Heya! i just installed a Ryzen 9 5950x going from a 5600x, the bios asked me for a ftpm reset, wich i did, but now everytime i boot up the pc and go to mint from the Grub, there's no displays and my GPU goes bonkers (fans turns really fast and loud) and i have to hard reset the PC.
if i launch my windows 10 from Grub (dual boot), it works fine and sees the new CPU correctly.
I'm not sure what i need to do here, thank you.
I also looked online for solutions but i couldn't find anything linux specific
flint wigeon
I also tried booting into recovery mode but there's still no signal, this time the gpu is silent
trim adder
turn off secure boot
then set your BIOS BOOT ORDER properly
if a new system, make sure the computer boots linux mint from the UEFI loader (named ubuntu) and not the legacy loader which is the model name of the SSD or hard drive.
flint wigeon
It's my old system, i only changed the CPU, heres some photos of the bios settings
It's put on "other os" right now, and the keys tab looks like this
weirdly enough secure boot status says 'setup" and not enabled or disabled
trim adder
see if u can boot a live distro
flint wigeon
Like on Ventoy/Usb?
alright
gonna try xcfe
oh wait no cinnamon
Okay, started Cinnamon from the live USB, same problem, gpu fans going loud and no display
i'm gonna try xcfe now
Yep, same thing
I figured Linux mint wouldnt give me trouble for swapping cpus on the same board but i guess it does
If anything , my MOBO is asus tuf gaming plus wifi, and i updated the bios recently too
trim adder
maybe the CPU is too new or something
is there an Nvidia graphics card involved here?
flint wigeon
Yeah my gpu is a Rtx 5070 Ti, it's quite new, but it did work fine with the previous cpu
could it be a gpu issue?
flint wigeon
Alright, i'll download the iso rn on the windows boot and put it on the usb
trim adder
and live boot it in both normal AND 'compatibility' mode in case normal doesnt go
flint wigeon
Gotcha
trim adder
make sure to let the usb flash rest a half minute
after ISO supposedly is "finished" copying over
flint wigeon
noted
oh also the cpu i got is from 2020, for the am4 platform, i didn't switch to am5 yet
Mint 22.2 (non compatibility mode), same problem, going to try compability mode
Same thing happens as when i tried compability mode on my grub, No display, but this time the gpu doesnt freak the fuck out
i used 22.2 cinnamon, that's fine right?
oh wait what, i let it run for longer than usual, the gpu started running loudly, theres no display but i HEARD the linux Mint sound that plays on boot
(on 22.2 compability mode)
i got this installed on my computer rn
(the live usb had 22.1 because i didnt update it in a while iso wise)
trim adder
i used 22.2 cinnamon, that's fine right?
yes
trim adder
oh wait what, i let it run for longer than usual, the gpu started running loudly...
right, so a live boot off USB usually takes about a minute and 45 seconds to 2 minutes to reach desktop.
Did yours reach a viewable live desktop?
flint wigeon
nope
trim adder
damn!
flint wigeon
i'll try again and wait longer
flint wigeon
i waited like 5 minutes with a jingle on the compability one for 22.2
trim adder
if u ran the live 22.2 - in compatibility mode - there should be no reason for it to NOT reach a viewable live desktop
unless ur GPU is messed up or something loose.
perhaps a DC power feed
got forgotten.
flint wigeon
Windows 10 does boot up and it works fine so that's even more puzzling to me
both my os are installed on NVME's
trim adder
does ur mobo have onboard graphics?
flint wigeon
The cpu doesn't
trim adder
in which case, a VGA, DVI, HDMI, or DP port will be there. farther away from the nvidia bracket
flint wigeon
nor did my old one
oh lemme check for that then
my mobo has a hdmi and a displayport
trim adder
idk if ur newest CPU has an integrated graphics processor
flint wigeon
it doesn't
trim adder
or in ancient times, dedicated microchips (ATI , for example - now known as AMD) would be soldered to the motherboard
flint wigeon
Btw launching Ubuntu does the same thing
trim adder
ikd
run Windows, use CPU-Z from cpuid.com to screenshot info on the motherboard, the CPU, and any/all GPU and post here.
flint wigeon
i waited about a minute, just heard the ubuntu jingle, but no signal
alright will do
trim adder
check BIOS and disable any onboard graphics support
to forcefully route video onto the dedicated nvidia GPU
at least for linux to do so
flint wigeon
Here's the CPUZ result, and gpuz too as bonus
trim adder
according to this, the CPU works well for linux.
do powercfg /a in Windows terminal please, and show result @flint wigeon
also show the mainboard tab of CPUZ
flint wigeon
on it
the cmd result is in french so lemme translate it rq
it says S3 is available, long sleep is available and hybrid is available, Microprogram doesn't handle S1, S2 and S0, and fast boot (the windows one) is disabled
flint wigeon
The last one, 'démarrage rapide' means fast boot, some days ago i disabled it on windows because it was giving me trouble on linux with my HDD's
flint wigeon
my HDD were read only when that was enabled for some reasons
trim adder
it causes many other issues too
flint wigeon
(i use 2 hdd on windows and linux in tandem)
cpu-z wise, yeah i updated my mobo in 2025, and looking at the fabricator list, the cpu is supported too
trim adder
anyway, idk what to tell u further.
flint wigeon
oh dear
trim adder
mint 22.2 should boot live within under 2 minutes
check all connections
and all bios. consult a technical manual for ur bios
perhaps has some info to be followed
flint wigeon
i was thinking maybe my nvme got disconnected or something but if that was the case it would work with the live usb
I tried 22.2 again, non compatibility mode, heard the jingle but no display yeah
should i enable csm?
i saw that option in the bios earlier
it's disabled right now
trim adder
that's the legacy live menu
flint wigeon
ah huh it selected the first option automatically, bunch of things appeared, some terminal lines, some glitched image, and now its back at a no display and fast gpu, i heard the jingle too
trim adder
k try the compat mode
lastly try a different discreet GPU if u have one (non-nvidia)
if it works on that, then it's definitely nothing to do with the CPU upgrade
flint wigeon
i have a rtx 3070, the other gpus i got are like, super old, i guess they can work?
trim adder
yes super old will work on the free driver
flint wigeon
found this
this one has hdmi nice
I just found out the psu to cpu cable wasnt 'clipsed" or at least looked a bit like it wasnt all the way in
before changing gpu, im gonna boot and see just in case
trim adder
aight
trim adder
perhaps a DC power feed
.
flint wigeon
welp, it boots
low resolution but it boots normally
The gpu inside rn is a Geforce 9600 GT
i mean, i guess i can try with my rtx 3070 too??
i had that one before the 5070 ti, with my old cpu too
My guess is i could try to download a previous Nvidia driver from there? it doesn't really make sense but i don't have a lot of guesses right now
i got kernel 6.14.0-33 generic
one thing i didnt do is try the hdmi on the 5070 ti either, i only tried displayport, dunno if that would change anything but yeah
i do have access to my Linux install right now so if you got ideas on stuff/commands to run lemme know
trim adder
i do have access to my Linux install right now so if you got ideas on stuff/comm...
if your install boots fine, then it's not the CPU change
it was either bad PCI slot insertion, or loose DC cable on the 5000-series GPU
flint wigeon
I'll try plugging it again
I put it back, the same problem happens again, yet it works perfectly fine on windows
I'm sure the GPU is slotted in correctly as well
hell i'm gonna boot up cyberpunk for a bit on windows and check performances
trim adder
There's also Tuxedo OS, which offers some kind of nvidia bootmode
runs KDE Plasma desktop, wayland graphics platform
and Zorin OS, which i believe has an nvidia liveboot mode
dont forget to disable Legacy bios boot
flint wigeon
alright, i'll download these Iso's
I don't know any of those tho so yeah
Okay so before that, as a test, on windows im on cyberpunk, 1440 p, ultra ray tracing, literally 0 frame drops and smooth fps
so at least i know the hardware works fine
trim adder
ok
flint wigeon
i'm gonna try tuxedo os first
Do... i try the fallback one?
damnit, the fallback does the same thing
flint wigeon
i figured i'd try lol, trying the first one rn
Could the problem be that secure boot says setup instead of disabled perhaps? also I tried the live version right now and sadly same problem again
trim adder
i figured i'd try lol, trying the first one rn
setup mode should be fine
before you changed the CPU, was Mint very difficult to setup the 5000 series nvidia?
flint wigeon
Nope, i installed mint back when i had the 3070 in like a year ago iirc, then recently changed to the new one, slotted it in, worked fine out the box
flint wigeon
It wasn't today, it was a few months ago
like, at least 5+ months ago
wait huh?
HUH?????
Okay, i tried some stuff and
In the bios, i resetted everything back to default, that didnt work, but then i tried that "resize bar" thing, i tried turning it on earlier but it didnt seem to have worked, but this time i turned it to on and directly saved, it told me 'save these changes' wich were something about 'above 4g' and 'resize bar: auto'
And it booted??!?!?!? im on my mint install right now
That's, random, i could swear i had tried earlier too but now it works so yay
