Every time I try to start my computer, it loads Windows, gets to the starting screen, and then right when the desktop would normally show up, it then restarts. It's a never ending cycle... Is it driver issues, a virus? My specs are as listed below, plus Windows XP home, SP2, and I have NOD32 for antivirus. The chronology of events goes: some things started acting a little wierd. Computer is a little more slow than usual, my network adapter is listed as "disabled" even though I'm connected to the internet perfectly fine. Then suddenly my mouse stops working. Keyboard still works, but the mouse won't move. I swapped to a different mouse, and no luck, so I restarted, and that's when the whole boot/restart cycle began. I went into safe mode and did system restore, but no luck. The last thing I did was tweak my network settings a couple days ago, to open some ports for faster downloading. Anyone have any suggestions as to what I should do?
