That's all you see?
Keyboard failure - nv4_disp on 8300 I have a blue screen with the nv4_disp failure message ie device driver got stuck in infinite loop. I have tried booting up in safe mode and part way through there is a 'keyboard failure' message. I belive nv4_disp are your nividia display drivers, you may want to see if going into safe mode, and DELETING your nvidia drivers (only your display drivers) fixes the problem.
Does it really look something like this:
***STOP: 0x000000EA (0x81997AD8, 0xFFB0E108, 0xF969BCBC, 0x00000001)
What does the rest of your message look like (those are clues).
That looks like an nvidia file, but is that all it says - nv4_disp with no extension? Does it really say nv4_disp.dll or something else?
Do you have nvidia video components and do you recall updating anything in that area lately? New drivers, new anything?
Fill in the blank: My system was working fine until ___________________.
Next time you boot, from the F8 boot options menu, choose:
Last known good configuration
That is the configuration XP saved the last time it booted successfully, so if you can boot there, you can undo/fix the other problem. If you installed a new video driver, you can roll it back and get the correct driver.
I have read that sometimes suspicious RAM comes into play with this error (maybe), so you can test your RAM like this:
Run a test of your RAM with memtest86+ (I know it is boring and will cost you a CD).
Memtest86+ is a more up to date version of the old memtest86 program and they are not the same.
The memtest86+ will not run under Windows, so you will need to download the ISO file and create a bootable CD, boot on that and then run the memtest86+ program.
If even a single error is reported that is a failure and should make you suspicious of your RAM.
If you have multiple sticks of RAM you may need to run the test on them one at a time and change them out to isolate the failure to a particular single stick.
Always keep at least the first bank of RAM occupied so the test will find something to do and there is enough to boot your system.
Sometimes, reseating the RAM in the slots will relieve the error but a failure is still cause for suspicion.

The file and instructions are here:
Here is a link that shows you have to create and use the memtest86+ CD:
If someone says to run memtest86, you can tell them to go pound sand and that you know memtest86+ supercedes memtest86 and here's why:
