Knoppix Problems or Hardware Problems

Hi.
I got some serious problems with my system.
They may not be Knoppix. If their not I am having trouble figuring out if its the HD or the MB.

See...
when I a OS.

Windows XP, Mandrake, Gentoo, Redhat, Slackware, Suse, CollegeLinux.
Everything LINUX installs ok. Except Slackware which gave me a L 99 99 99 boot error, that i fixed. (old version of LILO)

When starting up the screen will Flash for a second or two. Then Will display the Linux Shell. Seems Xfree has a error starting up...

This is odd cause my graphics card isnt broken... Knoppix displays fine. Even reconizes whats card I have.

When I format either HD, and try to use them to store stuff for Knoppix. It gives me errors. Yet a Knoppix can save a config file to partion /dev/hdb1.

BTW i have
/dev/hda linux ext2
/dev/hdb1 linux swap
/dev/hdb2 linux ext2

So why can I save the config file on the swap. Not anything else though. Why cant I save anything on the other drives.

Also windows Xp when installed now, does not show themes. Only the basic windows theme. It also crashes Internet Explorer when u open it.
Which sucks since they use IE to browse everything.

Also You can't install hardware (meaning my NIC mainly) because it says windows is already to busy.

I have not stuck around long enough to find other errors. But the whole windows is messed up. (good)

But linux shouln't be...

I have tried formating both drives countless time, and reset the bios countless others...

I am very confused.

Only thing I can think of is its either my Bios (need a new MB) or my HDs.
Which is odd since same things happens on both.

I got to give major kudos to knoppix though. I can atleast get on the internet with it, and it gives me something to use while I try to get my problems fixed.
