Internet explorer is retarded

Ok, i have some stupid problem w/my computer. Im running Xp home BTW.

Ok - sometimes, when i load up IE, it starts working (i.e. loading the website hstuners.com) but then it just closes itself - no error messages of any kind - what could be causeing this? its almost as if somebody is hitting the X to cancle the program, but im not doing that.

I have scanned my CPU with Norton antivirus about 10 times and its found nothing

i dunno what to do.
