Please be more specific in the tests you have performed, what tests did you run? Important is photos/screenshots for details one could easily miss.
Before suggestions are given I would like details about the tests and results
- For the memory there are multiple tests, all of them use different algorithms and thus provide different results.
- For the SSD, it is a drive and a drive has a few factors to look at before we can decide if it is or is not a possible cause.
- For the GPU & CPU the most important is the temperature and in some cases also possible errors that may show up in the stress tests.
FYI, it could very well be incompatibility given that your ASRock does not provide support for drivers after Windows 7.
Incompatibility is not a thing that occurs immediately, it can occur at any time when a driver doesn't function properly anymore regardless of how many reinstallations and versions are tried.
