Desk will not power-up after adding NIC PCI-e card

[BobE1]

Attempted to install Intel EXPI9301CT nic card.  After install, desktop will not powerup (power supply solid green), everything else seems dead.

Removed the card and placed it in another PCIe slot with same result. 

Removed the network card and now the desktop powers up normally.

Bad card??? or something I neglected to do before installing?

The original NIC is integrated with the mother board, but is limited to 100 MBPS. 

The after market card is 10/100/1000. My ISP service is ~ 250 Mbps

@BobE1,

Welcome to the HP Support Community!

I checked the specifications of your computer and see that the NIC card on the computer does support up to 1000Mb/s. Refer to the below link for the specifications.

As you have mentioned that the computer doesn’t boot after installing the aftermarket NIC card it confirms that it is not supported on your computer.

Hope that answers your question and you have a great day!

If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!

Greetings,

Welcome to the forum.

I am not a HP employee.

I don't know, this Intel NIC should work as it is a PCIe x1 device.

Check BIOS slot security to verify the x1 slots are active.

The onboard NIC does not support 1000 Mbps but a add-in NIC should deliver the speed.

You have no USB 3.0 ports so a USB 3.0 WIFI dongle will not help.

This PC is about 10 years old. You may be out of luck.

Yes, I check the product specs as well and it does indicate data transfer rate of 10/100/1000  with a Lan Gigabit 10-base-GT -ethernet. If I can get that to work that would be wonderful.  As it is built on the motherboard the only thing I have to play with is the network adaptor that appears in Device Manager.  Apparently that adaptor is a Realtek PCIe GBE Family Controller.  

(That is called a PCIe is a bit confusing because there is no ethernet adaptor in any of the PCI slots.)

Anyway, From Device Manager, I opened this Realtek PCIe GBE Family Controller, and device manager reports that it is working correctly. Next I looked at the driver, the driver is dated 13 July 2009 version 7.4.713.2009.  So I looked to find a updated driver, Device manager reported that this driver is the most recent!

I am at a loss to know what to do next to get this ethernet connection to transfer the 250 Mbps I'm paying for from my ISP.

(BTW, I said that the computer would not power up....no lights, no fan, no nothing.   However If I can get the onboard NIC functioning I don't even have to deal with the Intel PCI e card )

The PCIe slots are active, as I removed a Firewire adapter and it ran without difficulties.  

The specs on the computer (as manufactured) suggest that the motherboard provides a LAN Gigabit 10-base-GT  ethernet  that provides 10/100/1000 Mbps --- but I've not been able to get it to work.

Hi,

The onboard   Realtek 8111DL supports:

• Data transfer speeds: up to 10/100/1000 Mb/s
• Transmission standards: Gigabit 10-Base-GT Ethernet

I have no idea why you can't get close to 250 mbps downstream. I also don't know why the Intel PCIe NIC locks up your PC.

Very strange. Again, your PC is about 10 years old.

Just a thought: Do you suppose the desktop will not power up because of a conflict with the on-board nic and the Nic being added to the PCIe slot?

 If so, does that suggest disabling the on-board NIC  (via BIOS ???),  then shut down, install the NIC card one of the PCIe slots and try to power up ??? 

Can I disable the on-board NIC from device manager or would that only disable it for that session (that is, would be reenabled upon being powered up again)

Hi BobE1,

On board NIC BIOS status could cause a problem if the device is failing or there is a interrupt request conflict with a second NIC.  Any boot issue is possible when an incompatible device is installed in the motherboard.

Check this BIOS setting site by HP (Link). Look in Security Menu, Device Security for disabling the on board NIC. Your BIOS version is very old. The setting to disable the on board NIC on your PC's BIOS could be anywhere if it is even available.

Again, your PC is about 10 years old.

Disabling the NIC in Device Manager may not fix a boot problem. Windows will install the NIC driver if this device is active in the BIOS settings. Disable on board NIC in the BIOS. No need to mess with Windows Device Manager. 

I still don't know why you can't get close to 250 Mbps using the integrated Realtek NIC since it supports 1000 Mbps.
