I want to be ABLE to write stories WITHOUT it freezing in place!Well, we can't quite see it from HEAR, but it sounds like the power supply, eh?Unpossible! We installed a new power supply last December/January months ago.What brand is it? How many watts? THe important thing is amps on the 12v rail and the maker as there are a LOT of cheap bad PSU's.Things that can generate audible noise inside a PC:

• moving parts (fan, hard drive)
• speakers (note that modem cards may have a built in speaker)
• anything producing high frequency electromagnetic signals (e.g. GRAPHICS cards and power supplies)
