Hi Welcome to Seven Forums.
To help us help you would you please add your systems specs? Here's how: System Info - See Your System Specs Under System Manufacturer/Model Number add whether it is a desktop or laptop and whether self built. Log in to Seven Forums and you will be able to transfer the info directly to the specs page in your profile from within the System Info app.
After doing this your specs will be available in each of your posts. Click on mine in the lower left to see how it should look.
Full instructions in the tutorial.
This is so we don't have to search the thread for specs.
You may have a bad SATA controller on your board, MSIs are known to be troublesome. Try using a different SATA III port for the SSD.
Go to the MSI site and download and install their newest SATA and chipset drivers
