Overtraining?

Squat
280 lbs
5/5/5

Bench Press
215 lbs
0/0/0

Pendlay Row
135 lbs
5/5/5

I don't know exactly what's up, but something obviously is. Around a week ago, I Benched 3x5x210 lbs without too much trouble, yet I couldn't perform a single rep today. I'm beginning to believe my Overhead Press is interfering with my Bench Press.
