My pc is a Dell 4600 and the OS is windows 7 Professional. I now seem to get an error whenever it reboots that it wants to reboot in safe mode, etc. Whenever I click on the normal mode, it goes into a loop with the same options. At one point I had to repair windows 7 and it said that it would restart the pc several times,. After I have selected the boot options and after windows starts, after the logo screen I get the screen to say that "There was a problem, etc. etc. and I am back to the normal choice of boot options. I am still not back to normal yet. i.e. I still get the same options to select the type of boot option, safe, normal etc. and it goes into a perpetual loop. Can someone help on how to resolve this. thank u.
