When you attempt to install Windows XP, the installation process may not complete successfully. Setup may stop at the beginning of the process or immediately after the first required restart, and then you receive an error message similar to the following:
An unexpected error has occurred. (536821760) occurred at line 1768 in D:\xpclient\base\boot\setup\arcdisp.c
This behavior can occur because of damaged random access memory (RAM) modules or a damaged RAM slot.
To resolve this issue, use one or more of the following methods, as necessary:
Remove one or more of the RAM modules in your computer, leaving at least the minimum amount of RAM required for Windows XP installation. If this resolves the issue, either replace these modules with new RAM modules or reinsert them after Setup is completed.
NOTE: Verify that your computer's performance is not affected when you reinsert the old RAM modules.
Install the RAM modules into different (unused) RAM slots in your computer.
If you still experience problems before or after Setup, replace all of your computer's RAM modules with new RAM modules.
