Well, it's the third time I've blown a fuse trying to fix my PC I made. Any ideas on how to stop this? Alternate power? Answered

I took apart an old PC, salvaged each and every piece, now I'm trying to put it all back together again. I finally managed to make (what I think should be) a PC... But I turn it on, and the little red-light on the motherboard goes on, but the screen says "No signal", soooo I fiddle with some wires, turn it back on, and "POOOF! DIRRRrrrr...." Blown a fuse, the whole house is dead. My family screams in annoyance because it's the third time I've done it ;-) So any ideas on how to stop this? Maybe an alternate-power generator (Not that I have one, mind you)?

you have a problem with the power supply dont experiment with it connected to the computer - you can damage it. instead take it out and experiment only with it. to power up conect together the green wire and a black wire in the big connector is the voltage switch on the power supply in the correct place ? is the switch bad ? in countries with 240 V disconnect and isolate the 2 wires that go to it is the power supply ok inside ? i recommend to use the computer with a known good power supply and not this one. (even if you fixed it and it works it might get damaged and may damage the computer later)

Start small and build up. Plug only the PSU in and see if it works. Then plug that into the most-stripped-down mainboard and see if that works. Keep going until you find out which bit is causing the problem and replace it. "I fiddle with some wires" worries me - what exactly were you doing? L

I was just fiddling, no idea what I was doing :D - it was the power that was faulty in the end

Your PSU is knackered? You need a new one, and it's best to use a PC PSU rather than anything else. L

If its blowing a breaker, then the Power supply is bad. Don't use it, and hope you it hasn't destroyed the rest of the PC.
