All righty, I switched motherboards out the other day. Booted up Slackware and the only thing it asked for was a change on my display settings. Everything else went fine...booted up normally, etc. Last night, I was listening to some mp3's on Samba without any problems. Then today, Samba is down, I can't ping linux, nor can linux ping anyone else on the network. I have not touched any files since the motherboard was reinstalled....well except I noticed my hosts file was changed and had to add the hosts back. But I have checked everything I can think of...samba start/stop, eth0 settings, rc.inet1, hostname, resolv, etc....what do I do?

If you can't ping, it isn't Samba.

First, check the hardware. Are you wireless or wired? If you're wired, check both ends of the wire to make sure they're plugged in and show a Link light. If you're wireless, do you have other computers on the network where you can check your AP to see if the computer is seen?

Have you tried starting/stopping your ethernet?
If all else fails, have you tried a cold reboot?

Got it up now. Needless to say I dunno what happened. I rebooted and after the system information screen, the screen went black....still received a signal but just black. No LILO or anything. I checked all connections, everything was fine and was starting to fear my 80GB hard drive bit the dust. Then I just made a few mods to BIOS (nothing extreme....think I disabled Quickboot for one) and after that it booted up just fine. Weird.
