i was measuring dimensions in my computer because i plan on making building a custom case and i didnt think to turn it off. i was using a plastic ruler but for this one part i was using a (metal...) tape measure. i just touched a couple leads on the back of my video card (9800gt) and it smoked and then my screen turned off. i quickly hard powered down my computer and unplugged it immediately. do you think i can turn it on? did i mess it up for good or just for a second? any help would be great.
