Hi,



What do you mean by "all the main voltage"? I checked all mosfets on motherboard and they produce proper voltage levels (according to boardview file). Majority of mosfets generates 1.5V, 3V or 5V. As I mentioned in my first post, NB and SB power rails are also present. Are there more power rails that I must check?



Unfortunately my diagnostic card has no RESET LED. It has 3 LEDs, but they show voltage levels... i guess... they are always on (even if I put the card into my good motherboard).

My 7 year old AM3+ motherboard has broken overnight. It powers on, but does not boot (no picture, no beeps). I checked RAM, CPU (with another AM3+ board), PSU - all components works properly so it is a motherboard fault.

What I've already checked:[LIST][*] no short on main power rails[*] no shorted mosfets[*] BIOS chip works (I could read its content with a programmer)[*] RTC running (it consumes ~4µA from the battery)[*] CPU and chipsets (NB / SB) are getting warm after power on motherboard[*] CPU voltage (vCore) is ~0.84V and motherboard does not adjust voltage[*] chipsets (NB...
