Q: Strange screen artifacts then freezing on MBP 4,1 -have reset smc and pram and problem persists... only occasionally though???
Hi there,
Have been running 10.6.8 on my MBP 4,1 for some time without any problems. Recently, however I get recurring display artifacts which increase to an entire system freeze. Occasionally, with waiting, some functions return (cursor movement, and ability to force quit programs with option command esc ).
Have reset Pram and SMC, these occasionally will provide a fresh start but the problem recurs. Wondering if anyone has come across this before. As i mentioned it is happening frequently but not always.
Here are some pics
This will occasionally appear during startup:

This is when it freezes
This was particularly interesting ...;)
Any ideas?
Thanks a lot for your help!
