Someone sold me a Dell Studio XPS motherboard and I really wanted to get the thing running. After installing all my components and turning it on it started making a weird noise and I could smell smoke coming from inside the case. I quickly unplugged my PC and removed the mobo to find that one of the 4 nuts on the back rubbed against the wiring embedded in the mobo. Is there a way to repair it? If so, what would the price be to fix it? The wire is still there but is severed in two.
