Today while i was watching a youtube video my pc just crashed and restarted a bunch of times then, when i power it on it restarts after about 3 seconds and it will just run like that with no dvi signal coming up on the monitor. So i tried unplugging and removing components from my computer to try and isolate the issue but have had no luck with fixing it so far, but when i took everything out of the system except the PSU and CPU i still had the issue which leads me to believe its either the motherboard, cpu or psu also there was not any beeps either when i had removed the ram which was a little odd, here are my system specs

-ASrock z87 extreme 4 motherboard
-i7 4770k cpu
-nvidia gtx 550ti (just a replacement from my 780 which was defective)
-xfx 850 watt fully modular 80+ gold rated PSU
-2x 8gb crucial ballistix ram @ 1600mhz
-240gb crucial ssd
-2tb seagate 7200 rpm storage drive
any info/help is much appreciated
