PC won't boot

[FSKJADOON]

I just updated my PC from Windows 7 to windows 10 this week and everything was fine until I shut it down and turned it on the next day, it keeps on turning on and off and eventually when it's on while booting the monitor loses display signal and the mouse and keyboard lose control too.

Please help me fix this.

PC Specs:
Intel i5 3470
8gb ddr3
500gb HDD
Nvidia geforce GTX 670
