Specs: Windows XP
Why is my computer making "one" strange scratchy chirp noise a minute or two after start-up? What is the cause and does it effect the performance?

It's probably either your soundcard or speakers sending a small 'surge' (for want of a better word) or possibly a background program sending something through that isn't working properly. Either way, if it only happens once then I shouldn't worry about it. If, however, it occurs more often then you need to troubleshoot it by first using headphones in place of the speakers - if the noise doesn't happen then it's a speaker problem. If no difference then start Task Manager and see if a program appears in the processes list at the same time as the noise. After that it gets a bit more complicated so see how you go with the above first.

Is it a "physical/mechanical" sound, like something expanding from heat and possibly contacting one of the fan blades of a cooling fan?

Hi Dan,

Thanks for replying, but no it's not that kind of noise. I think JohnR (?) may have hit the nail on the proverbial head with his diagnostic reply.

Again Thanks for the heads-up, in the event of a fan/heat expansion noise situation, I'll know what to expect.

Hi johnr,

Thanks for the feedback and diagnostics. I believe you have something there and I will implement your advise. However, if I just go into hibernation or standby and shut off my WiFi access and/or unplug my hardwire when I'm done computing, then I can totally avoid this issue. Which pretty much proves your diagnosis. The downside, I don't get my updates unless I shutdown and start-up with the noise again ~OR~ seek out my updates manually. Trade-off, six-o-one/half-dozen the other.
It's ALWAYS something...huh? ;p

Salutes and Smiles to ya for your Efforts!
