I have some basic noob questions about adding an SSD on an existing PC with a hard drive. My mobo is an MSI 785G-E53. I have had some issues accessing the BIOS and have had to reset the CMOS to do it each time. Question: Is Version 3.9 the latest MSI driver for this mobo? My PC is running WIN 7 Pro 64 bit on a HDD that also includes MS Office and other downloaded programs. I have freshly loaded WIN 7 onto the SSD (Sammy 850 EVO 250GB) from DVD drive after selecting AHCI in the BIOS. Now installing WIN updates while the HDD is still disconnected. I will adjust boot drive order to make SSD priority. Question: What do I do with the OS on the HDD? OK to leave it on the HDD? Should I install Office on the SSD? If so, can I have the data (outlook.pst, Word, Excel files) directed to the HDD? How? What do I do with the Office program on the HDD? What about downloaded programs that I paid for? Leave on HDD? Download onto SSD? Thanks.
