problem with my notebook pls anybody help

Hello,
I am having trouble with my Internet explorer.It is doing some very odd things.Sometimes it will completely close the page i am visiting for no reason or it will be very slow loading pages and when i say slow i mean very very very slow for eg i tried to google something and after 10 minutes of the page trying to load i gave up.I thought that it was perhaps the topic i was searching so i tried putting in random things to see if that made any difference but it didn't.Another problem i had was when i was on a forum and clicked on a link and nothing happened i tried to open a new tab and that wouldn't work either and it would let me access any options that are in my tools menu.i had to restart my computer.Just to let you know i have high speed Internet connection.Thanks in advance to anyone that helps me with this problem.

Helen, dont know about your laptop, but on my desktop that has happened a few times to me. viruses or sometimes ie crashes or gets corrupt, or system out of memory. I ususally restart or repair ie and got a memory defrag usually helps mine, but dont know if running high speed would be any different than dial-up, sometimes my isp runs slow so that makes pages load slow too. if all else fails u can always reinstall your operating system lol. Done that lots of times too. just thought i would share what i knew with ya!
