PC keeps rebooting

[iReZar]

Hi everyone,
My PC keeps rebooting on its own, my monitor says there is no signal. I can't get into the bios. I have tried to clear the CMOS, but it didn't work.

My pc:

Mobo: MSI Z77-GD55
CPU: Intel I5-3570K
GPU: MSI GTX-660TI PE
PSU: Corsair Enthousiast TX850 V2
RAM: Kingston HyperX KHX1600C9D3B1K2/8GX

Hope you guys can help me out, I don't know what to do.

I Also tried removing 1 RAM stick, but that didn't work either

Mate the only way is to start disconnecting things, have you got some spare parts to work with, if so, take the video card out and put another in, take one ram out then the other. Also did you change the bios setting to overclock. To get into the bios boot it and keep pressing the del, F2, F12 and F1 buttons one of them will get you into the bios. Set it to defaults. If I had to guess I'd say video card.
