Question My Internal 1 TB keeps disconnecting and reconnecting when ever in use

[Cosmic2910]

Hey guys so i've had this one terabyte HDD, and ever since i installed a fairly broken Second hand GTX 1080 Ti that my friend lent me my hard drive keeps disconnecting and reconnecting, ive checked my power plan and set that is never idles, ive even reinstalled windows and redone all the graphics drivers and <Mod Edit> but it still keeps disconnection and reconnecting only when in use tho, so if im browsing the web which is on my SSD, the same SSD that windows is on its fine but as soon as i try launch a game from the hard drive it does its thing, but downloading onto it is fine

A Guess,
Your power supply is on the edge.
Your hard drive is failing
Odd though that you can write but not read.
Now, for everyone describe fairly broken
List your system specs, at the very least HDD Mfg/model and power supply!

specs
CPU: AMD Ryzen 2700x
GPU: Nvidia GTX 780 Ti
Ram: Corsair Vengeance 16gb 3200Mhz
Motherboard: Asus ROG Strix B450-F Gaming

and the Asus GTX 1080 ti turbo is technically 3rd hand and was sold to my friend second hand and he felt that it wasn't performing to its maximum performance, and as soon as I installed the GPU I used it everything started crashing so I took it out, and now my hard drive just keeps connecting and disconnecting
