You need to connect to iTunes via your computer & select restore this iPhone. This will re install iOS & should solve any problems you have. You will lose anything that is currently installed however, so, if you have a backup on your computer, once the iOS has been restored, you then need to go to restore from backup. This should then put your iPhone back to how it was when you last did a backup.

well. be sure the power is plugged in

then pull the battery out of the laptop

press the power button down

look at the little lights indicating power on .. battery charging and hard drive activity

if the power light comes on..

then the screen is the problem

if the hard drive comes on after say 10 seconds

it is definitely the screen



put the battery back in.. be sure it is in solid

put the power pack in the wall

if the battery charge light comes on

then the power is to the laptop and battery connections are good

so the laptop may have overheated...

wait five minutes

try to power it on again

if the fan does not power on...

it has a bad fan...

quietly set it where ya got it from then

that sounds like a corrupted hard drive...not 100% sure. u can try formatting your hard drive.

The file errors and cross linked files are indicative if a failing hard drive. You are going to need to replace the hard drive.

This sounds like a hard drive failure. You can press f8 to enter safe mode with networking during post. If it boots to windows,then go online & download the video driver from nvidia,install it & reboot. If that doesn't work,try re-formatting. If it won't do that then try a new hard drive. I have the software needed to test the hard drive,but it's for commercial use only. This is the back yard method.

Sounds like the hard dribver may be bad. Their are site to download software that wil check a hard driver without windows,just for a disk.  Try:  seagate.com  for seatools, for example to check the hard drive. The other possibility is that the gray flat cable is upside down or damaged or that the cable socket is. Another thought . You do have the hard driver turned on in the BIOS setup screen,corrct. In other words, this is somethng that just hapened to a working computer w/o any changes made by you.  

Hello. Try a different hard drive. I have only seen a couple machines do this, but replacing the hard drive fixed it both times. Thanks!

Are you able to adjust the contrast or brightness? Try to turn them down to about 50%.
