Weird 'scrunching' noise after macbook wakes from sleep

[bsheridan]

This has just begun to happen about 3 days ago, have had my Macbook for ~8months.

When I wake my macbook from sleep there is the usual HD boot up sound, but then after that, there is this other sound which I can only describe as sounding like when the trash is emptied, though only lasts half as long.
It seems to be coming from the hinge area [below 'MacBook' text] or the screen itself. I thought it may be the speakers, but increasing/ decreasing/ muting the volume has no effect.
Just to mention seeing as the screen may be involved, I found 2 stuck pixels [side by side] yesterday but turning off screen then turning back on fixed them.

Using: MacBook C2D 2.16GHz; 120GB HD; 1GB RAM; Tiger 10.4.11

thanks, b.

Hmm i was gonna say its probably the optical drive noise but now im not sure. The only thing at the back towards the vents is the fan/heatsink and display inverter

Maybe the GPU is corrupted

Well after trying it again just now, there is no sign of it!
Its never been a problem with anything, just made the noise thats all.
