I have been dealing with this issue for a while now and it always happens in late afternoon time. I can't nail down a specific time but in the 3-5pm (today happened at 4:40) range.
I am using Windows 8 on a ASUS Laptop.
What happens is a few programs go unresponsive and change to the "Not Responding" bar at the top and when looking at Task Manager it usually shows a few programs that go unresponsive. I can usually exit a few Chrome windows but trying to switch tabs in Chrome or task manager just locks up that program. Most of the time the task bar on both monitors goes unresponsive so I can't get windows maximized again even using alt+tab or win+tab. Any window I try to close or touch goes unresponsive. When I am fortunate enough to have task manager open already trying to end tasks has no effect. I can still move my mouse around but I can't get anything done. Also the network seems to stop working when dealing with this issue and trying to refresh in Chrome just keep spinning but I can not confirm it goes down because the task bar has already gone unresponsive and is not doing any more draws.
When looking at the task manager during this issue, nothing is pinged out or using a lot of cpu, ram, disk, network, etc so it isn't just bogged down.
When the problem arises I have to cold shutdown my laptop (just hold the power button), wait a bit then power it back on and it seems to work fine all the way until I have to go to bed.
My main stay of programs open is usually Chrome(multiple windows), AIM, Skype, Task Manager. In the icon tray I have Norton Security Suite, Google Drive, Asus USB charger Plus, Asus Smart Gesture, and Asus Live Update.
I just ran ccleaner a couple days ago cleaning up the registry and disk cleanup. I have tried to use Task Scheduler to find what things go on at that time but I can't find a way to filter events that happen in a time. I have already turned on "All tasks History".
What can I do to diagnose this problem? (event or system logger/monitor?)
I had a hunch that AOL Instant Messenger (AIM) was the culprit so I no longer run that program and instead use Pidgin which allows you to chat with your same account on many chat networks including AIM. I have way way less freeze ups / unrecoverable unresponsive so I assume AIM was causing the issue.
