HELP NEEDED - GPU fan spinning but no display on monitor
Written by: masWiK - 13:04 Feb-23-2016

Hi guys I need some help here, I know maybe it's better to shout this but I've done that and it was not really effective. My GPU isn't displaying any pic on my monitor even though my GPU fan is spinning.

I'm using DVI to VGA adapter and my monitor keep showing "no signal" notification, and I've tried to use the HDMI to VGA adapter but I got blank screen (just plain black) and my monitor light is on and off repeatedly, without "no signal" notification.

Currently I'm using the iGPU and when I open MSI afterburner, it doesn't show my GPU name (HD 7800 series). My GPU driver keep not responding a minute after I boot up my PC, and I got this notif

I've tried to switch my primary graphics from auto to PCIe in my BIOS but when I reboot my PC, it changes back to auto again. And I've tried to re-install my GPU driver but the driver installer doesn't give me option to install the driver (probably because my PC doesn't recognize my GPU). But I haven't tried to unplug and re-plug my GPU.

So is my GPU dead? or can I do something else to make it work again, so please if anyone can help me it would be much appreciated.

Well guys, bad news. Finally I got some free time to open up my PC, I've cleaned my PC, pull out my GPU, clean it but I havent put off the cooler, put it back and make sure it's attached nicely, even using another cable from my PSU, but still it just didnt display any picture :( Well I think my GPU has passed away.... Probably I'll make another blog about my dead GPU cuz I'll open the cooler. Btw thank you so much for the help, it just my GPU that doesnt work anymore :'(

By what you are saying, there are 2 possibilities. The first one is that you have a dead graphics card, which isn't that bad since there are things you can do, like put it in the oven (look it up, i am not crazy!!) and try to fix it or get a new one. The other possibility is that the DVI connector is defective, which means that the gfx is probably fine, but you have to use another connector like HDMI or displayport. In any case, you can try to clean your gfx from dust

I once had a pc that wasnt even posting and it was due to dust shorting out the circuits on the motherboard, and the pc worked fine after i cleaned it. Maybe that's what's going on with yor gfx, try to clean it, it's very very important.

Make sure your monitor is set up to receive the correct display type, if i set mine to analog it does not display my desktop, however if i manually set it to digital/HDMI it works fine. Is your GPU fan spinning at 100%? If it displays something while booting, then its a problem elsewhere, i would try different cables if you have any, maybe a friends pc, maybe take out your gpu, boot your pc using onboard, turn off the pc, then plug it back in making sure its in properly with the right power cables. I hope you come right and it did not die

I've tried to look at my monitor setup menu and I dont get the option to set display receiver (analog or digital), maybe because the input is only VGA.
This is my picture of SpeedFan (http://i.imgur.com/vEmtqo5.png), sorry cant make the link here (somehow it doesnt work lol). I'm not sure what are those things mean, so I just give you the picture.
I'll try to unplug my GPU later, like weekend if I have to deal with the hardware. Do you mean different cables from PSU to the GPU right? Well maybe I've to try it.
Yes, I hope it doesnt die :( thanks for the support bud

Yeah, i think speedfan was all your cpu info XD Yeah, try different cables, make sure the gpu is clean etc. I know how it feels, "pls don't be dead, pls don't be dead, i'll try anything, pls don't die". Try what you can. I'll keep my fingers crossed for you

:D I'll be so screwed if my GPU end up dead, its like the most expensive thing in my PC. And I plan to upgrade it like 2 or 3 more years, so... yeah :(
Okay appreciate it bro, cheers

Wow, that motherboard can't be that bad, SpeedFan isn't either! A lesson: to gain the best readings, you must take care you've got the latest chipset driver. Why? Chipset > Southbridge > Super I/O = partially the 'department' from where sensoric informatio is delivered.
You can also check the name of your Super I/O chip above the readings, in the text block within SpeedFan. It looks like this: "SuperIO Chip=Winbond W83627DHG-P"


It makes sense to say (due to your quad core), that those 'AUXTIN' temps refer to your CPU core temperatures, but without a doubt, no temp is correct. Your CPU surface temp = 35C, motherboard = 31C, HD = 32C, the others could refer to the ambient temp and your 'unkown' GPU temp...

my Super I/O is "SuperIO Chip=Nuvoton NCT6779D", so I should download the driver by searching my Super I/O name on google?

As for your iGPU = HD 2000 graphics: there is OpenGL 3.1 support, so maybe you should update the HD driver?


As for your main problem:



  • You have been using those adapters a longer time already? I once read about passive & active adapters and that passive adapters seem to be BS...I don't need it, so never really examined it any further.

  • It makes sense that you don't see much/anything in MSI Afterburner, but when running a prog like SpeedFan, maybe you see an (undefined) temp + fan speed RPM there? Sensor information might still be collected...

  • Did you run the Crimson/CCC utility to properly remove the driver and then reinstall? I've gratefully used Display Driver Uninstaller (formerly known as Driver Sweeper) in the past, for example when upgrading to another graphics card, not wanting any leftovers. A tool like this goes further than just deinstalling and running a registry scan!

  • Is there maybe anything useful you can view via your Windows Logs? Type 'logs' (in your language) via 'Start' > Windows Logs > 'System'...and maybe 'Application' > Sort by date.


As Tzzsmk said below: best would be to test it another system ;)

Oh so the notif that I showed up there is to update my iGPU driver? Alright, never use the iGPU since I have this PC lol.
This is the picture (http://i.imgur.com/vEmtqo5.png) of the SpeedFan that you recommended.
I use Display Diver Uninstaller, and I usually delete all files that named "AMD" before installing new driver. But when I re-installed the driver days ago (after my GPU dont diplay pic), it didnt show AMD driver to be installed (maybe my PC dont identify my GPU)

Well, not directly, but it makes perfect sense to say it's outdated/factory due to the fact there's a driver that supports OpenGL 3.1 and yours doesn't even seem to support OpenGL 2.0 :P
But yeah, this is not where this case is about ;)
I responded on those SpeedFan temps above ;)

I dont think there are any massive problem related to my GPU doesnt display any pic in the windows log, just some errors and warnings that I already got even before I booted my PC and discover that my GPU didnt show any pic

If you say so ;) If you're doubting, you can always save a Windows Log and send it to me :) Of course deleting it first and running the system a few days, to avoid the mess.

it depends on which DVI do you plug VGA to, nowadays there are usually 2 types of DVI,
DVI-D is digital only and cannot be used for VGA
DVI-I offers both analog and digital, and can be used for VGA

Well yeah, I've been using the VGA to DVI adapter since the first time I use my GPU, and I just come to this problem some days ago. But a day before my GPU can't display a pic, my PC just run fine

hmmm, do you even see anything on screen during boot? if yes then you could try booting some linux to justify there isn't a problem with Windows drivers...

No as far as I know, just straight up no signal with DVI to VGA and just blank screen with HDMI to VGA. I've tried to restore my PC as well but it didn't solve the problem

then probably the gpu is dead, if you could try in different PC, it would show if problem really is gpu...

I think I had a similar situation, Sapphire 7870. In my case, I'm not sure if it is because I blew the dust on the fan using a bicycle pump a few days earlier or because it is more than 2 years old. Anyway, I baked it in oven with no success. Now I'm using a 6870 which I've bake twice (before I bought that 7870).

So you are currently using HD 6870 that you've baked it twice? Damn, I dont have balls to do that with my GPU. My GPU is like 3 years old, I expect it will last for 5 years or so, and I dont have any idea about cleaning with bicycle pump related to GPU dead. I mean Sapphire GPU should be okay for more than 5 years imo, its a good brand. But thanks for sharing dude :)

Never underestimate what moisture and static electricity can do to your PC. As for moisture, I think a bicycle pump can be considered okay, but never work in humid areas ;)

I mean, they say that air blower can generate static electricity which can damage compononents, so I think maybe pump can do the same.

But only in case of contact with another, different material, so that static charge can build up. Same with a vacuum cleaner, but with that device, avoid spinning fans as well ;)

yeah, it looks like though baking (or another way heat gun) cannot fix broken capacitors, VRM, and GPU. It only deals with circuit reflow or something. I assume your warranty is over right. For your case, maybe you can ask someone to check for broken caps or something like that. capacitors can be replaced.

You can also hook up your card to whatever display device that makes use of HDMI connection, to rule out maybe the dvi interface.
