DId this just suddenly start, or have you change anything recently such as updating/reinstallling Windows or added RAM etc?

 

Can you boot to safe mode by holding down F8 while turning on the System?

 

Have you tried re-setting the BIOS to Startup Defaults?

 

Do you have a Windows 7 System Repair Disk, or can you create one on another Windows 7/8/10 computer?    

Note:  If you computer was running the 64-bit version of 7, the Windows 7, 8 or 10 computer you make the CD must also be running a 64-bit OS as well

 

 See Backup and Restore the Control Panel to create the System Repair Disk.    Requires one CD-R

 

If so, you can boot to the Windows 7 System Repair Disk and run System Restore, or Automatic Repair from there
