iMac running very slow even under light RAM and CPU load
A little back ground: I purchased this imac used. When I first powered it up the cpu fan was running at full speed and it had a firmware password. I was able to get passed the firmware password after a RAM upgrade to 4GB. I repartitioned, reformatted the 160GB HD, and installed OSX 10.6.8. I've also reset the SMC, NVRAM, ran virus scan, and repaired disk permissions and the imac is still crawling! I was able to repair the LCD sensor cable which fixed the high speed fan which I was told by a "Genius" would correct the slow speed but here I am.
FYI:
37 GB of 160 GB used
CPU 90+% idel
2GB of 4GB used
Any and all help would be greatly appreciated. Thanks in advance.
Mike

Thank you both for such a quick reply.
1.
I previous upgraded to Maverick but a "Genius" told me that this computer would run slower with that OS so I reinstalled 10.6.8.
2.
I've been working on trying to run the disk defrag with iDefrag and I finally got it finish the process but computer is still crawling.

I ran a test on HD and it has one bad sector with a report stating that the HD was failing. So I guess it time to get a new HD
Questions:
Would one bad sector cause the computer to crawl?
Is SanDisk SDSSDP-128G-G25 2.5" 128GB SATA III internal SSD compatible with OSX?
Thanks in Advance. I really appreciate your help.
