- The operating system must be installed from the original image . In other cases, I do not provide technical support.
- Actual versions of hardware drivers (downloaded from official sites of developers, or installed using Snappy Driver Installer )
- Actual updates for Windows, this is especially important on Windows 7 and Windows 8.1
- Visual C ++ 2005-2008-2010-2012-2013-2015-2017 Redistributable Package
- RuntimePack Lite
- .NET Framework
Most importantly, do not use “optimizers” like Windows XP    Manager, AusLogics BoostSpeed, Advanced SystemCare, AVG PC TuneUp (TuneUp Utilities) and the like, if you do not know what you are doing. And if you think you know, then think again. You will not get any increase in speed, but you can easily add problems with the work and installation of programs. I repeat: use only those functions of these “optimizers” that you are sure of. And for easy cleaning of the system from temporary files, I recommend CCleaner + CCEnhancer.
So, if you are doing well with the above, then ask your question in the comments, describing your actions in detail. Be sure to specify the operating system version and installation method. A very desirable screenshot or, even better, a video problem.
