"Load needed DLLs for kernel" WITHOUT CD?

I have an Acer Aspire one a150. It came with absolutely NO CD's because it has no CD Drive. I got a problem in which Windows XP won't start "because of an error in the software. load needed DLLs for kernel." I tried calling Microsoft Tech Support, but they no longer help XP and even if I did pay them $60, they told me they could only help with the CD. Either that support guy was stupid, or I'm truly screwed. Is there any way of resolving the issue without a recovery CD at all? Considering that I never got one in the first place?
