Does anybody else have a noisy computer?



I get this static-y background noise when I am trying to transcribe audio files, and for some reason it seems to be getting progressively worse, and I am finding I have to turn the volume up higher and higher to hear. (This is not happening at all when I transcribe with my C-phone, so I'm pretty sure it's not my hearing.) I have no idea if it could be speakers, computer audio, or what, but it's little squeaky high-frequency, low-decibel noises and static-y noises, and it's making it harder and harder for me to hear past it. (I also hear a squeaky h.f., l.d. noise periodically when my computer slows down for something, which appears to be several times an hour when I'm transcribing, and I haven't figured out yet where that is coming from either, but I've had it for the past 3-4 months and it affects my expander when I'm working.

Does anybody know how to diagnose these types of problems? I did try plugging my earphones directly into the audio port and it didn't make any difference. Apart from that, I don't know what to check or how to check it.

TIA
