Here's a good one. I had a virus on my computer that messed up everything. So I decided the best course of action would be to reinstall windows. Good idea right! I backed up all my important files onto a cd. I know the virus could be on the cd's so I'm taking extra precautions. I have one hard drive (40Gb) split into two partitions. A primary partition for a windows OS, and an extended for all the crap that piles up. I did that so if windows stopped working I could delete windows and reinstall it. I reformated C: and reinstalled windows for that time. I did that once when windows had a lot of fatal messages when turning on my computer. When doing that C: stayed C: and D: changed to F:. I tried formating C: a second time. That didnt work out so good with the virus problem. I tried to repartition my drives and I delete the extended but it said i didnt have one. Then I tried to make an extended partition and it said i had one already. The only thing that I can come up with is that I reinstalled windows once before and it changed my one partition from D: to F:. I didnt think anything about why it changed the letter. Can anyone help me
