I was setting up my computer as i have moved house and the mouse decided not to work, so i shut down the computer and tried plugging it in again. After thousands of tries it finally worked but after a short while the mouse froze. I then restarted the computer a few more times, then it froze and i had to turn it off by the wall. Now an error message is coming up and i can't do anything, i can get into set up, tried rebooting it in safe mode and last known configuration but after the windows logo comes up it then goes back to the error message.

The message says that there is an INACCESIBLE BOOT device.

Any ideas?Anytime a computer has been moved theres a chance of things getting jostled around so here's what i'd suggest...
Power down and remove all cables from the back of the machine.
Open/remove a side panel and remove and re-seat all RAM chips, add-on cards including video sound etc.
Remove all drive cables and re-plug them firmly.
Then hook up all cables at the REAR of the machine.

Leave the side panel off for now...re-connect power and boot up and see what happens.
Best of Luck and let us know...Thanks for the advice. I took the computer apart and put everything back together but nothing SEEMED amiss. Once i turned it back on it still kept showing up with the same blue screen but this time it's saying on another screen that the hard disk isn't working. Ive tried everything i can think of, EVEN trying to re-install windows dosen't work because theres something wrong with the hard disk.

If you have any ideas that'll be great thanks.Moving can, indeed, damage a hard drive.
