Computer wont boot windows

[CalebTheEternal]

My friends computer was working fine, he went to dinner and came back and nothing that was Windows would work, ex. calculator, cortana. He then restarted his computer and the computer will start it just will not boot into windows, it loads and says preparing for repair and when that is finished it goes to a black screen and that's all it will do. We took out his SSD which his OS was on and proceeded to install Windows on his spare hard drive, this worked for a few days, but earlier today the same thing happened. Now when he tries to put in the windows disc the screen goes purple and nothing will come up. We have tried taking out the GPU, cleaning everything, switching ram slots. Any ideas on what it could be? Could it be a faulty windows disc? Any help would be greatly appreciated. 

 

 

EDIT: His PC specs that I know:

i7 3770

ASRock Extreme4 Motherboard

MSI GTX 970

Corsair CX600M

Instead of using the disk, did you try grabbing the OS off of microsoft's website and setting up a bootable USB?

I think it may be some corruption, try clearing CMOS and flashing the BIOS

I will let him know to try that, I'm currently out of town and Im not sure if he has a spare computer to do that with.

maybe some sort of virus that is somehow embedded in the bios chip - it just disables post and stops the computer from starting? try switching mobos

so he tried a third hard drive and it seems to be working so far. 2 bad hard drives maybe? seems a bit odd.

Did he plug in his SSD to access the data on it after he installed windows on the 2nd HDD?

If yes, it is very possible that he has a Virus on his SSD.

Try to use an Anti Virus Boot Disk and run a scan!
