problem with lan card :(

[TechGod]

hi guys , i have problem with my lan card , its breaking connection continuously like when i run any app which put some load on pc ( like jetaudio , any browser , or any other normal app )or even sometimes when i refresh my pc ,

network connected n disconnected bubble in tray is just pissing me off (well i closed it with registry edit )

i already checked some common procedures like

>uninstall and reinstall lan card drivers

>re installation of winxp

>changed wire which connects my external router to lan card

>checked with another new router

>> i replaced my old lan card with new unpacked lan card ( yes i did unpacked it with my own hands )
but its still giving same problem :(

How do you connect?(dsl, cable, wireless) If DSL or Cable what is the brand name on your modem and both of your routers that you have used. You just aren't giving enough info.

[johnwill]

Have you tested the cables with other computers?
Have you tested the router ports used with other computer?

Probably time to replace the NIC.

Hard to suggest much when you don't want to provide the requested information.
