For the past few weeks, multiple times daily (4-5x), I've been constantly having problems with random freezes on Asus N76Vz notebook @ Windows 8.1 x 64 with latest updates. I don't remember updating any drivers or installing any software that could be capable of doing that, so it has begun out of sudden.
 
Freezes are actually pretty weird. It starts with a partial freeze, i.e. I can still switch between opened programs, I can still open new tabs in Chrome (it won't open any new sites though, just rotating circle icon), winamp will keep playing music etc., actually all programs will freeze only partially, nothing like I've ever seen before. But I can't close any currently opened programs or open new ones, including task manager. Explorer (+Classic shell) will freeze (become completely non-responding) as well, so sooner or later, I will have to force shutdown computer and turn it on again.
 
I really have no idea where to look at because there's not a single minidump report.  S.M.A.R.T status is telling me that SSD (with latest firmware) and HDD (0 bad sectors) are completely fine (checked with Hard Disk Sentinel). Computer is not infected nor have ever been (Comodo Internet Security for active protection, also scanned with malwarebytes, hitmanpro, TDSSkiller and adw cleaner). I have the latest BIOS and the latest drivers from official ASUS support website.
 
There are no other problems with Windows, except a lot of times I can't reboot Windows normally - it will stay at reboot screen forever. I've already tried few solutions I've Googled about, but none helped, including turning off hybrid shutdown.
And another problem unrelated to Windows freezing mentioned above. Sometimes I can't close an application (Winamp and iTunes mostly) and killing in task manager from Processes tab also won't do anything. But if I try to kill it from Details tab, I get "The operation could not be completed.  Access is denied." error. I've Googled about that one as well, most solutions were solved by unplugging USB devices, but I don't have any connected at all, so dead end here too. I've also tried with Unlocker and FileAssasin and they can't do anything as well in that case.
 
Since there are no minidumps, I've collected system, application and administrative events around occurrence of random crash. I'm also posting system summary and hardware report from AIDA64. Please have a look at them here:
 
Let me know if you need any other reports, I'd be glad to post them. Thanks in advance for help!

All indications are that you have corrupt data, ie: a corrupt hard drive.

You can try the conventional methods of doing a checkdisk, but I've never been successful fixing a corrupt drive with the new Win 8 system that does it while the machine is running, so the only good way to do it, IMO, is through a command, asking it to do a diskcheck, which will get you an offer to do the job at the next reboot, which is what you would do. You can copy and paste the following command into the command box.

chkdsk /r C:

I've just updated my dropbox folder with the following files:
 
sfc_scannow.txt - as you may see, no errors
CHKDSKResults.txt - not sure if that fixed anything
1st_boot_after_chkdsk.png - interesting thing, happened for the first time. Just after the CHKDSK ran, a bunch of identical CMD windows opened up on the 1st boot.

How is it running now?

Uninstall Comondo and install Avira.

You need to run sfc /scannow.
 
The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.
 
To run sfc /scannow in Windows 8 you will need to open the Elevated Command Prompt.  The easiest way to do this is to press the Windows key and the X key at the same time.  A menu will open with the option Command Prompt (Admin), click on this.
 
You will see a window similar to the one below.
 
elevatedcommandpromptw7_zpseba8c499.png
 
When the Elevated Command Prompt opens type in sfc /scannow (please note the space between sfc and /scannow), then press Enter.
 
If the scan finds no integrity  problems in the first portion of the scan it should stop, to be sure that the scan has stopped wait five minutes, then type in exit and press Enter to stop the scan.
 
If it does find integrity problems the scan will continue.  This will take a while, please have patience and allow it finish.  
 
When the scan is finished please post the log of this scan.
 
To find sfc /scannow log, type cmd in the Search programs and files box, 
 
cmd will appear above the search box under Apps., right click on it and choose Run as administrator, this will open the Elevated Command Prompt.  This will look simlare to the image below.
 
elevatedcommandpromptw7_zpseba8c499.png
 
copy and paste the following, then press Enter.  
 
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >%userprofile%\Desktop\sfcdetails.txt
 
This will place a new icon on the desktop titled sfcdetails.  Click on this to open the log, copy it and paste it in your topic.

So I just though that it would be nice to share how I fixed my problem. Steps I mentioned in previous post didn't help at all, so I did these steps:
 
- disable dynamic tick
- change all scheduled tasks to Win8.1 compatibility
- uninstall Comodo Internet Security
 
I'm not sure which one helped, but one of these 3 did, so far I didn't have any freeze at all. I already installed Comodo again and it looks fine so far. Perhaps I'll also try to re-enable dynamic tick to see if that was the real issue.

That's fantastic. I was not aware of the dynamic tick problem and I'm assuming that it was the culprit more than the other two issues.

Thanks for posting the results and glad to hear you got it worked out.

Good job.

 

PS: If you do the dynamic tick test, I'd love to hear the results.

You didn't post the requested MiniToolBox.  There should have been information in there pointing to the Dynamic Tick.  This is a known problem with Windows 8/8.1.  This is the culprit, you have already enabled the Comodo security, now enable the compatibility.
