Hi, I'm not really much of an expert on computers but I've been having a little trouble. It started off when my brothers installed Windows 7 onto my netbook, which was installed with XP so I could run whichever I chose. After using 7 for a while it would go into the blue screen of death and then crash shortly after, I ignored this for a few months until this week when it crashed and when I restarted it it wouldn't log on. Whenever I tried to select Windows 7 it would either just loop itself back to the start or turn off all together. So I used XP for a day or so and now that's doing the same. Does anyone know what's happening to my netbook?
