|When you say "clean install", do you mean that you removed all partitions, then created a new one on which to install Windows?|
If not, that could be a part of your problem. XP seems to have a problem as far as picking up garbage from previous installs, unless the partition is removed and re-created.
I see no mention of anti-virus software in your post. After installing Windows, then the motherboard drivers, you should install your AV software (all before connecting to the internet). Update your virus definitions immediately. If you don't use anti-virus software, then you deserve all the grief you get.
I think your best option is to start anew.
