internet Explorer got problem

Dear sir,

The problem is I can go msn online but sometimes encounter debug problem but I can’t browse internet webpages.I can enter my hotmail mail account through msn and can see how many mails i have got but just can’t open up my mails.The error is webpage cannnot be displayed.I have a explorer 6 pentium II. I have reinstall the explorer but still won’t work.I am sure there is not problem with my ISP. In option menu I have set everyting default, but still won’t work.

Any advice

Thanks!
