Suggestions for replacing slow iMac componets?
Novice needs some help here!!
My late 2009 iMac is running Yosemite 10.10.3. Machine was running a little slow, but otherwise fine. Recently, it has been extremely slow, with the little spinning colored ball running for minutes at a time. Ran it in SAFE mode and rebooted - no improvement. Ran virus scan, which indicates no issues. Checked the resource usage screen, and indicated I still had 2GB memory available. I can't determine the EMC number, as there is no label posted on the iMac, but presuming EMC2309 based on processor. Machine runs so slow that I cannot download any of the software listed for system checks listed on the threads posted here . Processor is 3.03 GHz Intel Core 2 Duo. Memory is 4GB 1067 MHzDDR3. I believe hard drive is NVidia MCP79 AHCI SATA 1TB. I am willing to put some money into replacing components into an otherwise useful iMac. Already backed up data to backup hard drive, and created a boot disk on thumb drive.
Looking to replace hard drive with SSD, upgrade/add memory, and replace the processor if needed. Need some guidance on components and memory. If I can confirm the parts, I believe I can follow the install guides here.
1) What SSD hard drive should I replace the old drive with?
2) Should I replace all the DDRM with new, and is so, with what? Or simply add 4GB more of the same memory to the remaining two slots?
3) Should I replace the processor with new, and is so, with what? Can the processor be upgraded?
Is this a good question?
