532022 Websit Debug (Site crashes internetexplorer)

Hello, I have a website and it crashes internet explorer but not all the time. It is perfectly fine however it keeps crashing internet explorer. I tested it ie6-ie7 and ie8 all of them crashes. I guess it is a javascript problem or due to pngfix we applied. Im looking for a programmer to debug site, fix js errors, and find the couse of internet explorer crashes to fix them too.
