In this paper, we consider the existence and nonexistence of nontrivial solutions for the following biharmonic problem with critical exponent {Δ 2 u= μ Δ u+ λ u+| u| 2⁎⁎− 2 u, x∈ Ω, u|∂ Ω=∂ u∂ n|∂ Ω= 0, where Ω⊂ R N is a bounded domain with smooth boundary∂ Ω, Δ 2= Δ Δ denotes the iterated N-dimensional Laplacian, 2⁎⁎= 2 N N− 4 (N> 4) is the critical Sobolev exponent for the embedding H 0 2 (Ω)↪ L 2⁎⁎(Ω) and H 0 2 (Ω) is the closure of C 0∞(Ω) under the norm|| Δ u|| L 2 (Ω). Under some assumptions on μ and λ, we prove the existence and nonexistence of nontrivial solutions to the above problem. Different from the case μ= 0, N= 6, 7 are not the critical dimensions of nontrivial solutions when μ∈(− β (Ω), 0), where β (Ω):= inf u∈ H 0 2 (Ω)∖{0}∫ Ω| Δ u| 2 d x∫ Ω|∇ u| 2 d x.
