So I've just started having an issue with my pc randomly black screening and gpu fan increasing to 100. I believe this to be the psu which i just replaced today(about 4 weeks ago I replaced my 750 ti with a 1060 and the psu I had in it was a generic psu I know this is bad). Then I saw this grease/oil substance under my vrm. This wasn't there when I replaced my gpu 4 weeks ago. And I was hoping if from these pics if anyone can tell me if this harmless suspension fluid or something from the heat sink or from a leaking capacitor.
