I have a power Mac 7200/120 I write on it mostly and a while back the og drives dies so I blue SCSI v2 swapped it and everything was fine. The motherboard seemingly died,had a friend in Finland send one here to America with a ton of funky candy. Anyway I threw that in and it worked fine. A few months later here we are, I'm reading and writing onto and off of floppy disks and the first time I was just doing a spell check and it studdered and then froze on the screen telling me there's a problem reading the floppy disk. Nothing works but the mouse still moves around. It just happened again but this time I was trying to save a new text document to a completely different disk with only one other document on it so there's plenty of space and it tells me again there's a write error and freezes with the only seeming solution being unplugging the computer and letting it do its disk aid recovery when I go to turn it back on. Idk enough to even start help plz lol

I've had three 7200 computers. My first one was a 7200/90, then I got two 7200/75s. From what I've heard from others on system7today, it's kind of a weird computer. I've had a lot of weird and annoying problems with the 7200s as long as I've had them.

Edit: I will add, however, that after upgrading to System 7.6.1, it's been much more stable.

Typically, the heat sink grease has turned to chalk with age and needs to be cleaned off and replaced. Machine is overheating causing random crashes. Probably runs longer from a cold start and then starts crashing more frequently after being on.

When removing hte heat sink from the CPU be very careful as it is not terribly difficult to crack the CPU. Also, don't press down when cleaning the compound residue off of hte CPU.
