Hi all, this is my first post and im not new to forum What i like on this forum is that many advanced/pro users know real causes and never try to assume that symptoms of fault is in user, for eg : "did you try to plug power chord" and similar idiot "im trying to be smart" assumption we all see on many of well known forums.
Let me go straight to the topic:
I got Asus P8Z68 deluxe mobo which sudenly stop working (according to past owner), when PSU is plugged in, power button glow red and reset green, when i press pwr button, nothing happend, only thing that happen (except this onboard leds) is that northbridge is geting hot so i assume that problem is with NB chip/power lines to it, as NB shouldnt be warming when pc is off.
I tried to short green-black psu lines while sitting on mobo and then it start (fan spin, red lights showing problem with cpu,memory,pci-e) for like ~20 seconds before shutdown. Another thing to mention Q-led is not turning on. Another thing to say, i tried every posible scenario (with/without mem,vga, 12v cpu rails, checking 1155 pins, reset bios etc) and nothing happend, power button is always red,no fan spining,northbridge is getting hot.
Is problem in northbridge? What to check and which vrm belongs to NB, its maybe faulty mosfet,cap or so, related to it? One more thing to say, many capacitors on mobo looks like little bent and not sitting properly on surface, is it posible that some of them failed even they are polymer caps? Any advices will help me troubleshoot this mobo, thanx in advance!
