Hey all. I have had some issues with my powermac dual 2.0s so I returned them and got a SP 1.8. It is great and seems just as fast for what I do but I Have been having some trouble with it. I have Tiger installed and after I played UT 2003 for a litte while when I went to exit out of the game the computer froze on the black transition screen. Force Quit key command would not work so I had to hard reset it. Then it did it again when I had some safari windows open and I had to do a hard reset again. Then last night when I went to put it to sleep it locked once again. I decided to open it up and check out the internal temps. The computer was running cool EXCEPT for the GeForce 5200. The heatsink on that baby was boiling hot. Could the graphics card be my problem?? Is it a had install of Tiger and I should reinstall. Any help would be much appreciated. Thanks Oh, and I upgraded the RAM to 1gig but I used Crucial certified memory and I never had problems with the RAM in the other G5s. Just thought I toss that in there. I'm also running 10.4.1 in case that matters as well.
