I have experienced a growing number of graphical issues.
1. In wow it start with glitches, but if the game continues, it ends with a complete freeze of the Imac, with no opportunity to exit the game or bring any other app. in use
2. Often when i start, graphic errors is displayed, like this one:
- notice the black around the box and the shades of grey in the left side of the screenshot. also, sometimes when i start the Imac, lots of squares in pink is in the right bottom of the display.
3. In Mozilla Firefox and Safari... thin crunchy lines appear from left to right, on top of all the content on the websites.
I have an iMac (2.16 GHz) with dualcore. I have a NVIDIA GeForce 7300 GT chipset from the factory (all is as it where from the factory)
I hope someone can help, it really drives me insane!
thanks in advance
