Hi everybody, I hope my post makes sense, it's kinda long so please bear with me. I bought a macbook last December 07, (Leopard preloaded, 111 Gb HD, 59 GB free space, 2.2 Ghz Intel C2duo, mem 1GB 667 mhz DDR2 SDRAM). Since I started using it, I noticed some issues, it would restart by itself but I didn't really pay any attention. 1 month ago: well, all of the sudden the machine would restart twice a week. When the machine started up, I would see a report notification due to MacOs restarting, I would click Send. hoping the issue would be fixed. 2 weeks ago it would restart 3 times in 10 minutes. Sometimes I was using word, sometimes I was trying to back my data (obvious reasons!), hoping it would let me do it but no, most of the times, the machine would restart. I did permission repair, nothing, it says the HD seems to be okay. I had ran OnyX, it says my mac is okay. I decided to archive and install, followed all the steps... nothing, it would restart again, just right after I started up. I decided to erase all the HD and install Leopard again, well, during 2 days the mac tricked me and i thought the machine was finally doing fine. No, today has restarted 3 times, while working with Word (didn't save 3 pages of my data, arrgh!) and also when playing a videogame (yes, Im a big procrastinator) and the last time when i was trying to back up my data. Im traveling right now so I can't take it to the Apple store and I do need a stable machine to keep working. Any suggestion to fix this nightmare? I'd try everything! (until I get to the US and take it to service!) Thank you for reading!!
