Why does my mac stop downloading files, copying to clipboard, saving files to desktop, etc?

iMac g5 1.9 ghz 17" running 10.5.8. Had a hard drive crash and bought a new one. Loaded new OS leapord. Everything works fine at first, but after the computer has been on for a while, it will stop downlading files, disk verify doesn't work. I can't copy and paste stuff. It seems as if the hard drive is full, but I have only used 32GB of 300GB.

When I restart, it works again, then slowly not. Is it an overheating issue? How do I know if my fan is running? Is it a bad hard drive I put in it? Bought it new with three year waranty.
What's wrong? Please help.
 
Why not use iStat and the 'Activity Monitor' to see if the G5 if overheating or the CPU is maxed out.
 
nomenculture, with maxed out, I mean that some process might be hogging 100% of the CPU. Using the 'Activity Monitor' you might find a culprit.
