"iMac keeps randomly restarting"に関する回答My solution was cleaning the cooling vents to allow the system to breath — core temps didn’t approach the auto-cutoff. I suspect the interior boards and bits need a good dusting, too — that’ll be the next step if the exterior cooling doesn’t resolve things completely. Design flaw — too pretty for its own good so it can’t breath worth a dang — fans included.
"Black screen, power light on steady, no chime: POST / BootROM failure?"に関する回答Reseat the RAM. I've seen this behavior when the RAM was not properly reseated upon reassembly.
"Acer Recovery Disk.........."に関する回答Acer's 'method' of having the recovery data is to have the user make a recovery disc BEFORE the acer dies. A travelmate 4230 I'm working on has this lovely feature, which is utterly useless once something causes Windows to puke. Win XP in this case. So if you do not make the recovery disk ahead of time, and cannot safe boot into Windows, you are hosed and have to buy the recovery disks from acer. Next time, I'm buying an apple. At least they include the discs with their products.
