Hey there, @steve518!

 

What kind of diagnostics did you run on it? Was it just chkdsk? 

I'd suggest to boot from the Windows installation disk and choose Repair, afterwards open the Command prompt window

And type these commands: 

 bootrec.exe /fixmbr

 bootrec.exe /fixboot

 bootrec.exe /rebuildcd

Afterwards just reboot and hopefully the problem will go away.

 

You can also try this simple thing, that usually works for new laptops' startup errors:

Unplug the power and take off the battery for fifteen minutes, then connect it again and leave it for another 15 minutes or so before you try to restart.

 

If these doesn't help, I'd suggest you contact the store you bought it from.

 

Hope it works though. Good luck!
