Windows 8 Shutdown issues

Hey guys,

So I recently got a Dell Inspiron 14R 5420. It's come loaded with Windows 8. I've found that it has shut down issues. Every time I try to shut down, it just doesn't go off and remains on the shut down screen forever. I've literally left it like 4 hours on that.
I read somewhere and tried disabling hybrid shutdown. That didn't fix it, and I've been force shutting down whenever I have to. I just read something else about flashing the BIOS.

In case this matters, its got an Nvidia GT 630M graphics card, 4gb RAM and 500 gb hdd.

Anyone experiencing this problem with Windows 8 and is there any solution?? Thanks in advance.
