Pc not turning on.

[FreelanceNewbie]

So i need some help to figure out this problem before i take any steps in purchasing a new part.

Basically computer not turning on after shutting down automatically through UPS [power outage]. I thought it was the PSU problem, but i did the paper clip test where you short it and the fan started spinning. Also, when i unplug the cpu power cable from the motherboard, a red light came on. When i plug it in again, it went off, so i took it as indication that the psu was delivering power fine. Also can a damaged cpu cause this? I do not want to take this out to check as yet.

I know that overheating can cause major damage to components, and i had one such incident after installing a RTX 3070, my pc overheated and shut down, i had since left my case opened while using it, to prevent the overheating and it worked fine after that until now. 

Right now i am thinking the motherboard got fried or something, so i would like to know any other causes or troubleshoot i can do to pinpoint the problem. (I do not have spare parts lying around i can swap in to check)

here are the specific parts if it helps:

-Gigabyte Rtx 3070

-Corsair RM 750x 

-ROG Strix B-550A Gaming motherboard

-Amd ryzen 5 5600x

You have RAM right? Have you tried doing the basic clearing CMOS and reseating (both CPU and RAMs)?

Yes i do, been using the pc for over a year now. I have not tried clearing CMOS, i will do that now.

honestly i don't know much about ups, but its apparent how many very similar cases there are and the people using a ups ... ever think that the ups maybe doesn't work as it should or is incompatible with the psu being used? as said, im not sure but that's the most likely explanation for this scenario imo.

 

also, whats the reason for using a ups? (i know in theory) but like do you have power outages often? how often, and why?

because if im honest we get power outages here sometimes... 1 in 4 years or so if i had to guess... last one, my psu and pc didn't even shut off lol (because it was a short outage*)  

Every other time my pc just shut off (cause no power,  duh) and nothing happened... so im seriously asking because this is extremely *curious*

 

as for your overheating issues,  thats also curious tbh , what case are you using? 

 

 

*that is the thing really,  a good psu already acts as a "ups" albeit only for 15 seconds or so... so this is really the question,  why add another one without checking possibly interference and compatibility issues?

 

its not even a reliable protection from what im reading

So yes, we can have frequent power outages and low voltages here, some lasting for a good time. For me the ups does help a lot when switching over to generator and the low voltages. I don’t know much about the other things like incompatibility. How do i check this?

 

I have the Musetex Atx white version case. Not great airflow, hence why i leave it open to help with cooling. Also, only 1 times i had overheating in where it just went blank and shut down, it worked back normal after that.

oh, ok i see how a ups can make sense then... its just hard to imagine for me here to have such a spotty coverage,  but again i see how it can make sense for sure...

 

yeah, as said, thats the thing, im convinced not every ups is ideal for this scenario,  but im not knowledgeable about different models and how they work etc, i was simply suggesting to look into that because i think that could be an actual solution for you.

hmm, ok, but did you check temps before it supposedly overheated, i mean even in a bad airflow case it shouldn't literally overheat...

also maybe consider undervolting, it could really help... im just thinking the side panel open isn't ideal, even though its not the worst thing either. 

 

my 3070 is undervolted,  max temp is like 73c, but *most of the time* while playing games etc, its between 50-60c honestly

 

 

Edit: i found this,  not knowing which one you actually have, i have certainly heard about the cyberpower a lot and that its supposed to actually work reliably, unlike others, so maybe this helps?

I will do some checking with the ups to see if that could have been the problem. 
 

as for overheating, normal gaming temp was like around 60-70c, but I think I was pushing the specs and fps while playing and left it in high setting then after a while , everything just went blank. The case was extremely hot to touch, I had to open it and let it cool off. Also one of my ssd started to stop reading properly and cause the pc to take 20 mins to boot. I unplugged the ssd and ran everything on my m.2 drive and it worked normal again. 
 

 

 

i have a cyber power 1500va avr

Update:

bios light flashes and comes on 

lan connection light comes on when plugged in

cpu fan light comes on when power not plugged in.

 

 

Is it the mb? Should I get a new one?

[FreelanceNewbie]

Hmmmm, now I think it’s the cpu dead.
