So my husband built this computer for me, I know some very basic things but not many. Recently we installed Windows 7 from burned disks. I was unplugging the external disk driver from my computer when my msi bios popped up. It's an z270 gaming m5. My cpu is a Intel core i5-7500 @3.40ghz. My ddr speed is at 3200mhz. I can provide more information if needed. Hoping this isn't a major issue because he will not fix it so any help would be appreciated.
