I own a HDX18 and it all of a sudden started bugging out. First i would connect head phones and the sound from the speakers wouldnt stop, so i would hear music from both speaker and earphone. Sometimes earphones wont even work until i push down the right side of my laptop(where the earphone input is). So im thinking its a physical connection problem.

Another thing my 2nd HDD sometimes just disappears, then returns whenever it pleases

Lastly my TV card isn't detected anymore.
Can someone please help me and give me advice on how i can fix this.

Thanks in advance.
