Windows 10: Hard freezing hard reboot required

Hi there,

I recently upgraded my PC to:
i7-8700k
MSI Tomahawk
G.Skill Trident 2x8GB 3200

Ever since I did the upgrade and fresh installed Windows 10 to my SSD, I've been having quite a few problems with this build, My computer sometimes maybe once a day hard freezes to the point where my cursor and keyboard do not work but I can see the last things I was doing on my monitor. No errors, No BSOD. Only a hard reboot will remedy this and no errors pursue after reboot.

I check event viewer and nothing really comes up related to as to why it might have stopped responding. I ran ram tests and it came back with no errors. I recently turned off C-states as I noticed it was reducing my clock speed down to under 1.0ghz at idle. However afterwards I had HWmonitor open I tried opening a game and the last thing I could see under the CPU load is all cores jumped high 90's on usage. I was not able to view temperatures at that current time but I was running a cooler master 212 and I decided after that hard freeze I was going to install my EVGA CLC 280. My idle temps are currently 33-38 degrees C.

I noticed when I went to the BIOS menu my ram was set default 2133 I believe I switched it to 3200, as the reason I bought the motherboard and ram I did was that the sweet spot was 3200 for the combination of those two products.
Now Intel boost is activated I believe hitting the speed to about 4.29ghz I don't know if this would have any impact on it.

I have updated my drivers, reinstalled some of the drivers I suspected were culprits. But I am still at a loss and am now looking to any of you for advice.
Thank you.

:)

 

Windows 10 Randomly Freezes Requiring Hard Reboot.

Windows 10 Randomly Freezes Requiring Hard Reboot. I have tried many fixes from power plan to clean reinstall. nothing seems to work. Brand new PC. Any help would be very helpful.

 

Computer freezing and requires hard reboot.

I got windows 10 and sometimes now it randomly freezes and needs a hard reboot, it's extremely annoying and I can't find a fix or anything. All I know is that I'm not the only one having this problem.

 

Screen freezes randomly, requiring hard reboot

I've been working on this problem for months now. I have Windows 10 on a HP Envy desktop and using an HP display. It worked fine without problems for about 6 months. Then the
screen started freezing-- the pointer freezes, the PC becomes unresponsive.
When I power off by hitting the power button and restart, it works fine for a few minutes to hours to days without a problem. Then the problem will happen again randomly. I figured it probably happened after a Windows update, which are automatic.

Then about 5 weeks ago it got a new problem. The screen would suddenly start flashing on and off, and the PC was again unresponsive. After rebooting, it would work again for a few min-to-hours-to-days as with the previous problem. Finally it went to a blue
screen with endless circles and would not ever get past that point. SO, at this point
I wiped the hard drive and reinstalled Windows 10.

NOW I'm back to the original problem: the pointer freezes and the screen freezes, requiring a reboot from the power button. The only software I have installed since reinstalling Windows:

Mcaffee Live Safe

Microsoft Office

Chrome

HP Printer software

Adobe acrobat

The problem has been happening from the beginning though (right after I reinstalled windows). So, I figure that the screen freeze is a Windows problem. I've updated all drivers. I've searched all over this site, but no suggestions as to what to do. Can anyone
help?
