I upgraded all of my main components to my PC in the past few days, new processor(intel core I7-7700), new mother board(ASRock Z270 gaming k6), and a GTX 980ti Founders Edition. But after replacing my power supply and getting everything working, my new PC booted and ran perfect, but when i went to play a game from my D drive it told me I had to re install it, and when i went to check the D drive it was not there and replaced by an F drive I had never seen before and it only had 400ish megabytes left in its storage but in total it had 800 megabytes want this too work and cant figure out the problem i tried switching SATA cables around but still no luck I boot and run most programs off my SSD but use the D as a slave drive and mass storage center please help !
