Hi Everyone - I need some feedback please.
G4, dual 1.42, 10.4 .11,
2 Gig Ram
3 internal hard drives (120G (boot-up with over 1 gig free space), 500G1, 500G2. plus addtl firewire drives.)
23- apple cinema display.
DVD combo and CD drive.
A few weird things going on.
I get really bad intermittent pixelation and dotting on the whole display, mostly arranged in horizontal changing patterns. Sometimes it boots clean and remains clean till shut down, sometimes it boots dirty, sometimes it start cleans ad gets dirty. I open up the unit and move the ribbon connectors a bit but doesnt help.
(Display is OK- tried it on other macs and works fine).
I bought a new ATI RADEON 9800 Pro graphics card. Problem persists.
Problem happens when the unit is cold and just started up or if it's been running and hot for a while.
I DID notice that when I run the unit with the door (with either graphics card) the fan keeps runs faster and faster. When the door is closed the fan runs steady.
******
The internal hard drives intermittently do not not show up on the desktop.
(The firewire drives always show up fine.)
When I go to System preferences and select any of the other two 500G internal drives as start up drives, it still boots from the 120.
******
The DVD and CD drives intermittently do not show up on the desktop.
******
Another intermittent problem . I insert a CD or DVD. The window opens showing all the files. If I click once on a file, the file disappears. If I double click on a file it disappears and prompt says file cannot be found. If I eject and reinsert disc, files show up again.
All along Im running Techtool pro, no problems reported.
I tried zapping the PRAM. no change. I may need to zap the NVRAM(?) (anyone know how to do that please let me know.)
Ive also reinstalled the 10.4.11 system from scratch (wiped the 120 drive clean). Problems persists.
Any suggestions and help is appreciated.
