so you are having multiple problems?
What is XP "HE"? Do you mean XP "Home"?
making several guesses I will attempt to clarify your problem (please take notes if you plan on asking questions in the future):
Title: Windows XP lockup problems
Body: Hey guys, I'm running Windows XP Home Service Pack "X" and it has the tendency of locking up after about 15 min. Generally about 2 min. before it locks up my internet speeds slow to a crawl (I'm using cable internet). I've run Windows updates and installed all the critical updates listed. I also run virus scanner "XXXX" and have ensured I am running the latest virus updates then scaned my HD, it came up clean. Do any of you have suggestions as to what is causing the problem? Thanks in advance for the help!

If I got all that information correct my guess would be NIC related, have you tried looking for updated drivers for your NIC? Are you using a PCI/PCMCIA NIC or a USB one? Have you tried swapping it out for a differant one (differant chipset so differant drivers) and/or running it in a differant PCI slot?
