Question Need some advice - My new Mobo doesn't recognize my GPU

So I have a somewhat old PC that I decided to upgrade. A friend of mine got me some parts and I replaced my old Core2Quad Q8400 + Intel DG41RQ Mobo + 4GB DDR2 for an i5 2400 + Intel DH67BL Mobo + 8 GB DDR3.
To upgrade I simply replaced the mobo with CPU and mem inside my case, plugged the GPU, SSD and done. The problem is that this board doesn't detect my GPU an EVGA GTX 460. It's not even listed as a PCIe device.
Windows Device Manager also doesn't show the GTX as a video device. Integrated Graphics works fine.

So far I've tried:
  • Upgraded the BIOS to the latest version (0162)
  • Reseated and cleaned the PCI lane twice
  • Disabled UEFI Boot
The "Video" config options on the BIOS is set to Auto, but changing any value here didn't produce any result.
Could it be that this "new" mobo has a faulty PCIe? A have an old PCIe that I'm gonna try next, when I get home from work. I know it's not my GPU since it's working fine on my other mobo.
Any other ideas to try?

Thanks

You're advised to reinstall the OS when you replace the motherboard, so that's where you should start first. Also, manually install all drivers relevant to your motherboard after downloading them manually from Intel's support site.

Make and model of your PSU and it's age?

I'm planning on reinstalling the OS of I keep this system. If I don't solve this issue I may go back to the old one.

I have a Cooler Master 460W (will check the model when I get home) and it's like 11 years old. Could it be the PSU even if it works just fine on the other system? There's a brand new one coming for my other build this week. I can try and test this.

But the BIOS itself doesn't find the GPU.

Could this be anything to do with an UEFI mobo and a non UEFI GPU?

I don't think its your PSU since it works fine on you old config the TDP on your i5 2400 is the same as the core de quad q8400 at 95w and your using the same peripherals , I think your PCIe slot may be faulty to make sure try using a different GPU if it doesn't work try cleaning the slot with Isopropyl alcohol if it happens to be faulty you can get a cheap Chinese H61 board for around 25$, I have been using one for about a year now with my 2500k and its working just fine.

by the way does your dedicated GPU (460gtx) posts anything pre-windows when you boot your pc on, if it does it's probably an OS problem reinstall windows and you be fine, if it doesn't well like I said before its probably your PCIe slot.
