Windows 10: IntelR Pcie controller x16-1901 code 10

Need help, my NVIDIA gtx 1650 is not detected in device manager because of IntelR Pcie controller x16-1901 code 10. My device is HP Pavillion gaming Dk-0042tx, OS windows 10 home. Thank You

Intel (R) PCIe (x16) - 1901 keeps malfunctioning

Hello. This happened to me while i was in a Dota 2 match. The game crashed - leading to pc crash. Since then, i was facing DXGKRNL Fatal error and DPC-Warchdog-Violation.

1- I did system reset (kept files)

2- I did window again (deleted everything)

3- I downgraded to windows 10

4- i re updates to windows 11

But nothing worked. After four days, i realized that this driver Intel (R) CPEi (x16) - 1901 prevents my Nvidia Gtx 1650ti from starting during the game, which leads to crash.

Even if the driver is installed properly. During the game, it malfunctions and yellow exclamation mark appears before the driver. Any solution would be welcomed.

 

Using a PCIe x1 card in a PCIe x16 slot


Here is something I recently found out. I have tired this and it works.

You can use a PCIe x1 card, or a PCIe x4 card in a PCIe x16 slot. They work fine. So if you think you are short of PCI-e slots, you may not be. A shorter PCIe card works fine in a longer slot.

On PCIe X1, X4 and X16 slots, the first 18 pins are all wired the same, so as long as the PCI-Express card fits in the PCI-Express slot, it should work.

This is not the case for the legacy PCI (32-bit, non-express) slots, that are not PCI-Express. Those are not compatable with PCIe cards.




Picture of assorted PCIe and PCI slots.

The top four slots, in the picture above, are, from the top to bottom,
PCIe x4 slot , PCIe x16 slot, PCIe x1 slot and another PCIe x16 slot. A PCIe card that can physically fit in any of these slots will work, even if it doesn't fill the entire slot.

The bottom, 5th slot, is a PCI legacy (32-bit) slot. PCIe (express) cards will not work in this slot. It only accepts legacy PCI cards.

Here is the PCI-Express page on Wikipedia showing pinouts, etc.
