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.
37 GB of 160 GB used
CPU 90+% idel
2GB of 4GB used
Any and all help would be greatly appreciated. Thanks in advance.
Is this a good question?
