Well sorry i'm a forum noob and new to tom's hardware, I recently upgraded my computer and changed my processor, motherboard, ram, and PSU. My processor is I7-3770k, my motherboard is P8Z77-V, RAM is Corsair Vengeance 1866 CAS 9, and PSU is Corsair TX850. I have two problems. One, no display. Two when I start up the pc, it shuts off briefly after I start 5-10 seconds, then restarts on it's own and starts and stays started up for good.
