Elecrical shorting noise

johnjewitt2004 · 28 Feb 2016 at 05:33

This has baffled me for months, I have a newish computer and every now and again I hear a type of electrical sizzling shorting noise coming from around the back of the computer, the noise normally lasts around 2-5 seconds and sometimes even trips the consumer unit (fuse box), I've tried changing plugs, extensions etc so I thought it must be the power supply, I bought a new power supply that also cam with a new lead and the problem still continues and is just totally random when it happens. Anyone have any ideas before it blows up, lol, any help would be appreciated, thanks

Is it connected directly to a wall socket? Also try different one.

What is your PSU brand and rating and what is your graphic card?

Is it modular and if so have you replaced old cables within your PC by new ones that came with your PSU?

Thanks for the reply, the psu is an Aerocool Integrator 500W, the graphics card is shown in the picture, I am busy trying a different wall socket altogether. Also if you look at the pictures the voltages are all messed up and it was like that with the other psu also, could it be related to the motherboard.

Just looked and I thought I could insert pics, anyway of getting the pics to you, thanks

OK, what 'new' power supply and what kind of GPU. Was it another Aerocool or equivalent cheap junk stuff? How many PCI-E connector required on GPU?

Also, could be a poorly grounded mains in you house, now, that's be kinda bad. Try another plug.

Could be a short with the case. If you want, you can move the components outside the case. Will make it much easier to isolate the noise source. GPU coil whine? PSU? Motherboard?

The fact that your computer regularly trips your fuse box should really be a concern, and not something to take lightly. PSU's, even that one, have all kinds of protections, and should not affect anything outside the computer. Basically, to prevent that kind of stuff, and you know, like fuse boxes, house fires.

Keep that machine unplugged when not around. At least, that's what i'd do.
