Further to my update 1 . a ram Board or chips are causing white blinking light on startup - how do I get them tested? Currently have only one ram board installed with 2x 512mb, 2 x 2gb chips installed.
2. I've reinstalled lion to 10.7.5 Now Safari on my main user account won't open. 3. When screen saver is activated - the system states to restart 4 . One of my iCloud email accounts [email protected] won't connect. Are these issues solvable?
