My Specs: Dell Dimension 8100, P4, 1,5GHz, 32MB Nvidia MX, 384MB RDRAM and WINDOWS XP PRO. - I just bought Microsoft Intellimouse Explorer 3.0 and i was installing the drivers. After i rebooted the machine the keyboard locks up after it loads/starts windows, the keybaord won't work at all. I have tryed: *Another keyboard. *Removing all unnecicery hardware. *Updating BIOS to the newest version (A08 if i remember correctly) *Another graphic card (because when i start XP in save mode, it hangs on agp440.sys, when it's loaded or being loded.) ** To that i have tryed to rename agp440.sys to agp4440.old so it won't be loaded. ** Tryed PCI graphic card and removed the AGP one. I have't tryed USB keyboard, coz i don't want to buy one just for testing. ... ... I would be very pleased if someone could help me, this is very bad when i can't use my computer for work and i can't spend money sending it to technicals (because as far i have resolved all problems, both in my comp and many others)... Well, thank you.

Have you checked it out in device manager? I'd check there and see if there's any kind of conflicts. Sorry I can't be of any more help. I hope someone else can provide you with something a little more substantial then this.

Well, i can't log into the XP without keyboard. I have to type my password to get into the computer. The keyboard locks up just when the XP loadup/startup screen comes up after DOS. ....soooooo.... bad trouble!
