Hello please help this has been happening for a while now and it is getting really annoying my installation of windows 10 won't let me open any applications but it is not frozen and there are no error messages but it doesn't happen straight away my pc will work normally for about 3 hours but then it will crash what ever application I am in without any error messages then it will start not letting me click on anything but I know it is not frozen because I can open the start menu but I can't open and programs from there I can't open task manager to see what is running. So my computer is basically useless unless I turn it off by holding the power button and that gets really annoying after a while. Both my CPU and graphics card are overclocked but it is nothing serious just a small overclock and it has been working fine for months with the overclock and it is not overheating because I dusted it 2 weeks ago and the CPU heatsink has 2 fans in a push pull configuration. Please help it is really annoying is my hard drive dying or is there a virus please let me know if you have any ideas thanks.

By the way this is not my main pc this is my seperate computer that I use on the side just so you know. But I do use it frequently for work.
