You said it forces you into bios, but you can't access bios. Which is it? Even if you can't boot into windows you should be able to just reinstall windows.
When i wack the Clear-CMOS switch, on my next boot it puts me into the BIOS. (This is the only time i can get into the BIOS)
Every boot after that Shows the military class II logo for less than a second, and then just sits on a black screen with a flashing underline.
The computer will not go into the BIOS by pushing/spamming the DEL key.
I have inserted the windows 7 disk to see if it would boot from that so i could try a fresh install. Even with the boot priority changed to read the DVD drive, it still just hangs and wont read the disk.
