unstalling windows xp sp3 upgrade

[paul62]

I am using windows xp on a hp d530, and I am having trouble installing sp3, how can I boot this system into safe mode? I may have better luck installing the upgrade this way. I am getting the error message "Thefile c:\windows\system32\drivers\atapi.sys is open. I would appreciate the help.

Have you scanned thoroughly for malware? atapi.sys is a known malware hide, and the malware can be protecting itself from being overwritten.

I have tried scanning fro malware and viruses, and have had no luck. I have tried downloading sp3 before installing iit and no luck I have tried using unlocker on this file and cannot move it unlock it or rename it.
