A couple of months ago I purchased a Lombard off of eBay with 128MB RAM, 6GB HD and MacOS 9 installed. After receiving it I wiped the drive and installed 9.22.
Later I replaced one of the 64MB SODIMM modules with a Kingston 256MB PC100 module, upgraded the hard drive to a 40GB model and installed Tiger by putting the drive in a PowerMac G4, installing it then moving the drive back to the laptop.
Lately it has been locking up at random intervals doing different things. Sometimes it is while having several OS X applications running. At other times I am running Warcraft II under Classic mode. It can be anywhere from a few minutes to a couple of hours after being powered on. Each time this happens the only way to get it going again is to reset it using fn-ctrl-command-power.
Any suggestions besides wiping the drive and installing Panther?
