Sound / Audio

[#1]

Ok, this problem is so strange.

I format whole disk and reinstall OS three times, still the same.

I don't know when will it happen, could be 30min after I start windows and could be few hours later.

The problem is when it happen,

I can still hear the music,

but there are some "Bo-Bo-Bo"(I don't know how to describe) sound from speakers when I playing musics, videos or games,

sound more like distortion.

After I restart my laptop,

every things become all right, before that problem happen again.

My laptop is p505-8950 and OS is Windows 7 Unlimited 64-bit

I download drivers from Toshiba's website.

And I try to use my USB speaker(with built-in sound card),

then stop laptop's audio devices,

but the problen still the same.

I don't know why it could happen.

This problem just freak me out!

Please...help me...
