Ok MR FOXYLOXLEY...

The reason why i have this PC is because im a skint student who cant afford to buy a new one! Thus the reason why i am trying to sort this problem out and not buying a USB mouse.

Secondly, the reason why i am missing capitals is because the keyboard i am using is dodgey and some capitals dont work.

Thirdly, the reson why i didnt want to type the irq's is because THE kEYBOARD S DODGEY AND i DONT HAVE A MOUSE TO COPY AND PASTE!!!

Now, MEPSiS = LiNUX, i know irq shouldnt realy matter with xp but i think it is being configured before it reaches the OS as when i boot with LiNUX the mouse still doesnt work. The mouse is tempremental i.e it does work sometimes.

i cant work out what the prob is, maybe dodgey hardware... Another thing that i thought it could be, is that the processor is to fast for the motherboard?

s there anyway that i can assign the mouse to a different irq address e.g 3 or 4. One weird thing that i noticed, is that the graphics card is using irq 12, this irq address is normaly for the ps/2 mouse?

anyways, if you need all the irq addresses put up i will do so, and hopefully i have made things a little clearer.
