Random Freezes and Shutdowns

[Bunraku]

Hi

 

Had my PC for a few years and had no issues.

 

About 2 months ago i changed from Nvidia GTX 970 to RTX 2070.

 

Not sure if cause as first month was great, but last month my PC has been having 3 kinds of problems.

 

 

BSOD with Stop Code Errors.

 

stop code kernel security check failure

 

PC just freezing. CTRL-ALT-DEL having no effect and having to hold power button to reboot PC.

 

 

 

I have run CHKDSK

 

Sfc /Scannow

 

Uninstalled Anti Virus

 

Verified Drivers

 

I have no hardware attached to PC apart Keyboard and Headset

 

 

 

Reinstalled Windows and now don’t seem to get BSOD.

 

However still get PC freezing when playing Call of Duty and GPU temp was 71° at moment of freezing and i had only turn PC on a few minutes before and the temps usually go higher no issue. I’ve also since played it for 3 hours since with no freezing.

 

Using Powerdirector for video editing my PC froze and again only turning power off fixes it.

 

And just Random Shutdown yesterday trying new Total War Try yesterday. PC just shutdown. Fans still turning, but black screen. Had to turn off at power to restart.

 

 

 

Any ideas whats the issue?

 

Thanks

Hi and welcome to ExTS.

 

It sounds like your machine freezes when doing graphics intensive proceedures.

 

1. - If you have a spare Video Card try replacing your present one with this.

 

2. - It could also be a RAM issue.

If you don't have enough RAM this could cause freezes.

If one of the RAM modules if failing this could cause freezes too.

It seems that your problem has already been solved elsewhere.

 

There is no need to post in 3 or 4 forums.

You are just wasting people's time.
