I has to swap PCs with grandma, and now I got her old crap she had. Now, when the mobo is powered, it gives out a somewhat low-pitched noise (coming from around the ethernet port). If I plug in the ethernet cable, the noise gets high-pitched, and it just kills my ears. It's a very, very old VIA (probably ASUS) motherboard. Edit: also, the integrated graphics regarding to grandma's über-super CRT monitor, if it's idle, the refreshrate goes to a few *kilohertz*!
