Wireless Keyboard Crashes Computer

[The_Llama]

I'm putting together a computer out of spare parts, and I bought the LiteOn sk-7260 wireless keyboard and mouse bundle. The Mouse works fine, but every time you hit one single key on the keyboard, it freezes the computer. It's a ps/2 connection for both the mouse and keyboard. (One wire splits into 2 ps/2 connectors.) I had this problem once with my computer. It was a cordless set by logitech. I found that when I put the keyboard into the USB port instead of using the adapter to the ps/2 port, it solved my problems. However, That's not an option here. Here are the specs

AMD Athelon xp 2600+ ~2.0 ghz 266 MHz FSB
Asus A7V600-x (my guess is this board is part of the problem)
1 ghz DDR400 Ram
Windows XP Pro. SP2 (it crashed on the original install and on sp2)
ATI Radeon 9600 128mb agp
Maxtor 120 gig hd in 3 partitions NTFS

As far as I can tell, there are no drivers and no manuals on the web for this set up. The disc it came with won't even let you autoplay it. It tells you win xp has what you need. Exploring the cd turns up nothing as well, except a lame Readme file.

There are no conflicts in device manager, and the keyboard is shown as installed and working properly.

The BIOS has plug and play enabled, and has ps/2 support enabled. I also left Legacy USB enabled.

If anyone has any ideas, I'm open to them. Right about now "throw it in the lake" is looking like the best idea.

Toss it. USB wireless KB are much more reliable and not that expensive. I didn't even realize they still made PS2 only based wireless units. That's 1990's technology. Get a MS or Logitech wireless combo. I use Logitech and they work great.

Yeah, I have the MX Duo for my main computer, but I grabbed this set up 'cause it was cheap. Once again, I get what I pay for. I was just really hoping for a simple solution that I was missing.

It kind of a kludge but if the MB BIOS allows it you can try dedicating/locking out the IRQs for the PS2 keyboard and PS2 mouse so no other drive shares them

IIRC

PS2 keyboard uses IRQ 1
PS2 mouse uses IRQ 12

Interference with the mouse IRQ is by far the most likely problem. See if anything is sharing IRQ 12 (video or sound card mostly likely) and see if disabling or moving the IRQ assignment (if possible) it solves the problem
