Are you saying that you actually think that changing an AGP aperture
overstressed your power supply?? That has nothing whatsoever to do
with your ATI card or PSU. Changing the aperture just allows some
system RAM to be used to hold data such as texture maps. It's RAM
that would be in use, anyway.

Are you saying that supplying extra power to an optical drive will
increase its rotational velocity beyond spec??
The CD blew up because CDs sometimes blow up in modern drives that
spin them up to 48X and beyond. It was coincidence, nothing more.

Nope, the problem is in the media. If you have a CD with a tiny crack
and spin it up to 52X, the centrifugal force might widen the crack
enough to make the disk break. When it breaks at that speed, it goes
to smithereens and usually takes the drive with it. Yours is not the
first drive to die such a death. This phenomenon started to be
reported when optical drives with 40X speeds were introduced.

I think that's what you'll end up doing, but if justice were done, it
would be the unethical shop that built your computer that would have
to foot the bill.
