Pc not posting

I turned on my computer yesterday and it wouldnt post. I have made no changes it was fine the day before.

I unplugged all drives, devices etc and tried just with the mainboard, ram, cpu and video card and still not a beep. I tried using just one stick of ram and reset the cmos with the jumper and then the battery and still nothing. All the fans are working, power on etc , just no normal beep beep at startup. I cant hear if the hard drive is spinning but am I right in thinking it should post without this connected ?

I think it must be the mainboard or cpu but I have no way of testing these. I usually manage to sort out my own problems by googling using forums etc but I dont know how to test the mainboard or cpu and they wont fit in my other computer.

There is one computer shop near me , I was hoping there would be some kind of way to test the cpu and mainboard but the man on the phone didnt even know what Power On Self Test was so there was no way I would take my pride and joy into him. He just kept saying they would test them with software ?

The computer is 13 months old just out of warranty and I bought it from Komplett in Holland , I live in the UK so I do not want to send it back . My boyfriend wants to just buy a new mainboard cpu and memory but I dont want to spend his money if I can just replace one part.

I bought and fitted a new power supply 4 weeks ago, a corsair TS650W ( Just the fan on my old power supply had died). Do you think there is any chance that the new power supply is faulty and has fried my mainboard ? Is there anyway to get a power supply tested in a shop with some kind of meter ? I wouldnt want to buy a new mainboard and have that fry to.

Does anyone have any suggestions or things I could try, or can you tell me if a good repair shop should be able to test the mainboard ,cpu and power supply and how they would do it , maybe I can phone round some other places and know what to ask for.

Any advice or suggestions would be great. Im lost without my computer and am just staring into the case hoping something will happen :)

Should post without HDD and give error message "no system disk" or simular.

Yes its possibly the things you mentioned CPU - motherboard.

Faulty memory or video should give error beeps.

Even though fans run, most likely suspect is the power supply unit (PSU) and cheapest easiest component to renew.

If you have another Pc available I would be tempted to try plugging in another PSU first.

PSU Tester from Maplins click here

Order code A48GF in case the link doesn't work.

You can get them cheaper from QuietPC (I think) but the site's down at the moment.

Thank you both , I have tried another power supply in it and the problem is the same, so I will buy a new board ,cpu and memory. I think I will go for quad core.

The power supply tester is just what I am looking for, my corsair was £90 odd quid and seems a shame to chuck it , if there is nothing wrong.

:) cheers chaps

I have an old PC that earlier in the week was working perfectly OK and then when switching on it did not post, it did not do anything at all.

I took the battery out of the motherboard for a few seconds and I was away again all OK.
That was more luck than judgement but I just throw it in for what its worth.
