System slow down after adding a new HDD

[Caronte]

Hello everyone,

I recently bought a new HDD 1TB WD Blue, 
After installing it the system started slowing down drastically.
Please note that i use an SSD as a boot drive and is not full 256gb 840 pro using widows 10.
sata module is AHCI and before installing the HDD the system was blazing quick like allways.

I also attach some pics of the system bios settings and some pictures of the type of system slow down i'm talking about.
Programs work just fine is only the system very slow and showing grafical artefacts.

Thank you in advance.

It's not your pc slowing down, it's a windows 10 bug. Sometimes when you add new hardware, the memory will max itself out and blue screen. You normally have to reinstall windows.
