Does the iMac use the standard ATI 2600 Pro video card? On ATI's website it says that the card has ports for surround sound and blu-ray directly on the card. If so, is there a way I can open the iSight slot-loading 20" iMac that doesn't have the screws in the bottom without destroying the system so I can get to those ports?

Are there any ports that aren't available on the sound card? Is the sound card an integrated Intel chip or something else?

In a Mac Pro, does the hardware have to be from Apple? For instance can I go to Wal-Mart and get RAM that just matches the specs, regardless of whether it says Mac-certified or not?

ATI Connectors

No, there's probably no way to access those connectors in the iMac. Are you sure you read the right specifications too, because I think the 2600 is too old for Blu-Ray. As I remember, it was introduced with the 4000 series earlier this year. As for surround sound, that'll just be handled on the sound card, either external or built into the motherboard/logic board, not through the video card. Even today's video cards don't handle sound even if they advertise it: they just pass it through an HDMI connection.

As for the sound card, it's probably integrated onto the motherboard. However, it does come with optical capabilities, so you'll just need a mini-Toslink to Toslink cable or adapter to use standard optical sound, which will carry a surround sound signal.

As for the RAM, it more than likely will work, but Apple certification is convenient, because it's guaranteed to work, other than possibly guessing the wrong type of RAM. For example, the Mac Pro uses (at the time of this writing) fully buffered DIMMs (FB-DIMM) with error correcting code features (ECC vs Non-ECC). Many RAM sticks you'll find in retail stores are standard DIMMs and non-ECC, which I believe will not work in the Mac Pro (a quick Google search will tell you). If you are able to find compatible memory sticks, they should work, but I don't know if they'll be supported by Apple should anything go wrong.

For third party RAM, that is guaranteed to work with a specific Mac, take a look at:
to name just a few.

Lifetime warranty and a decent price, certainly better than Apple, and the RAM they sell is guaranteed to work in the Mac they say it will. Full money back otherwise.

The Video card thing? No way you are getting at that without destroying your Mac and I doubt if it has any of the ports you are looking for anyway.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
