Annoying issues with SL. Can anyone help? Quick Stats 2.66GHz intel xeon "woodcrest", 9GB of ram. nvidia 7300 GT. (any other info available on request) Issue Ever since installing Snow Leopard I have been getting series of screen glitches. Random green/pink noise all over screen, missing top bar etc. Desktop wallpaper takes ages to load, freezing and the machine is extremely clunky. UNTIL I reboot 2-3 times. Then everything works perfectly and is blazing fast! All my apps run fine without trouble. Should I downgrade back to Leopard, or take it in to microcenter? Any help would GREATLY appreciated!
