I have MacOSx version 10.6.8.
Processor 2.16 Intel Core 2 Duo
4 GB 667 MHZ DDR SDRAM
Graphic: NVIDIA GeForce 7300 GT VRAM (Total): 128 MB
It starts with lines located randomly on screen, black, or like monitor cracked. Then it happens like on screenshot - sprites of minimized window. I googled for similar problems and solutions, but haven't found satisfactory answer. It already went on service, but when it returned it continued with this problem. Can i you suggest some solution with installation of some program or driver or...?
