Did you restart your pc as it suggests ?
it happened yesterday
so i alr shutdown my pc
:val_SusgeNoted: so you didn’t restart and try
today i queue again and it happened again
so i need to try restart?
cz i thought if shutdown didnt work then restart must have not too
Did you add/remove PCIE devices ?

@ItsGamerDoc IOMMU :Clove_Wave:
I tried to go into my bios and try to enable IOMMU but i cant find on my bios
Ive look everywhere to enable it but i cant find it
What mobo you got
My motherboard is Asrock B650m pro rs wifi
And Im using Amd cpu
Everyone said i need to go to advanced > amd cbs > nbio something
But i cant find this nbio thingy
:val_SusgeNoted:
im so tiredd T_T
I think i might have fixed it
What did you do :val_SusgeNoted:
so basically
i did smthg stupid
LOL
:val_HUH:
i didnt know i supposed to click enter on my keyboard in bios
I click right arrow
LOL
thats why i cant find IOMMU in my bios
:val_PepeLaughPoint:
omg
now im trying
just give me a few minutes
ill let u know
@Rachel
It did not work
i enabled Iommu alr
you keep get the pop up already ?
yup
this thing basically fucked my pc so bad
everytime i launched val my windows keep getting the "update and restart/shutdown" and my pc got tossed into "windows automatic repair" loop
this happens if i launched val, if i didnt launch it, my pc wont get the "update and restart/shutdown"
so i can conclude that the val is broken not my operating system/pc
what windows you have ? and do you have any PCIE plugged in ?
win 11 and I do not have any PCIE plugged in other than gpu
sound card for example or any kind of PCIE other than gpu
nope
so everytime you try to play you got this pop up
do you crash or it just ask you to restart ?
yea not instantly crashed
but like after a few min in the game
basically this popped up

when i clicked ok
val closes and a microsoft edge web popped up about the things i need to enable
so i followed it and it didnt work
but you have them enabled ?
all of them except the IOMMU
the IOMMU was on auto
i changed to enable
okay
mind showing device manager network adapter ?
alr wait

are you on ethernet or wifi ?
also can you show the ports
im on LAN rn

cable you mean
yea
okay
im using lan cable
disable wifi adapter
and what those for ? what you connect w them ?
im not really sure what are those
alr
you gotta wait for now
yup
im planning to reinstall val
i think riot didnt detect that i alr enabled the IOMMU
will not help
welp
its anticheat related
:((
okie then ill play with my laptop for now
you have to wait for gamerdoc to check what is the issue and solve it if he canll
Solution
download this

the driver u have for ur wifi device is incompat with dma remapping
thats why you are having issues
Alr so i need to download the one that u block it?
no just download it and right click on your wifi adapter
update driver
let me pick from my pc
and select the folder
Oh ok
Thanks
Do i need to restart my pc afterwards?
Or i should be fine w/o it?
give it restart wont hurt
I can try it now
I have a few hours
Ill give it a go
alr

so i click the realtek one right?
no
no
just install
the driver
thats it
did u download it and do what i asked?
oh ok
yup
kk go play then
should prompt u again since it needs to re-apply the iommu logic
and then u shouldent have any bsods anymore
oo thats why it causes me bsod
:val_CatJam:
ok i just installed it
start the game iommu will pop up once more
and just got gave it a restart since valo said i need to restart
restart then you should be fine
open val first
After installing it, I cant launch it
idk why
it says neeed a restart
but im launching it now after that restart
yea
so it will pop once after this?
yes
when you start game it will pop up restart then you are good to go
yup it just popped
restart
I hope this works
do you have doubts in gamerdoc ?
thats criminal
NAH
i dont
xD
he will put you in loser Q
you not gonna gain rr for the next 10 days
pls no :val_Hampter:
so basically this problem caused by non updated wifi adapters?
so if in the future my friend have this problem too, its because of a non update mobo driver?
not all the time and not all the same
its diffrent
but if they got problem they can come here and will help
cz at first I didnt know that val global dc had this community help
so I search for a case in Valorant Indonesia Community
so many case happened
no solutions
i even contacted a few of them to ask bout the solution
but they cant do anything so they dont play val anymore
since i know u guys can fix it, im going to redirect them to u guys
sure always
so how its going now ?
its been going for more than 3 minutes
no crashes so far
its 5 minutes
no crash then you are good to go
aight
i will let u guys know
yea i think max 10m if no crash then the goat handle it good
yea i might go for a tdm q :val_Prayge:
go ahead
and btw can i delete the drivers file?
folder*
yes you dont need it anymore
aight
@ItsGamerDoc @momo I think its fixed
thank you guys so much for your helps
:val_Prayge:
no problemo
have fun
I will ;D
enjoy kings
