Hey guys,

My PC won't turn on so I disassembled it and found this on my motherboard. Could this be the cause of it? Thanks.

unfortunately I'm limited by my phone, so can't actually see the picture you have posted.

Firstly, if the board is too far gone then its going to need a pro to look at it, examine the damage, then do the necessary in those areas.

However, you can occasionally revive a dead board by simply dislodging some of the corrosion if that corrosion is for example creating a short..... the easiest way to do this is with an ultrasonic cleaner. Decent cleaners use a sweeping frequency to make sure they clean everything up nicely. using a pcb cleaning fluid along with distilled water will help, as will using it warm (about 65 celsius). after that, soak in 99.9% isopropyl alcohol to displace the water, and allow to dry. give it a whirl you might be...
Do you live by the ocean or in a very humid climate? The rust would certainly damage the mobo, assuming you purchased the computer brand new and has rusted over the years. Some silica packs in your case can help to absorb moisture.
 


Nope. But last time my friend used it for video playback at a beach. I really don't use this PC that much. But now I wanted it to serve as a backup system but this happened. Is there a way to remove this rust and power this PC on again? Thanks
 
I have asked my friend that work in this field. He said some heatgun treatment would fix it, easy. Meaning, you had to repair it at some service center that has proper equipment.

Still, I say there are plenty other factor that can cause your PC fails to start. The first on my list is your PSU. Next one is the power cable. Then the GPU.
Those are the big 3 culprit most of the time. If those 3 turns out to be okay, then everything else considered.
 


I'll check if the RAM,graphics card, all the cables and the PSU are still working. Thanks.

Update: Everything mentioned above is working. So i'm suspecting the mobo is broken.

If this doesn't work, your going to need to send it to someone that knows what they're doing, and has a decent micorosoldering and reworking setup.
