resurrect a smoker's motherboard

A chainsmoker friend who used to be a PC techie but got seriously throttled by radical vision loss had another PC quit 9 months ago. I had build it for him about 5 years earlier using an Asus socket FM2+ motherboard with onboard VGA, DVI, HDMI and DisplayPort outputs that his son bought him from TigerDirect. Before the new motherboard, CPU, PS and RAM were bought in January I had tried cleaning the A88X chipset motherboard with a modest amount of DeoxIT Brand contact cleaner/wash, which didn't solve the complete POST failure. Today I finally found the magic after closer inspection of the remaining tar and dust goo buildup near RAM and CPU sockets. After buying a compatible CPU to test with that didn't change anything, I used the rest of the can, which wasn't much, and didn't come out under much pressure. It didn't help. Then I tried 2/3 can of Techspray IP electronics cleaner that comes out in force, then blowing it off with compressed air, then baking it half an hour @200F. It worked. Board now boots using either his original A10 CPU or the A8 I just bought. :)
