PC wont start & 2 chipset on Motherboard are heating excessively

[Ibrahim699]

My PC suddenly stop working.
Then when I tried to restart it (by reset button) it didn't give any Display. (CPU fan & other fans started)
Then again I tried to restart it now this time even CPU fans wont start( but green light on motherboard lights up ).
Than I tried,
Disassemble and reassemble... didn't work
Changing the RAM... didn't work
Changing PSU... didn't work
Reseting BIOS (By removing battery)... didn't work
Reseting BIOS (By removing jumper)... didn't work

I have notice extreme heating on 2 chipset of motherboard (for which I have attached a picture of by highlighting it)
And those chipset start heating even if dont press the power button on cabinet... As soon as I switch on the power supply (power line from switch board to PSU) it starts heating up...


config....
ASUS M5A78L-M LX V2
AMD FX 4100
CROSAIR 4GB RAM
WD 500GB

just confirming...
with the PC turned off, but plugged in, those chips overheat?
that's not good obviously and would indicate you mobo is faulty.


when you say excessive heat, are we talking toasty warm or fry-an-egg hot?

Does the keyboard num lock light come on?

If not, what test equipment do your have?

[Ibrahim699]

@Mark.
Yes... even if I just ON the switch board button...

I wasn't able to measure its extend of heat as I got scared... Because within seconds it reach to a piont where i could not touch the chipset... And still the heating of the chipset was increasing..
It was giving the ironing smell.. (the smell which comes from iron when it is heated)

[Mark.]

yep, I know that smell, it's closely followed by the magical white smoke escaping from the chip, never to be put back in.
if the chips got that hot, there is an excellent chance that they have been fried.

@Geek-9pm

Nope it does not...
I have just another working PC for testing (that is how I came to know that motherboard is having issue) no other special equipment for testing

You could always buy a new motherboard and if your lucky that swap will fix the issue. I'm curious if your have a bad power supply that over voltaged your board. What make/model power supply do you have in this system?

1.  but green light on motherboard lights up.
2.  I have notice extreme heating on 2 chipset of motherboard (for which I have attached a picture of by highlighting it)
And those chipset start heating even if dont press the power button on cabinet... As soon as I switch on the power supply (power line from switch board to PSU) it starts heating up...

1.  Only indicates 5VDC Standby is on.
2.  Motherboard is dead.  One of those chips failed & took the other with it.
