Q: G4 Dual 450 - Freezing

Yes, it has booted up and run for approx 10 minutes perhaps longer before freezing.

Sometimes it freezes immediately when loading up, and sometimes it gives me a few minutes and sometimes up to 10 or so.

It's very unpredictable.

Thermal paste??

Is that a job that I could do myself, and if so, how?

Or...would that be a job best left to a computer repair place?

Thanks.

UPDATE - So i backed up one of my other IDE drives and erased it, with the intention of installing Tiger onto it, and the error screen pops up again before i even get the chance to start installing the OS.

I was hoping that the Hard Drive was the issue, but that is not the case.

The main HD in my G4, had already been erased and had a few attempts at Tiger being installed on it and then froze.   I pulled that one out and had it fully zero'd and tested on an old G3 clamshell laptop running 10.3.5.    (which is the only reason i still have it - for diagnostics and repairs when all else have failed).

One of the other 3 drives (another 100 gig), i backed up on my MacBook Pro, and then deleted using the partitions in Disk Utility on my MBP.

I then installed it physically back into my G4, and tried to install Tiger on it...but it froze.

I wanted to try on a completely different drive, as I thought perhaps the original 100gig drive was potentially part of, if not, the problem.
