hi, I have a problem for a few days now, when I start up my computer, it starts normally (logo screen, detecting hdd, etc) but makes a sissing sound, coming from the PSU`s fan (i think). within the first 30-40 seconds, it shuts down. It does so the first time, and sometimes the second time I try starting it, the third shot is always the lucky one anyway, if it gets passed the logon screen the sissing sound stops, after a few minutes. does anyone know why is it doing this?
I would check it is coming from the psu and if it is then it's time to buy a new psu before it fries your innards
