```Dear Expert,
I have some problem running Mathematica  and it is taking too much time. Can you help me?

Regards
Swarup

eqns = {AA'[x] + I*b*EE[x] + c*CC[x] + d*AA[x] == 0,
BB'[x] - a*CC[x] + I*b*FF[x] - c*DD[x] + d*BB[x] == 0,
CC'[x] + a*BB[x] + I*b*GG[x] + c*AA[x] + d*CC[x] == 0,
DD'[x] + I*b*HH[x] - c*BB[x] + d*DD[x] == 0,
