advice on replacing a sub woofer

I have the Athena Technology Micra M225 Surround Sound system. The subwoofer on it has broken. Can anyone recommend a substitute so that I do not have to replace the entire system. Here are the specs:

Looking to spend no more than $300

1) do the speakers have to be pluged into the back of the Sub. Some HTIB add custom plugs and the speakers only can be pluged into the sub, but that sometimes can be 'fixed' with some cutters. It sounds like there plug into your reciever, just want to make sure.

2) What type of flooring do you have? Downfiring subs are really only good on hard floors.

Can the sub be any size or does it need to have a small profile?

the current sub is 16.7" x 14.2" x 9.4"; could go a little bigger if necessary, but not much.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
