How do i know my cpu is dead


My computer just died turned itself off.

I can't turnt it on again, not even the PSU fans spin. If I turn the swith on back of my PSU into off position then after two seconds I can hear quiet "cvak" from the PSU. If I turn the PSU on again and try to turn on the computer only what happens is the blue diode on CPU fan "blink" then I hear "cvak" again and thats it.

If I disconet the 4Pin connector from the MB (I think it feeds CPU) and turnt off the switch on back of the PSU wait until the "cvak" turnt on the PSU and turn on the PC than the fan on PSU starts and the CPU cooler starts spining, but if I connect the 4pin back into the MB it all dies in a second even the PSU fan doesnt spin anymore.

I do work with computer all my life and I never seen nothing like that. I think it's PSU (cheap noname crap for 15$) ...or maybe it's MB MSI 880g e41

  1. Replace psu.
  2. A different explanation might by something to do with one of your RAM slots/RAM stopped working
  3. Hi I've just replaced PSU for a new one from XFX and it still same just without the silent "cvak". I have disconected RAMs. It's only psu MOBO CPU
    Even without RAMs the fan should start spining (and it starts if I disconect the PCI or CPU or what is it cable)
  4. I have no idea what you mean when you say "cvak"...check your motherboard for any bulged, discolored or leaking capacitors or burnt chips.
