The problem I am having is with a new rig I was putting together. When I start the computer it keeps on going on and off without even actually starting. The fans startup and shutdown but I can't even get to bios. Its as if the computer gets just enough power to initialize the hardware and then it runs out. At some times it manages to bootup but after a while it freezes and there appears red and green dots/lines all over the screen in varying numbers every time.
Of the new rig the mobo (asrock z77 pro), the cpu (intel i5 2500k) and memory (kingston 2x4gb) are new and the rest come from my old comp.
Now my asumption is that something is overheating but as I have no external way to monitor the comp temps I don't know which one. One possibility I am leaning on is the power supply failure. Unfortunately I have no spare parts which so swap around to test this theory. I need someone with larger experience than my own to either confirm my theories or give me their own. I know it is difficult to judge without seeing the thing in action for ones own eyes but any help is appreciated.
