I'm using a Dell Dimension E310. I recently upgraded to SP3 on my windows xp. Now It can't start up, and gives me this message: Windows could not start because of an error in the system. Please report this problem as: Load needed DLLs for kernel" I've looked up a few sites on how to fix this error. Everyone keeps suggessting reinstalling windows. I don't have a windows installation CD. I got this computer 7 years ago. Now the difference with my situation is that I have both vista and XP on my computer. So I'm still able to access the files of my XP through vista. Now I hate vista, and I would like to get my XP working again because Most of my work and programs I use are on that side. My question is this: Is it possible for me to fix this problem without reinstalling if I am still able to access the files ? If so, Please let me know. Hopefully I just need to download a certain file and insert it in the right folder Thanks.
