A few days ago, my dad's computer wouldn't boot up saying a file in the system32 folder or something is corrupted or missing. So we switched it with a new hard drive to reinstall the OS(Windows XP), but it won't even start booting up, it just stays a blank screen after the system information shows up. What could this be?
BIO is still the same, I'm not sure, but when I connected the old hard drive it worked, I'm not sure what the heck's going on... But I was wondering what happened for the file to go missing or corrupted.
I know that ACPI has to do with controlling the power, but what exactly does it do? For the missing file, I believe it had something to do with registry, some like the ROC file or something, I forgot to write it down.
