Trap 00000006 Exception in Conjunction with USB Device

I have an older model eMachine (T2865) that originally came with a Western Digital (WB1600AB) hard drive. The computer was new when given to me in 2005 (e.g., never taken out of the box), but I have repeatedly had issues with the hard drive and so opted to replace it with a Western Digital SATA Drive running on a Promise Technology FastTrak TX4310 controller card.

I have successfully installed Windows XP (including all SPs) and the hardware drivers and the system boots beautifully, UNTIL I attempt to plug in a Microsoft Natural Ergonomic 4000 Keyboard. Then the system will not boot and generates a Trap 00000006 Exception Error. My assumption is that there is still something not set right for USB devices.

The trap exception error is as follows (NOTE: This is typed manually as I have no way at the moment to cut and paste the original code):

TRAP 00000006 exception tr=0028 cr0=80000011 cr2=00000000 cr3=00039000 gdt limit=off base=0003F000 idt limit=07FF base=0003F400 cs:eip=0008:003ED233 ss:esp=0010:0005F958 errcode=0000 flags=00010016 NoCy NoZr IntDis Down TrapDis eax=00008000 ebx=00008000 ecx=00488000 edx=004800E4 ds=0010 es=0010 edi=7E002581 esi=00488000 ebp=0005F978 cr0=80000011 fs=0030 gs=0000

Although the mouse is also a USB device, it is not currently operating as USB and has a USB-to-serial adaptor connected to it. Initially, I thought the error was an NTLDR issue and went through the process of replacing the NTLDR file; however, this did not resolve the Trap 00000006 error.

Any adivce you can offer would be greatly apppreciated. I have searched and searched the Internet for something related to this error in conjunction with USB devices and have been unable to locate anything.

Thanks!
