Big white space between header and menu

Hi guys,

I am hoping you can help me as I have been trying solving this for the pas few days. 🙁

I got a big white space in my wordpress theme after I have added header slideshow. But it only appears in IE browser. No problem in Chrom or Firefox.

I have tried messing around with style.css as someone mention on the previous post but had no luck 🙁

Can someone take me step by step how to do this? Will really appreciate this 🙂

Thanks in advance for your help.
