Windows 7 was buggy, so I decided to clean (inside) the computer, reinstall Windows, if not help, carry it in for repair. What is the essence of the glitch: when the computer is loaded, it is tight, earlier in games textures were lagged, but then it got worse. In general, the installation was finished (with usb), the last stage, and now windows 7 was loaded and wrote:
The computer has unexpectedly rebooted or an unexpected error has occurred.
I shake about.
Installation will continue after a reboot.
But after rebooting again he writes an error, again I press ok, and so on in a circle! In safe mode it hangs on
The program loads services
What to do?
