pc stops responding

[marcuzx]

alright so 3900x is the cpu, running a 3090 and a 3080 on this pc

 

 when let’s say I open 40 runescape clients the mouse laggs, computer starts freezing and then even tho I’m using my 3090 the fans on my 3080 start spinning and I lose signal to the display 

 

recently same thing happens if I start mining as well

 

it only happens when gpu is under heavy load. I tried the same with my 6600xt and yea the computer is extremely laggy with 40 clients open but it doesn’t crash

 

prev the 3090 was stable even with 100 of them open although it was at 100% load consuming like 400 watts or so. my 3900x was at like 97% load

 

I think the issue also gets worse with cpu is over 50% load but not really sure. all this sht started happening after a windows update recently 

 

this is kinda disappointing because my dualcore and 9600gt or 9800gtdidn’t even have such issues, they just didn’t wanna open sht and we’re just laggy

 

I wonder what causes display to stop working and for a gpu which I’m not even using to start spinning its fans

You should be able to rollback your windows update if you think that is your issue.

idk how to rollback but this is so strange? let’s say I click to open 40 clients. mouse will start glitching, itll be extremely slow and then display turns off. I was monitoring gpu wattage and it was anywhere from 150 to about 300. 

 

as for cpu voltage it goes to 1.4-1.5 cpu usage varies from 15-55 which is quite strange 

 

the gpu usage is at 50 to about 90

 

ram usage is 50%
 

gpu temps are around 60 which is quite normal, like 70 ram temps

 

cpu is kinda strange ranging from 45 to about 65 degrees like wtf

 

I am using a 750 superflower argb psu which has been mining flawlessly for like a year now. my 3080 and 6600xt have one 750 watt psu while my 3900x and 3090 have a separate 750 watt psu

 

hdd usage is 81%
 

3090 voltage is .65 lowest, .7250 at idle and highest is 1.0810v

[marcuzx]

bro im starting to think hdd is fucked? 

[marcuzx]

my 3080 has exact same issue as the 3090 so it’s definitely not gpu issue 

[marcuzx]

whenever gpu draws alotta wattage pc freezes and then displays disappears

[marcuzx]

oh and fyi in this specific room pc has turned off whenever ac turns on so the room is notorious for electric issues 

 

it may be that its electrical issue as I had before 

 

of course I called the electric company and they said the problem was inside the house. that’s what happens when you have bootleg electricians do work in ur house ffs

 

 so now idk if it’s hardware related or if electricity related 

[marcuzx]

 tried different outlet. with 3090 it opens a few more clients but mouse starts freezing again

 

I did manage to get 78% ram usage out of 64gb wow! ofcourse on the 6600xt cuz both 3080 and 3090 crash the pc

 

I think the problem is definitely voltage/wattage due to bootleg electricians which did the outlets

 

if I take it slow I’m able to not have the pc shut off but if I’m a bit more aggressive it turns off I think due to insufficient voltage or wattage. 

[marcuzx]

rofl 6600xt also crashed it eventually 

[marcuzx]

it’s also not the gpu which is turning it off but I found out once turbo turns on it turns off the display. so high cpu usage/frequency turns off the pc

Sounds like a classic like borked PSU issue OR its a faulty temp sensors. Its one or the other.
