It looks like your tension isn't equal, the strings are pulling more than the springs. It's easy to have this happen if you're not familiar with the basics of tuning a guitar with a floating bridge. You'll have to increase your spring tension and retune. And keep doing this until the bridge is a almost level with the body and is still floating. It's an irritating thing to learn but once you are familiar it's easy.

If you're using 2 springs you may have to add one because you might run out of adjustment in the rear cavity where the screws are to increase the tension. And keep in mind while tuning in the future, Every time you tune a string, the others are changing because you're changing the tension balance across all strings.

If the bridge is supposed to dive only, not float at all, and rest on the body... All you need to do is increase your spring tension enough to keep the bridge against the body. Then tune, if it starts to float again increase the tension until it takes only a little pressure on the trem bar to dive once the guitar is in tune.

But if your bridge is rising without you doing anything at all... That sounds pretty weird... And my best guess would be, it's time for new trem springs.

Hi thanks for your help!

The bridge is not floating it's supposed to rest flat against the surface of the body... any tips? Thanks again

Yeah man, I know my response was long winded, but in the third paragraph I explained what you should do. Glad to help!

Thanks! Just to clarify when you say I need to increase the spring tension does that mean tightening the two screws that hold the springs in? Because they are as tight as they can go...

Yes, that was what he meant. You adjust the springs to keep the bridge level when the guitar is in tune. If yours isn't full floating, then adjust them tight enough to have the tremolo bottom out on the guitar body. That will also make it super easy to tune! Sounds like you may be missing a spring? Most guitars use 3, but I have one that needs 4 for some reason.

Hi thanks for your help!

I've looked and it has two springs but they are both tightened up as far it can go? I'm not sure what to do? Thanks again...

Looks like it's time to buy a new set of springs. They come typically in sets of 3 or 4. If you have a third one around put it in. Did you recently get the guitar? Or did you install heavier gauge strings on it then you used to use? Those could be reasons why the bridge lifted. Regardless... You need springs.
