When I had memory added to my MacBook Pro, I started having kernal problems (comp. would not boot). When I took it back to company they said I had bad sectors on the old hard drive that caused problem. I replaced hard drive, everything is almost fine except when I want to update software the comp. will find what I need, download files. Normally it would then write the files and do a restart. My comp. never finishes writing the files so my system can be updated. Last time I tried updating my comp. spent 8 hours writing the files and never finished. Has anyone has this problem? By the way the new hard drive was cloned from the old one.

Hmmm, very suspicious,

Add memory and then have Kernal panics!
First step is remove the new memory, put the old memory back and watch that puppy boot correctly.

I'd suspect the RAM

I'd suspect the RAM myself. Since it's third party, Apple won't support it, but you could probably take your system to an Apple store and get them to run a diagnostic on it. Just make sure it's more than the piddly AST that they will run on most systems. A proper memory test should take 30-45 minutes, maybe longer depending on how much RAM there is to test. Take it in, get them to run a full diagnostic on it, and see what comes up.

While it's not out of the question, it's pretty uncommon for a bad HDD to cause kernel panics. So, something just seems a bit fishy about the story you've been told thus far. At least as you've relayed it to us.

Definitely the memory.
For the "company" to ignore this is hard to believe.
What "company" did you take it to?
If this is a newer MacBook Pro, I'd assume you took it to an Apple store or called support?
Did you tell the "company" that you'd changed out the memory?
