    My GFX card is down. I need a new one. I'm on a Mac Pro 2008 2.8 ghz Quad core.
    I'm still running os version 10.5.8.

    I want to get a apple radeon hd 5770. Am I going to have to upgrade to a newer os? I can only run in safe mode Is it possible to update the os in safe mode, or any other way to get a 5770 running with only being able to run in safe mode.

    its a ati 2600

    I'm running 10.5.8

    I think its my gfx card. Every once in a while my computer would shut down only when watching movies, viewing high res pic,s or running things to my 1080p tv,it would freeze, bring up a message and i would have to restart.( i don't have the error code) I'd some time get artifacts covering different windows sometimes whole screen then restart.

    I could hear, the fan on the GFX card struggling. I'm sure it was that fan. It just ran real loud. IT got worse and worse. Now when i try to boot up in regular mode it's louder than ever then the screen goes black and the monitor eventually says signal out of range.. After I couldn't boot up I cleaned it got a good dust bunny out ,but i still cant boot up. The whole computer needs a cleaning.

    Now it wont get pass the boot screen unless i start it up in safe mode.

    Right now i have a artifact box following my pointer in safe mode

    Hope its the gfx card, I wanted to upgrade it anyway.

    You'll need to be on the latest version of Snow Leopard, at least.
