ive had an ibanezrgt220 for about a year now and its just now starting to give me some trouble. i love floyd rose and the tremelo and all that jazz but its been giving me some problems lately. the guitar will not hold strings for longer than 4 to 5 days. the strings will just snap right at the bridge. in the back of my guitar there's a little area that holds 5 springs and ive noticed there are only three in there. in this order:

I I . . I

the I's are springs and the dots represent no springs

anyway i was just wondering if possibly this has anything to do with my strings snapping continuously? maybe i should try some heavier gauge strings? i use slinky hybrids and tune to DGCFAD. thanks.
