The following shows on my screen when I start up… Resource conflict Serial bus controller on mother board Bus : 06, Device :00, Function: 02. Resource conflict PCI mass storage controller on mother board Bus:06, Device:00, Function:03. I was advised that I should reinstall windows should I ? If so as I don’t know the first thing about how to do this , I would probably go to a pro. I am using acronis 10 build 4942 My laptop is an LG 6o (with 30% free memory) O.S. Windows Xp Home Backup is to an external hard drive ( lacie) Security is Spy bot,Avg free, Windows defender. I have recently defraged 3 times From studying the various Wilders threads, I note also that it was said that if you did a complete/full backup (disc image) that any faults /corruption in your O.S. WOULD BE REPRODUCED in the acronis RESTORE? Is this true ? If so my computer is still running intermittently and I may. be able to do another backup…..Should I backup FOLDERS & FILES only or DATA only, so that I will have a useable (not corrupted) backup that can be restored. After reinstalling XP Home. Up till now I have only done full disc image backups and I have not tested the RESTORE operation. Many Thanks in advance , all input and advice will be much appreciated.
