BSOD while idling, playing games

Hello Lain, to assist you better we are going to need your full System Specs please.

Please fill out your System Specs

   Information

Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.

If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible, making sure to click save at the bottom of the page. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task. https://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html

The requested page of kernel data could not be read in.  Typically caused by
a bad block in the paging file or disk controller error. Also see

If the error status is 0xC000000E, 0xC000009C, 0xC000009D or 0xC0000185,
it means the disk subsystem has experienced a failure.
If the error status is 0xC000009A, then it means the request failed because
a filesystem failed to make forward progress.
Arguments:
Arg1: fffff6fc4000b160, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc000000e, error status (normally i/o status code)
Arg3: 000000010afae860, current process (virtual address for lock type 3, or PTE)

The BSOD errors you are receiving seem to point towards Hard drive failure but could also be other things.

1. If you are overclocking stop immediately. After we resolve the BSOD, you can continue overclocking if you wish.

2. Please uninstall Avast and install Microsoft Security Essentials just to give us a stable environment for BSOD purposes. If you like Avast, reinstall after we finish. Keep one or the other, its never recommended to have two AV's on the same system.

Avast Uninstall Utility | Download aswClear for Avast Removal

Download MSE
Microsoft Security Essentials - Microsoft Windows

2. Verify your Ram is in working order. Download and run Memtest86+. I recommend running this overnight for at least 8 passes or until you receive any errors. Upon receiving any errors, stop the test, your ram or dimm slot is bad. Test the sticks of Ram individually to test for BSOD.

RAM - Test with Memtest86+

3. Remove all External USB/Internal drives connected to your PC that are unnecessary at least for now. Remove and reset connections to your hard drive (both ends) to ensure the cables are connected securely.

4. Run your hard drive manufacturers diagnostic utility and check Smart statistics and for errors (upload a screen shot or file and post it in your response)

5. Update your drivers for your motherboard and video card

ASRock > Z87M Extreme4

Video Card
Drivers | GeForce

6. Make sure your system is completely updated via Windows Update

Just out of curiosity, are you using Readyboost? You seem to be having issues with Readyboost at the time of a couple of your Crash dumps. If you are using Readyboost, can you stop and see if that helps?
