This is my first time posting a problem on these forums and I'm not the best at explaining things so if someone is confused or needs clarification, please tell me. I can also provide any needed information about my machine.
My problem started happening about a couple weeks ago. If I leave my computer on and alone for about an hour (this is the shortest amount of time I've tested with), when I come back, it will not longer function correctly. Attempting to open an already-open program from the task bar or use one that I already had maximized will not work and usually tell me that the program is no longer responding. Attempting to launch the task manager does nothing. The only solution I've found is to manually shut down the computer using the power button.
While testing, I found that already-open programs sometimes continue to function. For example, I left a timer open on my computer before I went to bed and when I came back, it was still counting up, but my previously-stated problems still occurred.
I thought I could solve this on my own, but I've tried everything I can think of. Again, I can provide any needed information about my computer. All help is appreciated.
Thanks!
