I just tried to reinstall Win XP and I get these messages: 1. When I try the original cd with Win XP Pro SP1(which it did worked last year when I did the last reinstall) I get this : File\i386\ha laacpi.dll could not be loaded.The error code is 7.Set up cannot continue.Press any key to exit. 2. When I tried with a copy of Win XP Pro Corp SP2(which I never used before) I get this: File acpi.sys caused an unexpected error(8192) at the line 5964 in d:\nt\base\boot\setup\setup.c. Now please if somebody knows what the heck is going on?Basically I can't reinstall my OS! Thanks!
