Computer Speakers 5.1

What is the best way to set up a 5.1 speaker if i cant place the rear speakers at the back?

i bought a 5.1 surround computer speaker, but after i bought it, it doesn’t work as planned. I cannot place the 2 rear speakers at the back for some reasons. Please advice me how to place the speakers.
Thanks a lot,
Kenny

Rear speakers should actually be positioned at head level directly to the right and left of where you sit to view the TV/computer. They are not actually suppose to go behind you.
