All the ones labeled crap disable them. Also with config will automatically
pick what it needs to have on to run so hit Disable all and go from thier. XP is pretty stable so you should be able to figure out which porgram of these runs the internet.
I think it is
gcasServs.
Do this as a Last Resort
Format your drive. How long has it been since the last one you have done. Very Important Make sure you have the Disk or follow your PC directions on Formatting expecailly if your PC has XP in the Hard Drive as a Partition. Good rule for Formatting is about every 6 months or so.
I have gone over a year since I last Formatted my PC. I am so Lazy but my PC is working just the way I want it too so I dont want too formatt since it takes a few days to get it back to the way you like it not to mention that Ill have to download FF11 updates again >.<.

Again Format should be your
last Resort and is always a good idea to find out what is causing the problem so you dont do it again.
