If you don't like the "blow repair" I'd rather suggest a can of compressed air as the next attempt ;)

Compressed air is my preferred choice but it's a little spendy for what it is.

When I worked in SGS, now

When I worked in SGS, now STMicroelectronics, I ws amazed to see technicians using hairdryers on printed cicuit boards they were testing and repairing. They told me that if you heat a microchip and the board crashes on a monitor, then you simply substitute the chip and all will work again. Amazing.

People also have used a can of Freezit spray to cool individual chips, also as a means of finding weak or marginal ones which might be worth replacing.

I know that if you have a bad hard disk and you put in the fridge (not the freezer) you may be able to read it.

While this is not for the

While this is not for the faint of heart, I clean boards by pouring isopropyl alcohol (at least 70% concentration) over them. At that level, there is enough alcohol to get rid of the water too when it evaporates, though a 91% concentration might be safer. And a 50% concentration is too low I have found; you don't want the water to migrate through the leads into the chips or remain in the coils, etc. Then dry the card with a blow-dryer. I would only use low heat however; the high heat can get very hot and might damage a component.

The truly brave clean

The truly brave clean populated PC boards by putting them in a dishwasher.

No, I have not done this.

No, I do not recommend this.

I don't recall whether they use detergent or just let the water do the job, or even some other additive.

I have cooked Apple logic

I have cooked Apple logic boards and GPUs in my oven to re-flow cracked solder and repair connections.

Contact cleaner is good for cleaning gunk off old motherboards:

Having 11 PCs and living in a

Having 11 PCs and living in a dusty environment the best purchase I have made was this DataVac. It is a blower not a vacuum.

The white part is metal, it is very heavy duty, it has a removable filter in the bottom and a couple of attachments. It is powerful enough to blow the leaves off the porch. Cleans out a PC in no time. Have had mine since 2011. Love it.

I was going to post a video of someone doing this. Then I saw there were many on Youtube. That made me wonder how frequently this ruined the boards, so I did a Google search for "I destroyed my motherboard" (no quotes). And I found the strangest thing, multiple threads started by people who WANTED to destroy their motherboards without harming the rest of the PC. Their schemes seemed to have the common theme of "I want a new motherboard, but the people with the money won't buy me one while this one is still working." Example:
