GPU not working after CPU swap

[BTyler0921]

I need help everybody. I have an old HP Z210 CMT workstation I converted into a budget gaming rig. It had a Core I5 2500 in it. My graphics card is an NVIDIA Quadro 2200. It was working great. I played the Outer Worlds on it Tuesday night with no issues. I moved it to a different location Wednesday and setup dual monitors on it but again the system was running fine and graphics card was functioning as it should. Well yesterday I got the new (to me) CPU I was hoping to upgrade too, a I7 2600K. I threw that in it and reapplied thermal paste, etc. When I plugged it back in I got the sound Windows makes when it first boots up. But had no display from my graphics card. I plugged it in via the onboard graphics and it works just fine. New CPU is recognized in windows and in BIOS but I cannot get the graphics card to work. The only setting I originally changed in BIOS was to enable Hyperthreading. I verified the card didn't get fried by testing it in another system. The card has power to it because the fan runs. But I have no display. Do I have a bad/failing PCIE slot or is this settings related in BIOS? Would having Hyperthreading enabled cause the card to not work? I am stuck y'all. I don't want to be stuck using onboard graphics

Did you reset CMOS and check in BIOS the primary display?

have you tried a different slot?

Well this is super old hardware and i’m not super familiar with it ,but maybe you need to check Bios if there is an option to choose your primary GPU. Your system might be using iGPU instead of dedicated GPU.

I tried the other PCIE x16 slot and my computer kept making this obnoxious honking/beeping noise. It doesn't do that if I plug it in the primary slot which is slot 2 on this motherboard. Pcie slot 1 is the x8 slot.

I don't see an option to disable that the only potentially related options I see are igd memory, PCI serial bus frequency or whatever delay. When I first installed the card it didn't work either and the igd memory was set to 64 MB and I changed it to like 128 or whatever the setting is and that made it work but I have already tried that again and it is not working it goes all the way up to like 512 and I have played with most all of the settings and it doesn't seem to make a difference. I have not taken out the CMOS battery yet I wasn't sure how to do that but I did just watch a video on it so I will try that when I get home

I will admit my power supply may be starting to fail so that may be part of it I do have to power cycle the computer for several times to even get it to turn on. Once it turns on it'll run just fine without the graphics card. I can have the graphics card plugged in and plug into the integrated ports and that will work. I was wondering if it was because this CPU was somehow drawing more power but according to the Intel website they are both a TDP or whatever the setting is of 95 w

do you still have your old CPU? what happens if you swap it back, does the GPU start outputting again?

I go to like integrated devices or whatever in the bios to search for the graphics card because I had seen that as a possible option but nothing shows up there but it didn't before when it was working either. I have reset the defaults several times in the bios so I'm trying to restore the settings to what they were before the CPU swap but originally the only thing different was hyper threading being enabled. I thought maybe just the GPU and the CPU weren't compatible somehow but I tried an old GTX 730 I have in my old Dell system and that card didn't work either. I go into the Device Manager in Windows and even though the GPU is plugged in it doesn't show up there. There's an option for PCI but when I click on that it says it has no drivers installed and can't find any on Windows update or by automatically searching for them I have uninstalled and reinstalled that PCI option and that didn't help. Do I need to try to do a system restore to a few days ago if I have a restore point and see if that helps?

I do still have the old CPU I'm planning to swap it back when I get home from work today and see if that helps and I will post an update if that somehow works

[BTyler0921]

Swapped the CPU back and it fired right up. Full audio and video from the graphics card. Thanks everyone for helping. Guess that CPU is going back to the seller. Not sure if it was incompatible between the Graphics Card and CPU or what the issue was but it seems to be fixed now.
