IE 6 sp3 system crashing End Task

[Lindaleee]

oh help me please....
I have a new Dell 530 installed ie6 sp3 and the system selectively crashes when it wants to.
I get an end task error that ie must close
Event ID Application error faulting application iexplore.exe version 6.0.2900.5512 faulting module ws2_32.dll 5.1.2600.5512 faulting address 0x00004cb7
or faulting module wsock32.dll faulting address0x00002e73

is this a winsock issue. I use winxp pro cable modem which has been checked and works fine. I have checked for malware and viruses.
Anyone have an idea what it is?

Thanks,
Linda
