It probably is just your fan you hear. They get old and dusty and make noises. Try cleaning it with canned air.
Get used to the noise or play a radio or tv in the background. You may want to replace your fan if it keeps bothering you after a while.
Computer makes car idle noise
My computer makes car idling noises (drrrrrr...)
Hi. My computer, ever since I 'revived it from the dead,' has been making a... strange noise.
It sounds like an idling car. It just goes "Drrrrrrrrrrrrr..."
It used to be just every now and then, and it seemed to be on specific occasions - For example, I clicked a button on WinRAR and it made this noise.
It doesn't go away until about 3-5 minutes pass...
Now, it happens ALL THE TIME!!!
This is really annoying. It isn't REALLY loud, but my computer isn't in the family room or anything, there is no background noise to distract me, either...
The noise goes on for 3-10 seconds, stops for like half a second, and repeats.
COMPUTER SPECS:
CPU: Intel(R) Pentium(R) 4 CPU 3.00 GHz (32 Bit)
RAM: 512 MB (Stock)
Graphics card: Intel(R) 82945G Express Chipset Family
OS: Windows XP Service Pack 3
BIOS Version: A06
Make: Dell Optiplex
Model: Optiplex GX620
I have tried to turn the performance mode (I think it was Acoustic noise or something similar) from performance to bypass, ad this seemed to start the issue, but it didn't work.
I tried going to this symptom diagnostic partition that I (THANKFULLY - SCORE DELL) have on my PC, and it turns the fans to high, then low. No difference in the noise, on low I still hear it.
It then tries stopping the hard drive, but the PC still makes noise. I am stumped. What else could make this noise???
