Logitech G510 Gaming Keyboard Broke

Today I was playing my usual minecraft, all of a sudden, keyboard breaks, when I say breaks, none of the keys actually work, after about 5mins of trying to get it to work, unplugging it and repluggin it, I noticed that I have to hold down a key for atleast 2seconds before the key actually registers, I didn't know why this happened but it did, so now I have to hold down the key for atleast 2 seconds before it works, is there any way I can fix this? If there's any extra info needed, tell me and I will put it in, thanks!

Depending on the time you had with the board depends on the life of the keys. If you need to press hard then your board is prob done for.
update the software on it. Unistall and reinstall.
if its old get a new one.
