Howdy Yesterday my macpro 1,1 os 10.7 had a freeze - the 2nd screen got thin red lines running across it in both directions - diagonally I think Upon force restart I got blinking white start button- hmm I understand that's a ram error
Sorted out blinking white light by removing ram chips and then progressively reinstalling in pairs - Upon restart boots to grey screen Can reboot into 500 GB 2 nd hardisk ( os 10.5.8) Other combinations- Safe mode- shift key ( gets to about 25% left overnight Recovery - r key D key Option shift P R keys All Get grey screen freeze Can boot into system select - option key Shows hd 1 - 1 tb OS 10.7 Hd2 - 230gb is 10.5.8 HD recovery Backup efi ( time machine disk ?) Lion efi ( when USB Instsller stick plugged in) Except for hd2 all seem to get stuck in a loop of grey screen I removed hd1 and plugged it into MacBook and did hardisk check via disk utility - says all is okay (65 GB free) Does this likely mean the OS lion is corrupted and needs reinstalling Can I reinstall lion via the MacBook ( I have new tech USB drive adaptor set).? Also I gather I need another hardisk - can I use a WD drive from an external hardisk, or do I need to buy an internal sata drive? Or an ssd! Appreciate any advice.
