CPU/Mobo LAN Card does not get detected sometimes?

[sam9953]

Hi guys, I have recently started to face another problem with my PC, my PC is nearly 8 years old and the LAN card is also nearly the same age and recently what is happening is that my device does not recognize the LAN card and does not read it, because of this the internet does not get connected as there is no LAN connection, the thing is that this just happens sometimes, not always. Any idea what the problem might be?

Pull out the lan card and use an eraser to clean the contacts. Then, use some pressurized air to clean the PCI slot.
