Problems with advanced switches

Hello

This might not be the correct forum to post this into but Im gonna try
my luck anyway since this problem has bugged me for several days now.

I have two routers that I connect into a single advanced switch (tried
both a cisco 3500 and a dell powerconnect 5324). When I connect these
two networks at the same time they work, but only one at the time. For
example take two networks; 192.168.0.0/24 and 192.168.1.0/24. If I
connect these two and ping both simultaniously network 2 fails when I
get reply from network 1 and vice versa. Never does both networks work
at the same time. Also I cant control wether network 1 works or network
2 works, its just random. For example, network 1 works for aprox 2mins,
then network 2 works for aprox 30sec and so it goes.

Anyone experianced this problem before and knows what causes it?

I also want to add that if I take a non configurable switch, the setup
works without any problems and I have tried to setup VLAN's but the same
problem appears.

Thanks in advance.
