I am a relatively new mac user. I seem to understand and love the operating system a lot but I have one recent problem. My mac has been running slow. When it does this I fix permissions, repair disk, and reset PRAM. The problem is that this seems to happen all too often... like more than once a week lately. What could be going on? It also seems like every time I verify the disk it finds some problem and I have to put in my OS X install disk to repair it. After I do these things my mac is back to running great and 40ish second boot times. If anyone has answers or has been having the same problem let me know. I am running OS X 10.6 on a new 13 inch MBP 2.4Ghz. Thanks.

Well this might not be the answer your looking for but copy the OS X disk to a flash drive that's what I did cause I'm always on the go and I've been having the same problem.

Your drive may be failing. Check diskutil like so: diskutil check disk0 | grep SMART or diskutil list if you have multiple drives.
Your RAM may be faulty. Use another computer to download and burn a copy of memtest86. Boot into memtest86, run it for at least 2 hours. Some RAM issues can take weeks to surface. However, from the timeframe of your symptoms I believe you should be able to stop testing after 8 hours if no errors are indicated.
You may have a malware infection. Macs aren't immuned, despite what people say. There is now irrefutable evidence of Macs being infected. Malware infections can cause strange symptoms.
Those are the two most likely culprits. It could also be your mainboard or CPU causing problems for your HDD or RAM, or it could be your PSU causing problems for your mainboard, RAM, HDD or CPU.
