computer won't start help

thanks and no there is no lights on at all i might give that a go ut my cousin is a computer tech so i might get him to replace it

also if i told you the computer type would you know coz it is pre build from the factory

i found ac input 220-240 vac 2A 50hz would that be it i found it below the power supply on the outside

That is the voltage set to run your computer - you have 220v there?

You're wanting to spec the wattage of your PSU to decide whether to replace it with identical model or up the voltage some. You need the model number and watts either by finding the specifications for your computer model online or looking more closely at the PSU until you find it.

Or you can take it to a shop if you're not confident you can replace it yourself. Ask them the benefits of increasing the power, as some machines are underpowered and this can cause PSU loss.

If you are confident enough to do it yourself, these questions can be asked here or in the Hardware forum once you have the specs for your current PSU, and good advice can be given for what to replace it with.

thanks i took it to a friend to fix it he runs a business and he has to get it off ebay coz he does not
have psu with that power so it will cost me 180 euro to replace it i hope since it costs that much it will be long life

what is the advantages of increasing the power on the psu

A power supply that isn't working very hard lasts longer and produces less heat than one that is running close to its capacity, plus you'll have power to spare for expansion (better graphics card, extra hard drives, sound card, etc)
180 euro is a ridiculously high price for a power supply by the way. You should be able to get one for about 1/3 to 1/2 that price.
