Motherboard Intel DQ35MP. HDD Caviar Green 1TB.

I'm having problems with my BIOS and/or hard drive/disc drive.

Came back from a trip, booted my computer, and realized that the BIOS wasn't booting anymore, just a black screen with no beep sounds. Only fans and lights on. Then I thought it might be caused by the video card, I removed it, and still no BIOS screen. Then I removed the hard drive and voila BIOS screen is back again. If the hard drive is defective then I can check that with a Rescue Disk. I inserted the CD on the Disc Tray but the computer did not respond to it, the screen freezes in black with an "E7" string at the bottom right corner just after the BIOS screen, this happens with or without discs.

BIOS settings are set to default, and CD reading is on top of the boot device list.

EDIT

I removed the BIOS battery, rebooted the CPU, the BIOS screen showed up, and then it freezed in E7. Placed the BIOS batttery, rebooted and same thing, we are stuck with the E7 string.

I uploaded a video to illustrate the problem http://www.youtube.com/watch?v=13jPdBcIrBU

12.04 upgrade broke grub? (not wubi related)

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
