after choosing a wallet Bitcoin core, they have a 7 years system sync which i am a first time user. I didn't know that and money was sent to the account. I can't access the money. It is not showing up. Back to the issue besides where is my money. My computer can't upload all the syncing because it is running out of memory. I backed up my computer erased most of the backup and still don't have enough memory. so someone please tell my way your app takes up and over my whole computer. Please get this to work as i am not a tech person or anything but i am extremely disappointed with the tech side trying to help.
You can configure Bitcoin Core to run with
--dbcache=50 which will limit the database cache size to 50MB (default is 100MB). You can read more about it here.
Alternatively, you probably don't need to be running a full node, and should instead consider using an SPV wallet, which will consume a lot less of your system resources.
It sounds like you've got money in a wallet already?
Perhaps a better option is to get a lightweight wallet client and then get the wallets managed in that.
That way you can avoid having to sync the entire blockchain on your machine.
