I recently wasn't able to connect to the internet, so i went to microsoft's website and followed the steps for fixing the problem (which was supposedly winsock2 related) and now my start button and taskbar freezes every time i start my computer. It also displays the Active Desktop Recovery Screen. If i terminate explorer.exe with the task manager the desktop comes back but running explorer.exe again i can open the start menu and then it freezes again and causes the same problem. Everything else seems to be fine (i can run programs from the task manager) but the start menu problem is the same.
I have tried an upgrade install from the xp cd but with no luck.
Also all of the problems started when i replaced the power supply and added a usb2.0/firewire/ethernet card and DVD+-RW drive (all of which were working fine except for the fact that i could not see pictures in IE6.
