SSD Drive Now Showing as Removeable Drive

2 days ago my Desktop PC with Win 7 Ultimate booted but nothing showed on my screen. I thought that it had to be either a problem with the screen or the video card.
I plugged my screen into my wife's PC - All good!, plugged my wife's screen into my PC - Nothing!

I then removed all the cables from the rear and took it outside and blew away the dust bunnies.
Removed the RAM and cleaned the contacts with a plastic eraser. Re-assembled the PC and booted it, Nothing! I then removed the sticks of RAM one by one and booted, Bingo! the first stick was not working.

However, my C: drive is now showing up as "Safely Remove Hardware" on the taskbar.

My son-in-law setup my BIOS for me, but was unable to fix the C: drive showing up as "Safely Remove Hardware".

How do I make my SSD C: Drive show as an SSD drive and not an SCSI drive on the Taskbar?

My system:

Operating System: Windows 7 Ultimate 64-bit SP1
CPU: Intel Core i7 920 @ 2.67GHz 58 °C Bloomfield 45nm Technology
RAM: 4.00GB Dual-Channel DDR3 @ 532MHz (8-8-8-20)
Motherboard: Gigabyte Technology Co. Ltd. EX58-UD3R (Socket 1366) 34 °C
Graphics: BenQ GW2760HL (1920x1080@60Hz)
4096MB ATI Radeon RX 570 Series (ASUStek Computer Inc) 29 °C
Storage:
465GB Samsung SSD 860 EVO 500G SCSI Disk Device (SATA (SSD)) 34 °C
232GB Western Digital WDC WD2500JB-22REA0 SCSI Disk Device (RAID )(Software RAID) 41 °C
596GB Western Digital WDC WD6400AAKS-65A7B0 ATA Device (SATA ) 38 °C
Optical Drives:
16X52X32X52COMBO SCSI CdRom Device
HL-DT-ST DVDRAM GH20NS15 SCSI CdRom Device
Audio:
Realtek High Definition Audio

So does mine. I deliberately set all disks as hotswappable in bios.

It will be in the SATA settings somewhere

I am worried that one of my Grandsons will click the icon and remove the C: drive.
If they were to do that, what are the consequences?

It will tell you it is busy. Can only eject disks that are not in use

Thanks SIW2, you have put that fear to bed.
