My msi notebook shuts down completely, don't even want to start up, after leaving it for a few days, it will come on again working perfectly for about 5 days, then the same problem will occur. It works for a few days and then I have to leave it for a few days before it will switch on. I had sent the notebook to the manufacturer but they could not find any problems, since it was in a working state at that moment. Any idea what could be the problem?
