Thank you!

So first, im a big noob when it comes to Bitcoin so please keep that in mind.
Last week i created a normal electrum wallet with a seed and a password. Then my computer crashed and all data was gone. I still have the seed but how can i get into my old account with the +0.5 B ? I dont have tried many ways because im not sure and i want to do nothing wrong. You would make my day way better when helping me with this problem.
