Peculiar motherboard malfunction...
- Thread starter Grall
- Start date
Now it's my turn.
My motherboard turns on but nothing is displayed. This power-on may occur instantly or after a 5-10 seconds delay from when I press the power button. Holding the power button a few seconds to shut it off won't work, now will restarting it.
All i did is removed the old heat-sink for my southbridge (an nf4ultra
) and cleaned the area with something that 96% alcohol. Then installed a new one.
Since there's little chance that switching the heatsink did damage and considering the symptoms I would blame the PSU on this one. What do you think, guys?

Grall, I'm almost certain your mobo have wonky soldering point/points or bad trace on PCB.
If you can't test PSU theory first, then try this:
- take your computer components out of case (less strain on PCB).
- if you're using 3rd party CPU cooling, take it off and run Radiator without mounting (THIS IS NOT SAFE!)
- try different memory slots / just one DIMM
- when all above fails to make a difference, let everything cool down and then using hair dryer on hottest setting warm up whole mobo nicely till it's hot to touch, then power on
In case none of above helped my theory is wrong
I had lovely ASUS CH IV F with bad traces from CPU socket to memory. My computer would randomly crash or slow down and crash usually in the first 30 minutes of usage. With time it got worse but I had to bear with this for 14 months because obviously 1st RMA came back with 'nothing wrong' result. In the end my mobo quite often couldn't POST until I touched CPU block or loosened mounting. To get this problem past RMA I videoed this behavior and then it only took ASUS 4 months to get back to me with replacement!
My sympathies and wish you good luck!!!

I've tested with a spare and it looks like the PSU is fine. So the motherboard is dieing (is already more than half dead, ofc).
Funny thing is I pressed the power button and nothing and then started doing things in my apartment, talked to smbd at the phone for tens of minutes and while at it, the fans started spinning just like that without any warning. It was more than an hour delay in powering on. Of course, maybe the power button pressing wasn't the cause for the spinning fans and instead the mb powers up whenever it wants.
So, I guess I'll start building shopping for new parts although it will be difficult since it's just about time to adjust my "unlimited spending policy" for hardware (i.e. grow up); and will be hard to make(or not to make) compromises.

Lightman, thanks for your nice post. Scary hearing about your 4-month RMA turnaround, but I have a pretty good relationship with the store where I bought the system. I'm gonna do a clean Win7 install on a spare HDD and install relevant drivers and so on, then run something that loads the GPUs and see if it wonks out (pretty sure it will).
If it does, I'll take the whole PC back to the store, let them check it out and handle warranty stuff for me. If it doesn't, I'll scratch my head in confusion, then re-install Win7 to my primary SSD drive in just the same manner and hope things are now normal...
