Windows 7: MSI: p55-cd53, onboard lan acting weird? Works in "msi winki" not in w

Hi
I just formated my comp, nothing new added except two older hdds from another comp, removed them so thats no worry atm, but the onboard lan just stopped getting detected for some reason?, i cant understand it, its been working perfectly, and it does work if i use the "MSI WINKY" browser and the onboard lan with cable connects to the internet without a problem, but as soon as i enter windows, its gone, nowhere to be found in device manager, when i flashed my bios to the latest version the onboard lan got detected for a few minutes but was gone after reboot, so.. im kinda good with computer and it feels like ive tried everything but now im lost.. any ideas?

Thanks

You should try powering down completely, unplug the machine and bleed off extra power by holding down the start button. If the onboard LAN doesn't show up try clearing the cmos, set bios to default, then go back through the bios and make sure everything is set correctly.
