replaced rj45 lan input with a new lan card but runs very slowly

[p5200]

My motherboard is an Asus M3A78-EM and I have been using the system with the built in lan rated at 10/100/1000 mbps. The socket seems to be going bad so I tried replacing it with another internal card. They only had two to choose from at Office Depot were rated at 10/100/ mbps. and the other which was called D-Link DGE 530T which had the same specs as the motherboard so I got it. I've tried more than one cable and it works but is much slower did I buy the wrong thing to be running straight from a Wild Blue modem or, are there some settings that can be changed to speed it up I just run the one computer. Thanks! Newegg.com - D-Link DGE-530T Gigabit Desktop Adapter 10/ 100/ 1000Mbps PCI 1 x RJ45

Did you disable the onboard network adapter in BIOS Setup?

Try updating the drive via Device Manager, Driver tab, Update Driver then click on Search automatically for updated driver software.

I tried disabled and enabled left it enabled removed the card after removing the drivers then reinstalled the drivers first, per directions then the card again. I turned the pc back on the device was found and drivers were installed with success. It ran great for hours then, it started loading pages very slowly again? Then I plugged back into the onboard lan jack and it ran great, so I switched back to the pci card and got the same slow results again. I don't understand unless, my neighbor who also has wildblue can some how pull a drain off that card but I just have the dish which runs to my wildblue modem then to my pc nothing wireless? Maybe I just got a bad card any suggestions from anyone are sure welcomed. Thanks! Also, my neighbor is on s different sattellite.

If it runs good for awhile then slows down I doubt if it 's hardware related.

What else is going on with your computer when this happens?

Look at Task Manager, Processes tab. Click on the CPU column header to sort by CPU Utilization and see if anything shows there.

Perhaps something you are running is causing the problem? Download and install CCleaner from the following link: CCleaner - Standard

During installation, uncheck the option to install the Yahoo toolbar.

Start CCleaner. Click on Tools (ICON) and Select the following BUTTONS to create two (2) text files:

* Uninstall > Save to text file (install) – bottom right corner of app window

Locate and open each saved file in the ‘Documents’ FOLDER:
