John; I think you may have answered your own question. If the problems started "after the network card and net were installed", I would pull the Nic card and see if the problems go away. If not perhaps some "net" related software installed after the Nic may be the problem. I have experienced some strange and hard to diagnose problems with various network cards, I usually try to stay with a name brand Nic (3com,intel,linksys,etc) they still can cause problems, but not quite as often. I'm not familiar with Compex Nics, but try another Nic card if that is possible. | --|--------------------------- | ><> Larry Fisk <>< | Fisk Computers | Fruitvale, Idaho ----- Original Message ----- From: "johnslaughter" <[log in to unmask]> Subject: [PCBUILD] > a compex ethernet card,and a cable net connection. the pc ws fast enough, but after the network card >and net was installed, it's slowed down to a crawl. the mouse gets stuck every few seconds, and the keyboard has a typing lag. the problem gets worse as time goes on.
