Lifehacker’s Rick Broida show you how to replace a dead power supply in a PC, he writes –

“Power supplies die. You never know when it’s going to happen, but it’s always at the worst possible time. You hit the power button and your PC just sits there. Idle. Quiet. Dead. At least hard drives have the courtesy to make that wrenching death-rattle when the end is near. But not power supplies: They just give up the ghost. Poof.

Fortunately, it’s not impossible to replace one on your own. It’s tricky, yes, and a bit time-consuming, but it’s something any self-respecting lifehacker should learn to do. Plus, it’ll save you upwards of $100 at the local computer shop, and that’s always a good thing.

Here’s how to extract and replace a power supply and, in the process, resurrect your fallen PC.”Link.
