ok so when i turn on my computer it goes through the normal things, the boot picture, then the system info POST screen, then it goes to a black screen that says "verifing DMI pool data" then it says "success" and that is immeadiatly followed by "Disc Read error occured Press ctrl+alt+del to restart" i restart and the same thing happens. then i popped a ubuntu disc in to live boot and the same error came up (i only enabled the DVD-RW boot and not HDD or floppy). so i unplugged the HDD and when it got to the "verifing DMI pool data" part it booted into ubuntu. i tried to access the HDD from ubuntu but it said that it was not accessable. so is the HDD dead? i just got the mobo back from RMA today and it was the same one i sent in.
i am not computer illeterate but i just cant figure out what is going on.
