I was cleaning my pc when I spotted a oily surface on my motherboard. I took out the motherboard and as a soon as I turned it around I saw two large spots of oil or oily residew in the vrms area. I have a msi 970 motherboard and I haven't done any over clocking to my fx 8350 or ram. I took off the heatsink of the vrms and found that the bottom of it where it is in contact with the vrms is really oily and shiny. Why is this a thing and is it bad? If so how can I either fix it or should I just get a new motherboard?
