I have Time Machine, so i have an external harddrive with everything from 14 days ago so thats a good sign, the data is ok i think. I lost probably a few days of SugarSteem reworks and some photos here and there, but overall i think that is ok. Its more about can the OS be booted or am i screwed... I did recently replace the RAM on it and upgrade it, though was not having issues before from it, and on amazon it stated it was completely compatible with data to back it up on that. its corsair. hmm I dunno, i think i need to hit a diagnostics center or possibly get a new one... I DO have USAA Military insurance on the computer with a . $250 deductible so worst case i get a new one, but id like to salvage the current
