Not really sure where to put this post. Here is what happened: I was playing some music in windows xp. Went to load up my favorite FPS game and the computer restarted, was able to load back into windows. It told me It had a 'serious system problem' in the windows kernal. So I tried it agian, the same game*. It restarted agian. This time It would load into windows, It got to the GRUB boat loader (I dual boot linux and WinXP) started loading XP to the point where I saw the XP logo and then the little progress bar underneath. This didnt last long, It restarted agian... So, I tried to load up Fedora Core 3. It would go either, It wanted to do an 'integrity check' and it scanned the root files, and it just left me there hanging. I was able to sucsesfully install ubuntu on some free space (writing this messege on it.) So, I was wondering whats going on? Is the first 2 partitions messed up? partition 1 is WinXP NTFS aka hda1, partition 2 is Fedora Core 3 ext3 aka hda2, a swap partition hda3, and now a ubuntu partition which is currently working. I have no Idea on this one, I figure they must not be completly lost. Any help apreciated, sorry on the thread placement, I have no real clue as to where to place it but since it happened in windows.... Thanks, Dan *Note: The computer restarted in the same place of that the game was loading both times.
