Windows worked smoothly for 3-4 days only

Now it’s hanging up in Windows 7 Bootup Screen in normal mode.

While booting in safe mode after loading some FILES it shows a Blue Screen for a second and restarts.

gOS Live CD showing Hard Disk but not able to mount it,
Partition Editor of gOS is not able to format/delete/modify Hard Disk.

Ubuntu Live CD & Gparted Live CD are not showing Hard Disk

While installing XP it’s not showing Hard Disk

While Installing Vista/Windows7 it hangs at Windows Logo bootup screen
