Strange plot in PSpice Student after reducing maximum step size

Question

I have run 10m simulation in PSpice Student 9.1 with Analysis Type: Time Domain (Transient) with max step size 100u and I get such plot:

max step size 100u

I wanted my plot to be more smooth so I have changed max step size to 100n and to my surprise plot looks like that:

max step size 100n

Can anyone explain me what has happened and how can I smooth my plot ?

EDIT: CIRCUIT enter image description here

Rc = 5k, Re = 2k, Ro = 10k, Rg = 40k, V1 = 20V, V2 = 6V, VOFF -1V, VAMPL = 1mV, FREQ = 1000

What would you like me to provide ? I can insert some file but I do not know with what .extension or I can insert printscreen of any Simulation Setting tab but I also do not which one would you like to see ? — Al Bundy, Mar 29 '15 at 22:48

Ok I have solved the issue. The problem was with Relative accuracy of V's and I's option. It is under Options tab in Simulation Settings.
