Hello Parker,
Thanks for your posting here.
The 0x0000007a error code indicates that the requested page of kernel data
from the paging file could not be read into memory. As atapi.sys is your
basic IDE hard disk driver, it''s mostly likely that your hard disk or hard
disk controller is bad.
Please first check the issue in Windows Safe Mode. To do so:
1. Restart your computer and start pressing the F8 key on your keyboard. On
a computer that is configured for booting to multiple operating systems,
you can press the F8 key when you see the Boot Menu.
2. When the Windows Advanced Options menu appears, select Safe Mode, and
then press ENTER.
3. When the Boot menu appears again, and the words "Safe Mode" appear in
blue at the bottom, select the installation that you want to start, and
then press ENTER.
Note: For more information about Safe Mode boot options, please refer to
the following article.

Does the issue occur only to the certain program or whenever performing any
operations in the system? Did it start to occur right after installing
Windows XP or after adding a new item (a device or an application)?
