Problem of insert instead of dump

Hey all,
I was wondering maybe someone can help me solving this little(or maybe not) problem, I just recently bought a new comp and I had a large MySQL DB stored on the old one, now when I moved all I had little time so I did copy create like insert to all the table(instead of exporting the tables) now the table are not small, and I get memory exceptions when I try to run the queries, I tried to cut the queries but its a lot of tables.... also not so wisely I format the old computer before I checked it was alright.
thank you all, in advance
