INPIRON DESKTOP 530 WOULDN'T START

Did you have this incompetency problem when you were in your 90's?

Hello KUKE1 and welcome to Tom's Hardware Forums. Badge is older than he looks   so don't worry about hiding your age.

Can we have some more details, please? Is there any sign of life in your Inspiron at all? Do any lights show when you switch on or are there any sounds from within? Start with the fuse to the main electric supply and work you way round from there. If it's totally dead, do you have another computer you could borrow the power supply uniit from? If not, they aren't too expensive to buy.

I have a computer repair business
MANY Inspiron 530 come in with bad power supply
light on PSU will be on
push the power button and the motherboard light is on
but no power to system

go to ebay search "inspiron 530" and find a top rated seller
try to get the upgraded 350w PSU
they had two models of the 530 a Core2Duo and a Core2Quad
and the PSU from the Core2Quad is the one you want

if those symptoms are what is happening to you OP
then it is definitly power supply
cost about 30 USD on US Ebay
