About 3 months ago I was GETTING noises from my speakers like knocking at a door or a creaking or slamming door. The noises were very random and did not occur all the time. More anoying than anything. More recently I get a voice that sounds like SPANISH. Can't really identify what it is saying, but it is a brief phrase. I also can't link it to any particular OPERATION. I opened the control panels to turn off the sounds and the arrow on the screen started flashing on and off and another noise that sounded like somekind of vibration or alien death ray occured for about 10 seconds or so and then stopped. I was able to turn off all the sounds, but the voice was still present. However, when I rebooted this morning neither the voice nor any other sound has reoccured. I'm hoping that solved the problem, but it seems more likely that something is lurking on the hard drive that I just can't identify. Has anyone had a similar experience that can be of assistance?I'm thinking you have some malware that's causing it, because I've had that same kind of thing happen and once I ran several different TOOLS to clean up my computer, the weird sounds went away. Try running CCleaner. You can FIND out about it here: http://www.ccleaner.com/features

Some websites also automatically belch out sounds, but that's not what your problem sounds like. If you haven't already done it, download Ad-aware, Spybot, and AVG Anti-Spyware and run those as well. For best results, run them in Safe Mode.
