During boot-up upon seeing any text display hit the F8 key to try to get into "safe mode" boot. If it can do that then you fiddle around later and no white display then possibitlity a driver problem. Next, upon reboot it repeats the white display then you need to correct the problem, maybe return to date using the "restore point" feature to when it didn't have such a problem. -OR- make a Linux bootable CD disc. Create one using the available .ISO file, burn to disc using the proper burn method in order to make it bootable. Once done and bootable, mount in your laptop and assure that the 1st boot device is the CD/DVD drive, try to boot. If during that process it seems to display correctly and just works, then again some driver or win7 OS issue. If none of this works and the white display appears no matter what you do, then you have a physical bad h/s issue. As already stated by you it could be bad or loose wiring or the mtrbd, itself. In most cases its best to sent to repair or check for costs. Also, a white screen may not be actually blank it maybe a "washed out" screen doing the reverse as you can't see white text due to it being flooded white. Thus, see if it actually seems to boot-up or activity of same, the HD led blinks away, etc., or place a bootable disc in CD/DVD drive. You can vist the Dell support website forum and see what users are reporting on same problem. if many 1014 users are having the same issue, possible h/w fault.
