The title got you here, admit it. 
Anyway, here's the issue.
I keep getting random 'static' or 'noise' on my monitor. Naturally, since it's a cheap monitor, I assumed it was the monitor. Instead, I think it may be more disappointing. You see, I installed my own PSU and video card both at the same time, and those were the first PC components I ever installed, so there's a high chance of error. I don't think the fault lies with the vga monitor because when I turn it off and then back on nothing changes, but tapping on the case of my PC clears the static temporarily. Sooo... ****. What loose cable should I be looking for? One from the PSU to somewhere, or the PCI-E connection, or what? No power cord connects to my GTX 460, that's apparently handled through the PCI-E 16x connection. Is it a failing video card, do you think? This really isn't an old one. Could it be because it's factory overclocked? I'm fumbling in the dark here, and I'd appreciate help.
