Hi i dont know an awful lot about computers but anyway here goes: i have a fairly new pc dell dimension 3000 with windows xp and while left on for a few hours i looked at it and it had crashed and there was a blue screen with unmountable_boot_volume on it. i tried restarting but nothing other than the BSOD. A friend who knows a bit about computers reinstalled windows xp but when it loads up theres no icons on the desktop. i can still open up mozilla and some other stuff and when i went into add/remove programs all my programs where there so it hasnt deleted my hard drive but it keeps crashing and goes really slow. can anyone help me fix this problem without losing any of my files on the hard drive. i worked so hard building up a huge music collection and fear for the worst. to make matters more annoying, i planned to buy an external hard drive the other day to backup everything but never got round to it. any help would be really appreciated!! thanks.
