    In the work we propose a new approach for studying the asymptotic behavior for large $x$ of the solutions to singular linear two-terms differential equations $$-\frac{d^n }{dx^n}y(x,\lambda)+\lambda q(x)y(x,\lambda)=0$$ with a potential $q(x)$ growing non-regularly as $x\rightarrow \infty$. The idea of constructing the asymptotics for the solutions of singular linear differential equations and its effectiveness is demonstrated for $4^{\mathrm{th}}$ order equations with an oscillating potential.
