PC hard shuts down under cpu load

[cottontails2]

I don't know whats wrong, originally i thought it was my power supply, it made a rattling sound so i got it replaced under warranty and the new power supply works just fine, but my computer is still shutting down when i play games or try to convert a video file. This problem happens when the CPU is under load anywhere between 90-100%. I know it's not overheating i've used a few programs to monitor the temps and it hasn't gone above 70C! I recently replaced the CPU cooler from an Corsair Hydro H110 to an Cryorig H7 and the H7 seems to be working well and the fan spins at a pretty fast pace, but maybe there is problem with the H7 , because the hard shut downs started right after i installed it. The only other thing i can think of is the ram might be bad, anybody know what could be wrong?

@AliceNoel Hmm, if temps are not bad then it is strange? Make sure that the H7 is not shorting anything on the mobo.

Make sure that the H7 is not shorting anything on the mobo. 

What do you mean by that, how do i check? I mean the CPU cooler is plugged in correctly and there aren't any wires in the way of anything.

[dragoon20005]

open up the event viewer and see if any error pops up

 

@AliceNoel

 

can you take a photo of the cooler when it mounted?

[superfly06]

can u explain the shut down event ie turns off instantly, does shut down sequence or restarts

[cottontails2]

Maybe it requires over 750 watts to run properly, is 750 watts enough to run the H7, AMD FX8350 and the GTX 770 4GB?

Well, see if the metal fins are touching anything. Check for any metal form the cooler (including exposed wires?!!) and make sure they are not touching the motherboard or anything else. 

 

If not, take off and re-mount the cooler.

Well, the PSU is only Bronze however I am pretty sure that it should just about be enough (quality wise). Are you over clocking at all?

As soon as i run something that puts the CPU under load such as converting a video or playing games after maybe 20secs, it hard shuts down as if you were to unplug it!

what is the new PSU model?

 

750 should be plenty for your system

have you tried swapping power cables or change the power socket where the PC is plugged?

[superfly06]

2 things that i know of that can cause an instant off event is heat or insufficient power.

It's not touching anything and i followed the instructions on how to mount the H7 so i don't think it's mounted wrong.

Don't know if i'm looking in the right place, but i found a few errors?

Take down any overclocks you have, just reset the BIOS to stock settings and see how it goes there.

Download Speccy and AIDA 64, run Speccy to monitor CPU temperatures and AIDA64 to run stability test, tell me how it goes, what temps do you get and if it crashes

Your PSU is meh, but it should be fine with those specs regardless, especially after RMAing it.

Yeah the CPU is overclocked from 4GHz to 4.2GHz

Okay on it.

 

Whoops double post sorry.

yea that dont think that is the error we are looking for

look for other critical errors

With the overclock is the voltage on manual?

VRM degradation may also be the cause

What is that?

How long do i need to run AIDA for? I ran it for about 3min and speccy showed the CPU got up to 61C.

[dragoon20005]

What is that?

pretty much the circuit chips which provide power to the CPU and RAM

 

they are under the heat sink right beside the CPU

 

over time from the heat and voltages they will degrade slowly and wont be able to provide the need power to sustain a set clock speeds

 

so you may get throttling or sudden power lost when a high CPU load is applied

keep it running and see if the temps start creeping up

 

it may be a sign the cooler is not in contact with the CPU or the thermal past is not enough or curing fast enough

What can i do to fix that, if it is the problem?

VRM = Voltage Regulator Modules. These are the things that supply the correct power to the components. EG, a motherboard will have them to send the right voltages to the CPU. GPU's have them to send the right amount of voltage to the GPU etc. These are key and overclocking can sometimes harm them (depending how well made they are). Usually a high end motherboard will use "military grade" VRM's. To be honest, they just say that because it sounds better. But it will help, especially with overclocking.
