It's exactly as simple as you describe. Do double-check the power button is connected first though!
Right then, cleaning is done!
Just took the side off the computer again, all capaciters are fine, no doming or brownstuff coming out, all nice and shiny metal tops
The switch cable is in, i pulled it out, then pushed it back in again and still nothing, took the leads off and held my screwdrivr between the 2 pins and nothing.
So is this obvious signs it is the power supply?
When i called the computer shop up and he said £55-£60 fitted, i asked him what happens for it to be that much when the power supply is only £20. He said they check everything, give it a brush out and fit the part, but ive already brushed it out(not much dust in there anyway, and didnt touch the main board but that isnt dusty. Everything else seems fine, its just the computer wont turn on.
Ill talk to my parents more about it when they get home, but im happy to fit one. It looks simple and straight forward, so i cant see the point in taking it to the computer shop, leaving it there and waiting for it to be done, when we could just go and get a power supply and have my fit it.
I take it the connectors are all the same, or different enough that you cant put one wire into the wrong thing, like putting a power wire tothe CD re-writer to something else? Or is there just one/a few plugs that going into the PSU?
Cheers
