While processing graphics I got the -kernel data inpage error- message, I followed the steps, but nothing happened, I tried safe mode, but the computer did not start.

The computer goes from the -dell, screen- to the -windws xp screen- and back to the -dell screen- several times. I called a friend who told me to remove the memory for some minutes and reinstall the later, I did this process and windows worked, but after moveing the mouse, the same message appeared -kernel data inpage error-, auto restart happened again.

I tried repairing windows by booting from CD, and I could not delete or add a new partition, I tried repair (R) but it did not work, and suddenly the next message appeared -unmountable boot volume-. Now I have formatted the drive, but still can not add partitions or delete or continue with the process.

Any help?
