In which direction to dig windows settings?

Question

Hard disks

They brought a computer.
Two screws: ssd 120 and hdd terabyte.
The first one was win 7x64 (7601). When installing different software, problems occur. For example:
1. Installed on hdd (disk D) Team Speak. It seems that the software works, but does not save data about the user profile (his rights, identifier).
2. Installed steam on hdd, does not save user data, every time I enter login and password. While the user's folder is on drive C (ssd), along the standard path. Windows username in Latin.
3. Installed Steam on ssh. All in and out. When installing games on a neighboring drive, for example gta, the games do not start.
4. When installing part of the software - Windows Installer error, although the services are all running, the rights have not changed.
And so it is possible to continue about any other software.
I demolished everything, installed it on ssd win 10. The problems are the same.
What am I doing wrong? Where to dig?

Answer 1

Thanks to all. The problem was solved by copying the necessary files to a separate screw and formatting. I ran chkdsk /r just in case.
Most likely the problem was related to NTFS permissions, as Ezhyg mentioned .

Answer 2

Where to dig?

Check at least the hard drive, and preferably both drives with a R. tester and see what it gives out.
This will already give either a reason for reflection, or the realization that you need to look somewhere else.

Answer 3

It seems to me that you have problems not with disks, but with which image of Windows you are using, fixing current problems and guessing which ones will come out still seems hopeless to me, so the advice is to try another installer.

Answer 4

How much did I understand the problems with the software installed on the HDD?
Perhaps the disk is fraying:
1.look at the disk errors in the Windows
log 2.Look at the SMART status of the disk.
3. Do a disk surface test, you can use the standard Windows chkdsk / r or any third-party.
