|How could it be a CPU overheating? Why does it appear ONLY in Opera -> Downloads window? I've been on the computer for about 2,5 hours now, and the sound only appears when I open the Downloads tab. :/|
I checked the CPU temperature, it is 58 degrees Celsius, so it's not very hot.
I have AMD Athlon 3000+ XP running at 2167 MHz (166MHz x 12.5x/13.0x) so no overclocking either.
The sound is quite silent, it sounds more like a bad fan bearings. The Opera - Downloads-tab activating the sound is the thing that puzzles me, not the sound itself.
