Re: hp probook 4310s power off before booting to window
Is this a new problem? What was the last thing you did before this happened?
Plug in the Windows 7 disk that came with the computer into the CD drive. Then boot off of the CD to run Windows Repair.
I recommend these:
Windows 7, Office 2010, Photoshop CS6, IE10
Security Essentials, Asus, Dell, Samsung,
Intel, NVidia, Xbox One, Android, Gigabyte
