This may be better suited to the hardware form (not sure) so if it is could a mod move it please.
I recently installed Folding Home and got the GPU version as well. When ever it running though the 8800GT make a weird noise. Its a high pitch noise (sort of buzzer like) but its constantly off, on, off, on.
If i put folding home on full it stays on.
I really have no idea. I've noticed it before at game startup screens (constant on) when its showing the devolper and intel/nvidia logo's but i've ignored it as its only for 5 secs or so.
Any help will be great
