General :: Cannot Boot, Black Screen After Bios Post?

I installed a Raid 2+0 a couple of days ago with windows 7, and everything was working fine until today. I left my computer for a couple of hours and when i came back all i see is this black screen with a blinking cursor, then i tried everything on the bios but every time i tried to boot it kept stuck there, right after the bios POST.Then i tried changing the SATA ports, that was something that fixed similar problems on my old Mobo, but this is strange because this mobo has 1 week, and the HD's (2x seagate 500gb) have 2 days, so they should be fine.

Then i tried with my ubuntu lucid lynx live cd, it has saved my life many times, it always works flawlessly and i thought i could use it to restore the boot files, but i was very surprised when it failed as well, it pops a message saying something like "invalid user pwsuid "user: unknown"{0}". Tried it many times with no luck, only that same message...Now i managed to boot from a "slitaz" linux dist. thats about 30mb, it has many useful tools.I can see the partitions/HD's on the Gparted and mount applications, but i still i havent managed to mount the raid i had on my Windows 7 install, im a bit scared of losing data, and i dont even know how to do it.Is there any way to fix thisrom the slitaz live cd?Maybe i could mount the Raid and then restore the Boot files from the slitaz live cd? I have a windows image i could use on the Raid, and i could copy the image files to a partition, make it primary, active and bootable...I really dont know, maybe that wont help either because the ubuntu live cd couldnt boot, i really dont know what whats going on and what could be the cause of this... maybe a worm/virus
