To do a bit of volt modding, i read you can get copper putty-like grease/paste which sounds quite good, otherwise where would i buy conductive material such as silver paint or a pen or the like, cheap as pos..?
I've done this but it's unstable to do so and not worth it. The computer actually runs unstable and slower due it not functioning correctly. I'm also assuming that your board doesn't have voltage control. Your just going to have to buy another one or leave it as it is.
But if you want to try it, just google conductive pen.
