Pc Freezing up / Crashing out of nowhere

During games mostly but sometimes just having a few tabs of a browser up my pc will freeze for about 5-20 seconds, sometimes no noise, sometimes the sound will continue like it's normal, and sometimes it does a really loud buzzing sound. Most of the time it is triggered by opening up a game or when a game gets intense.

Event viewer stated that I was getting Kernal Power 41 critical errors saying that the pc suddenly shut down due to a loss of power or the system has rebooted without cleanly shutting down first due to stopped responding, crashed, or lost power, so I rma'd my PSU and got a new one, same issue, but "sort of" less frequently. Some days it would do it once a day, others nothing. Today while playing league of legends (a game that isn't intense graphically at all, especially for my system) it happen 3 times.

My hard drives aren't fragmented, my temps are all fine at the time of freezing, usage of all components are fine as well. I'm going crazy. Is this a ram issue? Please I need some help.

Some attributes of the crashes include the games playing like they are REALLY straining my system, like 5fps for a few seconds before crashing. One weird time was when I opened rocket league up, started a match and a minute into the match the game started playing awfully for a good 30 seconds, and I was able to exit the game without crash.
 



It literally restarted as I was typing this with nothing but chrome open

Specs:
i7-4770k
980ti
16gb ram @ 2000mhz
msi gd65-z87 motherboard


It restarts whenever it really wants to I guess. My cpu is water cooled and it never gets above 45c while my gpu sits at 83c since the day I had it and has never overheated to my knowledge. But for most software that is just always running is shadowplay, corsair keyboard engine, killer ethernet, and my sound, so pretty much bare essentials and whatever game I have up.

The only changes I can think of is I got rid of VoiceMeeter and I updated windows 10 after a really long time, probably more than a year. It was working fine before and I was fine with it, I just didn't think something like this could be connected to it.

I had made a system restore point in case anything like this were to happen but my pc made a new the day the issues started popping up and it erased my custom one, so it restores back to pretty much where I am now.

I have ran memtest for an hour, I haven't overclocked anything. Going to try prime95 right now. I also just downloaded CPUID's Hardware Monitor, I will be researching normal voltages as well. How would I check if my uefi updated? Not too familiar in dealing with that.

Here is the HdwM when my pc is idling running nothing but chrome and the other bare bones I mentioned previously (except I accidentally had wallpaper engine up) https://imgur.com/a/e6ZHp
 
You can download the latest version from website for motherboard manufacturer. It's likely not the issue, but can iron out bugs. Probably includes Spectre and Meltdown patches as well. Speaking of, it's possible the OS patches for these are causing issue. I've read that Haswell users were getting BSODs currently from these, and recommended to avoid for now for Haswell.
 


Alrighty, should I just roll back my windows while I'm at it? Seems like this would be a good bet.
 


Been running prime for about an hour now, still no errors. I know that normally you would run this for upwards to 12 hours but I really don't think it's a cpu issue. And thank you for helping me out so far, it's hard to get someone who is dedicated to fixing a problem such as yourself 😀
 
Just trying to help :) I agree on Prime95 for now, an hour is plenty to weed out an OC that isn't very stable. What about a bootable Memtest86 test? It's what I use. Same with RealBench. Do you have any dumpfiles you could upload? Some folks on here are great at deciphering the culprit if it's driver or software related. Also, even after being replaced, what PSU model do you have?
 


I have memtest64 but I have not made a bootable with it nor have I used RealBench. Its a Corsair CX750M. I also just read that graphics drivers might also be a cause so I updated those and recorded which ones I had last just in case. I do not have any dump files that I am aware of, you have to create those right?

Okay so I just fininshed 2 hours of memtest 86 and it came back no errors everything was good.

Is this what you meant for a dump file?

I see you mention the PSU. I must say they are on the lower end of quality. It's possible you got a bad replacement unit, but they aren't recommended for gaming rigs or OCing. Just basic units, and they are currently listed as Tier 4 on this site. I would definitely try multiple GPU driver versions if you haven't already as well. To be honest, you would need to Google the minidump files, created from BSODS, as I'm not 100% on how to generate them.
 


I don't overclock anything, and I haven't yet experienced a bsod :/ Although its not the best psu, I've had this pc for 4 years and it has never done this until now. Even after the replacement, so it just seems suspect that it would be the psu, I would love for it to be the psu but idk how to test that.
 


So I updated my gpu drivers and so far no crashes or weirdness for 5 days now lol. I guess since I never updated windows I just never really updated my gpu drivers since they were mainly fixes for 10 series cards. Thank you for your help and different perspective on things!
 


Here is a list of all that I can think I have tried

Replaced psu
Gpu Drivers
Some registry edits

What I think it may be

Windows 10 update
Maybe ram
Maybe Psu
Maybe mobo
 
Have you done a complete OS re-install, forgot if you did at this point. I doubt it's DRAM based on your testing. CPU failures are rare, and you are not OC'd. PSU is replaced, but not that great of quality. Does board show voltages in UEFI? Have you tried removing GPU all together and using onboard video just to test?
 


I haven't tried taking out the gpu, I'm pretty sure the board shows voltages in uefi I'll check those out. I haven't tried rolling back the windows yet.
