USB Get Halted

Hi Guyz..
I Bought Envy-dv6 i7.
I've Been Using My Laptop Since 8 month and It Works Flawlessly..
But every Now and then I Face this Issue. Suddenly All My USB Gets Halted After Plugging In Any USB Drive Or Mobile Storage.
And after that All Of the Ports Doesn't Work What Ever I do..
The Only solution Is, Restarting My Laptop.. But I Cannot shutdown Or Restart It Normally .. It Keeps on waiting on restarting Screen.. And After Waiting for 5-10mins it shows a blue screen error And I Have To Directly Shut Down My Laptop By Pressing Power Button..
Any Help Would Be Appreciated.
