My compute, a 2.1 ghz G5 crashes continually, but never at the same time and during different tasks. I think it might be bad memory. I reinstalled everything yesterday. here is the kern panic report and the configuration for when the last crash occurred. maybe someone can decipher these and tell me what might be the problem.

Could be ram but that panic log is pointing to the CPU so it could also be a bad CPU.

[Daniel Armstrong] "My compute, a 2.1 ghz G5"

That machine is got to be about 6 years old. You could try some new ram but it that does not work then it is NOT going to be worth fixing. When I priced a similar repair on a near 5 year old G5 the cost was going to be just over $1000 so definitely NOT worth it.
