attempt the restore point. Go back to before you renamed ASACPI.SYS to ASACPI.BAK.
After you restore, we should get your ASACPI.SYS issue fixed using the method in post #4
before doing any further steps.
Go to the link in post #4
. You will find the software update for ASACPI.SYS in utilities (not BIOS utilities, just utilities) and it is the first link under Utilities to download that software.
