|That blinking white line means that your computer is having difficulties "Booting" (Loading some sort of operating system either off the Hard Drive or off CD DVD etc). Usually this means that the HDD has failed or the program that loads up windows Vista is Broken. Your computer may not be detecting your Hard Drive and that's why its not detecting any issues (No Hard Drive no problem...!) |
1st step is on a dell tap F8 when the computer is starting and there should be an option for repairing your computer run this and see if it detects problems. Be careful in here because it does give you the option of reinstalling your OS.
2nd go into the BIOS (Basic Input / Output System) This will load even if there is no OS on it. I believe on a dell its F2 key, look for messages that say "startup Press F? Key" Check the Boot devices in there and see if your Hard Drive is listed. If its not we know that the drive or port the drive plugs into has failed.
Lastly if nothing else works we can still retrieve data off of it using an alternate method, this is going to be tricky but using an alternative Linux OS we can at least gain access to the drive (Under certain circumstances) Download a copy of Ubuntu http://www.ubuntu.com/ burn an ISO to the a CD ( Just research burning ISO's online, the ubuntu site should have that info). In the BIOS set the boot order to CD first. pop in disk and select try ubuntu. This will allow you to access all files on your computer. (I CANNOT STRESS THIS ENOUGH THIS WILL NOT FIX YOUR COMPUTER JUST GIVE YOU ACCESS TO DATA!!!)
