Not so much a matter of "never need to" as "can't". With a Mac, it's not nearly as simple as taking the cover off, replacing a part, and putting the cover back on.


High end graphics cards are mainly needed for the latest games and since the Mac can't play them, you really don't ever really need to update your graphics card!


This is going to come as a surprise to the people at Valve who've just opened up their website, Steam, to Mac users.

That's seems to be slowly changing since the passing of Steve Jobs.

I've heard that when the next MacBook comes out it will only cost $2k to level up Smile

Mac's aren't bad at all. The one major reason that at one time years ago that Macs were preferable to PC's was because they handled grapics softwear better, but that advantadge was gone longe aog and now in general, PC's actually surpass Mac's in that department. Not to mention that Mac's aren't user friendly when it comes to user customization and upgrading, and because of the lack of competition, the prices on a comporable Mac vs. PC are quite large. The light up Apple logo on the case is pretty cool though...lol.

I finally got around to replacing my video card yesterday. I got the Nvidia GeForce GTX550Ti card. It was pretty easy to replace. Thanks to all the input and advice given above. My old card was about four years old and was starting to malfunction. I was getting a faint, green grid on my monitor. Also, some videos or pictures would have green rectangular splotches in them (especially in Google Earth). I've learned these are all signs that a video card is starting to fail. Since switching in the new card, those problems have all cleared up. One problem still persists, however, and I thought the new video card would fix it. Every so often while watching a video, my computer will just freeze. The video stops, the sound gets stuck at that moment, and the keyboard and mouse are unresponsive. To get out of this, I have to manually power off the computer and then restart it. This just happened again earlier this afternoon after the new card has been installed. I am now thinking that my keyboard and mouse might need to be replaced. I haven noticed that my mouse sometimes won't work by not letting me move the cursor to where it needs to be, etc.. Could a mouse and/or keyboard cause video problems like this? Seems unlikely, but I can't think of anything else. Often when the video freezes, I will have been moving the mouse pointer aimlessly around the screen while watching the video. This is why I think there is a connection. Any thoughts? At least I know it's not the video card now! Smile

It could be so many different things. Might be bad memory, corrupted drivers, Windows needing re-installing, etc. etc. My first guess would be flaky memory. Memory is so cheap now that replacing what you have with more memory, (if your computer will handle it), could be a relatively inexpensive improvement and test.

When you get a total freeze like that, it's something fundamental. It's tough to say what the problem is, but certainly a new mouse or keyboard won't solve it. (Nor will other peripherals, like a new monitor, new speakers, etc.)

In my opinion, it's unlikely to be a software related issue either. Corrupt drivers or an OS issue usually won't freeze an entire system down to the mouse/keyboard/power switch.

I suspect it's bad memory. That would explain the intermittent nature of it... the problem only occurs when something tries to read or write to the bad sector. Fortunately, it's easy to test: There's a program called memtest86+, available at http://www.memtest.org/, that is free and pretty easy to use.

If it's not bad memory, you might as well try re-installing the OS. If that doesn't work, hate to say it, but it's probably time for a new CPU.
