My speakers are turned off
Suddenly there was a high pitch intermittent sound
lasting some 1 minute from inside the case
which terminated as suddenly as it started
does it indicate a warning of some disaster please ?
or was it just trying to brighten my dull day ?
Ian - thank you - it's just done it again - identical - the sound is high pitched - not like something mechanical - speaker like - I was not touching the PC at the time - about 3 hours in between - very puzzling - jarani
jarani - I'm stumped. Perhaps others will have an idea. The only other thing that occurred to me is that while your external speakers may be off, the PC still has its own internal speaker. I wonder if something is interfering with it? (Sometimes, when I have my mobile phone close to my desktop speakers, I get strange 'interference' noises - nothing like you're experiencing, but some sort of electronic signal close to your PC may be causing it).
My first reaction would be that it's likely to be mechanical and that a good internal dusting might do the trick.
You can, of course spend money and buy a Can of Compressed Air. Alternatively, a clean 1" bristle Paint Brush and a Hair Dryer may be found somewhere in the house.
Unplug everything > Take the PC into the Garage > Take the Side off, putting the screws into a saucer > Blast the inside with the Hair Dryer (Set on 'Cool') > Delicately use the Paintbrush to dislodge any recalcitrant dust > Being very careful you should be able to get the bristles of the Paintbrush between the fins of the CPU Cooler and onto the Fan Blades. Blast again with the Hair Dryer. > I have found that removing the Fan from above the Fins, that cool the CPU, to be mildly terrifying (for the first time) but effective.
I use a 3 cleans process. The First to shift the loose stuff. The Second, to shift the stuff that my brush has loosened and the Third, to shift the dust that I can now see that I have missed.
I should note that my PC is of the Land Rover, rather than the Lamborghini, Variety.
