I've switched power outlets, I tried power boxes and connected them both together n this js has me confused. It only happens when I play a game or it's under a little load. My specs are

-Intel Core i9-10900K 3.7 GHz 10-Core Processor

-Graphics Card - Rog STRIX 3070 ( Comes with original box)

-NZXT Kraken Elite 360 78.02 CFM Liquid CPU Cooler

-MSI MEG Z490 GODLIKE EATX LGA1200 Motherboard

-G.Skill Trident Z RGB 32 GB (4x 8 GB)

-NZXT H7 Elite Case

-EVGA SuperNOVA 850 GT 850 W 80+ Gold

-3x NZXT F120 RGB Fans

-RGB Lian Li Cable Comb

-500gb SSD
3TB HDD

Monitor specs are: 4k, 165hz 32 inches. Usually run it at 2k though

sounds like a graphics driver issue

#

ddu is the answer, display driver uninstaller

ill try it

If your PC is shutting off under load it can be several things.

The first most obvious thing to look at is your PSU.

The next thing would be your CPU. Your CPU could be overheating, depending on what cooler you have or it could be literally going kaput. I had this happen with one of my 11900Ks this year. (had to rma the cpu). The first thing i would do is make sure your bios is completely updated to the latest and the next thing i would do is start with a completely fresh intall of windows. This eliminates all software issues. If you're still shutting down under load I'd RMA both. If they aren't under warranty any more I'd try to get any other 10th or 11th gen CPU and see if you still have the same issue.

#

If the issue still exists then you know it's the motherboard.

No overheating, always at 50 or highest 60 temps. This was a recent issue and according to NZXT CAM and Task manager its at 41 idle so I doubt its overheating. I haven't updated my bios and I can't factory reset but I do have a spare ssd so ill try that

~~have you tried using a different wall outlet?

if no, try it first. if yes, ~~ ||didn’t catch the first part of the post that answered this literally lmao||

is the outlet on the same room or adjacent room? try another outlet that’s on a different area of the house like the living room for example. if this resolves the issue, then:

the reason could simply be an overloading of the circuit but not enough to trip the breaker completely. if that is the case, just check around the house near where the pc was plugged in. it doesn’t have to be on the same room, it could be the next room over or on the hallway. look for any new things plugged in specially high power draw devices and electrical appliances like portable heaters.

another reason could be the circuit breaker itself is failing or about to fail. one of the common signs a breaker is about to fail is when it temporarily disconnects power and not completely trip then restore the power back within seconds without any intervention.

#

Not sure if its because my GPU drivers were deleted clean off but its slower and freezing up, so far no reset though but ill update after running a game

#

there could be an issue with one or more cpu socket pins. i dont think it's ram related since that would normally cause a system crash/freeze forcing a full shutdown

possibly a voltage regulation issue, which means again, motherboard problem

Sounds like he needs to leave hwmonitor on and logging to see if any particular part is overheating or over/undervolting when it does crap out a strix 3070 and. 10900k can pull sum pretty good amounts of wattage maybe the PSU can't keep up under load n shuts off but since it's monitor too ide say get rid of the extension cords all together and plug it directly into the wall for awhile and see if it's just to much/long power cables

#

Extension cords can cause to much resistance and heat and end up shutting down before they catch fire

knotty thorn
#

it could also just be an over heating gpu, which seems like it's getting more common lately for 30 series cards. i doubt it's power issue into the power supply

#

i hadnt read what the gpu model was before, but now im thinking probably overheating gpu that can correct itself sort of. i think it may be right on the edge of being full shut down

#

i would actually install msi after burner or some other program that can lower power limits or gpu clocks to see if that makes it run longer. i'd also install gpu-z to log sensor data to see what temperature the gpu has it's issue which will be in the log file, found by looking for a sudden drop in gpu temp, which indicates where the gpu crashed and recovered or if the system full shuts off or crashes

icy glade
#

It very well could be that but there needs more tests to be done to pinpoint anything

knotty thorn
#

it's a good chance of it being the gpu, but yeah, we need the OP to test things first. im coming off my own personal experience with 2 30 series gpus doing the same thing and both requiring repasting on the gpu. i think even my gtx 970 is doing the same thing but that card may have become defective over time, so im not sure on that. never got around to properly testing it

round meadow
#

Started a game

#

And bam

#

Turned off again

round meadow

round meadow
#

What kind of test should I do

knotty thorn
#

roblox runs on a potato

#

but since the pc turned off quickly

round meadow
#

Yeah, I figured it was maybe because it was on load since I previously tested it on Warframe on 2k

#

So for it to turn off on Roblox is surprising

knotty thorn
#

it means that when the temperature ramps up the system either had a problem with power delivery or the gpu is overheating

#

the more likely cause is the gpu is over heating

round meadow
#

You're saying it's overheating but it's not letting me know?

knotty thorn
#

when you suddenly dump power into a component, it will heat up fast

#

if the thermal paste between the gpu and the heatsink is dried out, it becomes ineffective at thermal transfer

round meadow
#

So it can also be a dried out thermal paste issue?

knotty thorn
#

no the issue is most likely dried out thermal paste causing the possible overheating

round meadow
#

I did get it from someone who said it was new but didn't end up using it as he got another one as a gift

#

I've had it for maybe half a year now so I'll check that out

knotty thorn
#

if it's not thermal paste it has to be that it's clogged with dust and hair

#

and it could be a combination of both issues

round meadow
#

No dust around it, although changing the paste might take me a second

#

This is a big gpu

#

No dust but there is this much paste

round meadow
knotty thorn
#

the paste is dried out

#

this is what my 3090 looked like before i put in a graphite sheet instead of new paste

shitypaste3090.jpg
#

my 3070 was similar

#

if it's not the gpu over heating, repasting is not gonna hurt things

#

oh and before i was thinking i was reading the guy with a laptop with a similar overheating issue, which is why i mentioned dust clogging it

#

anyway. the 3090 was overheating but was still functional technically. running games made the system shut down or freeze

#

same for my 3070

#

although the 3070 lastest longer before that

round meadow
#

Bet

#

I think I'm out of extra paste

#

I'll go buy some and see if that was the issue all along

knotty thorn
#

if you plan to keep the gpu got a long time, i'd consider using a graphite sheet or ptm7950

#

i used thermal grizzly's kryosheet. thermal paste is cheaper than those 2 other options and you would just reapply if the gpu overheats again

round meadow
#

I hop from pc to pc

#

Looks like the thermal paste did it though

#

No instant shut down

#

Ill keep running it and come back if it appears again

round meadow
#

And now it just shut down again

knotty thorn
#

sounds like it has mounting pressure issues

#

the pcb may be slightly bent

round meadow
#

I havent changed the cpus

#

I'll check out the cpu and then gpu again

knotty thorn
#

no i mean mounting pressure issue for the gpu heatsink

round meadow
#

I didn't tighten this top piece cause the bottom screw is stripped

knotty thorn
#

make sure you fully and snuggly screwed in all the screws around the gpu

round meadow
#

I can still remove it but I have to do it carefully

knotty thorn
#

oh well if you stripped the screw you will need to get that fixed

round meadow
#

Shit so it needs to be fully tightened?

knotty thorn
#

also make sure you have the correct screw driver bit

round meadow
#

I was hoping it'd be fine

knotty thorn
#

nah that is literally the most important point of contact that needs pressure

round meadow
#

Damn well at least now I know the issue

knotty thorn
#

you might be fine if you swap in ptm7950 actually

round meadow
#

I'll just try and find another small screw like that

round meadow
knotty thorn
#

it's a thermal paste replacement

round meadow
#

Why do i need to replace it? I just swapped it out

knotty thorn
#

it's a phase change material that goes soft when heated to fill in gaps in the surfaces

#

it may allow for better contact if you truly stripped the screw threads, especially in the heatsink mounting screw hole

round meadow
#

I would still have to find another screw since i'm selling this PC

#

I'll check the thermal paste out though

knotty thorn
#

you can or should be able to find them for decent prices

#

when you say stripped do you mean the head?

round meadow
#

I can hardly turn it so if i truly screw it all the way down

knotty thorn
#

that means you used the wron screw driver bit

#

you need a philips # 00

round meadow
#

It's like this

knotty thorn
#

bro...........................

#

if it doesnt budge, dont keep trying to make it go

round meadow
#

A little less like that since I can still KINDA turn it

round meadow
knotty thorn
#

if it does that, get the right tool

round meadow
#

Which is why its not mounted right

#

Was hoping itd be fine but looks like i need another screw

craggy raptorBOT
round meadow
#

it's a very very tiny screw

#

These are too thick

knotty thorn
#

wait hold on wrong sscrews

#

i had the wrong link

#

i dont remember what the threading is, you may need to get a set of them

round meadow
#

Oh man

#

Hopefully the issue of it shutting off again is only this

#

Thanks though, it helped me locate the possible issue

knotty thorn
#

i would say it's a good chance of that being the problem

#

you will probably need to repaste it too

#

just to make sure it didnt separate out

round meadow
knotty thorn
#

get more paste when you get the screws. the paste can be used for other stuff

round meadow
#

But

#

The top screws are the same as the heatsink screws

#

So what do you think?

#

I could take one from a corner

knotty thorn
#

as long as it holds down the x

#

just dont do it til you have the correct screw driver bit

#

philips 00

round meadow
#

And it had to be the drill bit I lost that I now need

#

I can't use another one?

knotty thorn
#

the screw heads are 00 size

#

larger will strip them

round meadow
#

I think they're fine

#

I felt good and they feel like they went all the way in, only thing is that I can pressure it more because it's a larger bit

#

Taking out the old stripped screw completely ruined it though

knotty thorn
#

if you are gonna do much work with this kind of thing, you really need the correct tools to not do damage

round meadow
#

So that screw it garbage now

knotty thorn
#

the screw drivers are cheap

round meadow
pine dagger
#

if u have a stripped screw head and not have the correct bit size, use rubber band

#

rubber band on top of the screw head, sandwiched between when you place the driver bit, then turn it really slow with a downward pressure, it’ll come off. don’t use the same method to tighten though.

round meadow
#

I'll have to order another Phillip and probably more of these screws if the issue appears again

round meadow
#

I'm about to crash out

#

Alright so I reapplied the paste, now it doesn't instantly shut down and I can actually play longer than I do

#

Temps go higher, fans spin and there's no visible issue with the GPU now

#

I'm lost now

#

@knotty thorn Last issue was fixed

#

Now its overheating

#

Valo is straight 75-80 degrees

icy glade
#

need dat ptm7950 now

round meadow
#

Nooo 😔

knotty thorn
round meadow
#

Fans werent spinning at ALL

#

I ran it with gpu tweak and temps went down

knotty thorn
#

no fan spin means you might have messed up the fan cable or didnt plug it in if you unplugged it or it came loose

#

fans only spin when there is load

#

or at least they is how they're suppose to work

round meadow
knotty thorn
#

so check the wire

round meadow
#

I reconnected it correctly when i applied the paste

#

Thats when it just didnt spin at all

#

I opened gpu tweak though and then it started spinning

#

Then temps went down

#

So i think now its good
