However, I am starting to notice brief flickers of the display also, but oddly, it only happens when the CPU is busy doing something or the disk is seeking. I can't get it to flicker by mechanical tapping or slight twisting. > > With Photoshop 7 in OS X, when I rotated a layer, my screen would > occasionally static out - horizontal lines would flicker across the > screen. This hasn't happened since I upgraded to CS. Thanks for your comments! Yes, I do agree to your opinions about possible "bus flood" in conjunction with hardwear malfunction. If I have good luck of determining any graphics cord loosening etc. during following weekend, I will post those findings into this helpful list. Happily I grew up taking things apart..and sometimes putting all back to square w/success, I'm prominent enough to take this dear thing apart too :) And happily again, there is plenty of documents available regarding display, logic board and its connectors/peripherals.
