Dear Captains,

 

I'm here again, please help me. I just changed my i3-3220 processor (dual core) to an i5-2400 (quad core). I installed a fresh OS, windows 10 64-bit, HOWEVER, my less than two months old GPU can't be detected :( WHY ???

 

 

Things that I tried doing:

-Freshly installed OS

-driver installation -> BUT SAYS THE WIZARD CAN'T FIND ANY NVIDIA GRAPHICS CARD 

-Plug & unplug, making sure it's correctly and well-seated on its place

-CPU has normal temperature, 35-38 for all cores...

 

Please help!

This worked for me:

Here are the steps I tried to fix the issue on my computer.

1. Turn off the computer and unplug
2. Remove Graphic card
3. Plug the monitor to your video output
4. Turn on the computer
5. Click on start and type msconfig
6. Select the Boot tab and click on the box that says Safe boot with minimal selected. 
7. Apply then click ok.
8. DO NOT RESTART.
9. Shut Down computer and unplug
10. Install Graphic card
11. Turn on the computer (should boot into safe mode)
12. Go into Device Manager
13. Expand Display Adapter
14. Disable the Intel(R) HD Graphics 4000 driver. (DO NOT UNINSTALL)
15. Click the start button and type msconfig
16. Unclick Safe boot
17. Restart

The computer will restart normally and will no longer get the black screen. See if that works for you. I didn't mess with any setting in the bios. I am assuming that having two graphic driver install don't like to play well with each other :)

I'll try this one right now, thanks! Hopefully would fix the problem. On-board display works fine, though... :(

Do you get any gpu visuals?

device manager detections? NONE is the GPU's fan working? YES. GPU was working fine before the changing of CPU.. I ran the CD Driver but it tells me it can't find any NVIDIA hardwares.....

When the gpu is plugged into the pci-e slot, do you get any visuals through the video passthrough on the card?

not a chance, Sir.. as if nothing is there... but when I transfer to the on-board display, works fine

OK. Just wanted to know cause if you had gpu visuals but no detection it would be a different problem. Go ahead and try the steps above and tell me what happens

Sir, after installing the card at step 10 & 11.. Should I plug my output cable to the CARD? or on to the on-board display?

mobo.  Plug into the gpu after the last restart.  If that doesn't work, do it again but at 10+11, plug into the gpu.

after disabling the on-board display via device manager, it still displays the desktop. Note that the DISPLAY cable is connected to the on-board vga.. Also, I have OTHER DEVICES THAT LACK DRIVERS: PCI Simple Communications Controller & UNKNOWN DEVICE

Did you reset your BIOS settings to default at any point during the CPU swap or the re-installation of Windows 10?  If not, you may want to try it now.  

 

You sure the power cables to the video card are plugged in all the way?  Sometimes they look like they are but they're off just enough for something to go wonky.

 

As a last resort, you could try putting the old CPU back in and see if the card works then.  Maybe the new CPU needs too much power for the power supply you have?

Tried resetting the BIOS to the default/ failsafe settings.

My GPU doesn't require any 6-pin or any cables connected to it, simply plug and play.. fans are working and I'm pretty sure it's seated correctly.

Unfortuately, I already sold my OLD CPU :(

 

I have VS450 Corsair for the power supply.

 

Previous CPU: i3-3220 

New CPU: i5-2400

 

 

I'm really frustrated :(

The desktop will still be displayed, but the igpu should be disabled.

Keep going, did you put the gpu in and start it up again after disabling safe mode?

did both, always displays from the on-board one.. sigh

So, when you do the steps above, did you put it in safe mode then disable the igpu then turn off safe mode then shut the computer off fully (not restart) then install the gpu and plug in the video to the gpu?
