Hi. First time here. Read the many posts of others who are having probs with Vista. I have an HP Pavilion with windows Vista home premium. Screen is saying: windows failed to start. A recent harware or software change....etc. From what I've read here, I need to burn a cd to restore my windows back to the time previous to the error. Only have one computer in the house, so will have to ask the neighbors for help on this. How do I know if I should burn the 32 or 64b? If I do go ahead and do this, do you think I will really be able to do it? I am very computer illiterate. I don't want to messthings up more than they already are!! I'm nervous.
