BSOD - 0x000000f4, not sure what I was doing at the time.

Hello Tombo.

Make it sure that the Samsung 840 PRO Series SSD is running with the up-to-date firmware.
Samsung SSD | Samsung Semiconductor Global Website

Do some Disc checks on the Seagate 1 TB and the Hitachi 2 TB.

1. Re-seat the sata and power (for the SSD, too).
   
2. Run chkdsk /f/r, following the option two of the tutorial Disk Check
3. Seatool for dos: SeaTools | Seagate download
   
   • Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.
   • You can use Win32 DiscImager to create a bootable USB and run Seatools for DOS. Follow this post to know how to make a bootable Seatools USB.
   
   
4. Post screenshots of all your SSDs and HDDs using CrystalDiskInfo - Software - Crystal Dew World.

Uninstall Marvell 91xx drivers in Control Panel > Programs and features. Then follow Drivers - Clean Left over Files after Uninstalling to remove all the leftovers.

Let us know the results.

Hello Arc, thanks for replying.

I re-seated my SATA leads and made sure they were in properly. Also my Samsung SSD firmware is up to date.

I ran the Disk Checks on all drives, everything seemed fine and there were no errors.

In SeaTools everything passed. Although I couldn't test my hitachi simple drive, probably because it's my external HDD and is USB?

I have attached screenshots of my drives as you have requested and finally I also removed the marvell 91xx drivers and cleaned the left over files.

Many thanks for your assistance so far!

Looks good so far :)
Now we have to wait and see how it goes.
