PC Doctor? My puta is dead!
My reasonably new (5-6 year old) PC that doesn’t get used a lot but is useful for working on has decided to stop working. When you turn it on it makes a few whirs and clicks and switches the monitor on but then the monitor times out and switches off. I don’t even get the slightest bit of loading/start up happening.
I’ve opened it up and had a look to check connections of the various components and reseated things but it has made no difference.
I need to get a boot disc sorted to see if I can fire it up that way but I would appreciate any pointers on what to try to see if I can identify the fault and fix it. Or some steps to eliminate different problems?

Could be a few things but as above, PSU is a good bet.
Before swapping it out it’s worth disconnecting everything from the PSU except the motherboard (and grapics card if it has a seperate power feed).
Also worth blowing any dust out of the PSU and off the board.
Power up again and see if you get any further. If so, plug things back in one at a time and see when it stops powering up.
Either the last component is pulling the PSU down by drawing too much power ot the PSU isn’t able to put out enough power any more (so, faulty).
If you get no joy with just motherboard connected then I’d guess the PSU to be at fault.
I assume you’re not getting any beeps or flashing error lights from the BIOS btw?

No beeps at all.
Removed graphics card, wireless modem and then the soundcard noticing that the lead that connects from soundcard to motherboard had broken a couple of wires that were touching the bottom of the case.
Swapped leads round and booted up straight away 🙂
Just need a new lead for a few pence!Posted 4 years agoPJM1974Member
That’s only one step up from a stone tablet and a chisel these days…
There’s a rubber keyed ZX Spectrum in this house that still works just fine, a week or so shy of it’s thirtieth birthday. Excel is a tad slow though.
PSU is the likeliest suspect here, followed by the motherboard.Posted 4 years agotoys19Member
This still sounds like PSU, as they fail they make less power, so it will boot without any cards etc but as you add them the PSU falls over.
I use 4x high power PC’s for my business, and always keep a spare PSU as failure is so common…
You can get a cheap PSU from maplin or elsewhere mail order. Try it, if that doesn’t work, pack it up carefully and return “un-used..” or keep as a spare..
A less Machiavellian way is to take the PSU out and test it on another machine.Posted 4 years ago
