iMac freezes but mouse still moves?
Background: Fresh install of Snow Leopard, replaced HD, upgraded RAM, ran all test on TechTool Pro 7 and everything PASSED.
Problem: iMac freezes but I'm still able to move mouse cursor but can't use mouse to select/quit programs, no response from iMac to mouse or keyboard commands. Otherwise iMac running fine. Any suggestions?
FYI: Activity monitor shows minimal load on Memory & CPU.
Thanks in advance.
1. Put back old ram is not on option. I no longer have it.
2. Drive is compatible.
3. Firmware is up to date.
4. No solution yet.
