Over the last month or so my iMac has been sort of acting up.
First the DVD drive was sort of flaky, working and then not working. Meaning that sometimes after a reboot the system saw that there was an ATA drive in the system, but no burning device. But for the last week it has been working ok. I don’t know if that is failing or not but I just backed up all of iPhoto and iTunes to DVD’s so it burns ok.
Lately though, when waking the computer up after it has gone to sleep sometimes it will lock up hard right away. Sometimes the mouse is responsive, sometimes not. Try to start a program (Safari, Mail, FF etc) and the icon bounces on the dock for 30 seconds then the computer locks hard.
Powering off the machine and restarting sometimes I get nothing but a blank grey screen. Other times I get the file folder with a question mark in it. Then I hold down Option when rebooting, get the HD icon, click it and the computer will boot fine. A few times I have pulled the power for an hour, plugged it in and it boots right up. I do that sometimes when the DVD is not recognized by the system and that seems to fix the dvd problem till the next reboot or whatever.
The other day I had to boot off the install DVD and had to do a repair of the hard disk. A verify said no packages found, and a repair failed.
I ended up in a terminal window and ran fsck manually which found and fixed some problems and I was then able to reboot fine. I have stopped letting the machine go into sleep mode and it seems to be ok.
System is running 10.5.5, SMART has verified the drive as ok, but I’m not sure if this is
a sign of a failing system, failing drive or what.
Any other Mac users out there with some ideas on what might be causing all this flakiness?
