Pc crashes, burn history and help with new diagnosis.

[aniket111]

So i bought msi gt750ti in around 2016-2017, it worked very well with my fx 6300 up untill few months when i got my first burned 4pin cpu connector on motherboard, luckily motherboard was under warranty so got it repaired, next thing that got issue was 24pin connector, it was burned but this time, i bought new motherboard and psu wires were replaced by service center (psu was circle 450w) after few months it was my 750ti, it started to crash in solid color (dark blue, red, green, navy blue) then one day it completely stopped working as it was under warranty, i sended it to service center but they told me that it was not repairable and gave me credit note. Then i bought new motherboard and new gpu (1050ti) cpu and ram were same (fx 6300 along with 8gb of local vendor ram).

 

Then in june~august 2019 my 1050ti gave me issues, so sent it and got replaced, bought new psu too (corsair vs550 80+white) and bought a new ups for only PC, then it was rainy season here and one fine day i started my air conditioner and smelled burning so i called technician next day and as soon as he switched on the AC and there was short circuit in AC motor, my screen went blank and yet again 1050 ti somehow died along with the tv it was connected to ( i diagnosed that it was because of power strip not being connected to earth wire at the time)

Ups was working when this happened and pc was also running but gpu had no fan spin and tv didn't had display as it also got burn on hdmi port on pcb.

 

Again sent 1050ti got replacement, bought new TV and a heavy duty surge protector with ground, now in between this 1050ti lost a capacitor/resistor or some diod of some kind, took it for repair and the guy instantly fixed the issue.

 

So basically 3 times 1050 ti was already replaced and repaired

 

Now wait it does 4th time too ha!

 

In Feb 2021, i got a BSOD and had to manually shut and start pc, upon starting i heard beep from speaker and came to know that it was due to ram so i removed 1 stick and tried to boot and it did so i then cleaned surface of ram and reinstalled it and thats when 1050ti stopped spinning fan and didn't gave output. I heard beep of boot screen so i knew something was wrong with 1050ti itself, so i tested without gpu and with spare gt210 and it booted with screen both time.

 

Now to current situation:

 

i start pc normally, use it for sometime then it crashes randomly while on excel sheet or while gaming or just on desktop, it then restarts and i can hear speaker making boot beep but there is no signal, so i tried to connect tv to motherboard and was able to see display. (This is all while my 1050ti was connected and having spinning fan)

 

So next step i did was reseat gpu, nope didn't work, next i tried to reseat 24pin, got into bios and it crashed.

 

Tried gt210, it did same thing few times, but after few tries it started to give display and was no longer crashing.

 

Again reseated 24pin and put 1050ti

It worked, stressed gpu using msi kombustor, gpuz render test, unigine heaven and benchmark mode as well as story mode in assassins creed Valhalla, it didn't crash, so started fortnite, after 2-3 matches it crashed, again repeated same steps, it crashed on windows loading part, after repeating reseating 24pin and gpu, it worked again, this time it worked for whole week then after 6 days it started crashing, repeated same it worked.

 

 

Now my psu is corsair vs550 so i know it can handle 1050ti easily but yup i am out of answers

So please someone help me diagnose issue.

This issue is blowing my mind now.

 

I have already invested heavily on this rig

Since 2016 i have had replaced motherboard, gpu, ram, psu and bought ups too in 2019.

 

I think it is because of motherboard but i am not sure and due to covid, service center is not open so i cannot take it there to get tested.

I want to buy new ryzen 3600/i5 10400 along with new motherboard and ram but i first want to diagnose this issue and be absolutely sure.

 

 

 

 

 

 

Specs:

Gpu: Gigabyte 1050ti 4gb (bought in 2018)

Psu: corsair vs550 (bought in 2018)

Ram: 8gb hyperx 1866mhz

Cpu: amd fx6300

Mobo: gigabyte 78lmt s2 r2 (bought in 2018)

 

 

 

Sorry if there is any mistakes in typing, i have written all this on pastebin and tweeted it to jayztwocents and linus and Anthony, upon which Anthony has replied to me: " After those steps, my gut says CPU/RAM; I've found FX CPUs' IMCs degrade over time. Try a BIOS reset and upping CPU NB and DDR3 voltages slightly (start with ~0.05-0.1V). Leave RAM speed at default.

 

Disclaimer: This will degrade it faster. There's no fix if this is the issue. "

This seems like it is more than a problem with your computer since other tech has been damaged during this time. It sounds like you're getting dirty power so before you get more parts to be burned  by the base problem you should have some testing done by your power company and get a solid, industrial grade, protection on your computer in the form of a surge protector or battery+surge protector combo.

a way to find if cpu stability is an issue is to downclock the cpu and look for any problems, if it works fine when downclocked then you should probably replace it as its on its way out
