Title: PC Not working
Post by: chrisdicko on November 16, 2007, 11:51:54 AM
My friends PC aint working......

It turns on, but there arent any beeps like there normally is at post. All the fans spin etc. Ive tried resetting the CMOS, and disconnecting everthing except the GFX card, Ive also tried changing the RAM etc around and completely removing it. But none of this has worked. Any ideas??

take everything off of the mobo (ram/cpu/gf/hdd etc) so that you have just the mobo and psu connected.

Then switch it on, you should get at least a no CPU beep.
If you dont then I would say that the mobo is deaded ;)

Well, ive finally got round to taking this PC apart.

Ive taken everything out, except for PSU and mobo..........and there isnt any sounds or beeps etc, so is that 99% dead mobo?? Or could it be the PSU?

Its always worth checking the PSU as it could be a knackered rail but chances are if the fans are spinning but no-ones home...its the mobo.

Is there an easy way to check the PSU mate??

JUst it isnt my PC and tbh, I cant be bothered taking my main PC apart to try the PSU in the knackered PC, as Im not getting paid or anything.

if youve got a multimeter you can close the power switch pin and then read the voltages, other than that I am not sure.

Basically you short two of the pins on the atx connector. If the psu fan starts, then its not completely dead (and you can use a multimeter to check each of the voltage rails one by one).

more than likely.. make sure there is a speaker plugged into the motherboard if there isnt one onboard

Try with CPU and then add the memory. I have had a board that does nothing  at all without a good CPU in, the fans still worked though.

PSU Tester.  

Although you will rarely use it its a handy bit of kit to have lying around.

Or hit it a few times with a sledge hammer, that will prove its failed totally and she needs a new one.

/totally useless post

Ive tested the PSU on it now, with it plugged in to the motherboard, but with nothing connect......the results are different to what they should be...

Pin 1 = 16.72v
Pin 2 = 9.9v        
Pin 3 = com        
Pin 4 = 4.72v      
Pin 5 = com        
Pin 6 = 4.72v      
Pin 7 = com        
Pin 8 =                
Pin 9 = 8.1v        
Pin 10 = 8.1v      
Pin 11 = 3.3v
Pin 12 = 9.75
Pin 13 = com
Pin 14 =
Pin 15 = com
Pin 16 = com
Pin 17 = com
Pin 18 = 4.72v
Pin 19 = -6.47v
Pin 20 = 8.09v


So they arent really what they are suppose to be, so is it knackered do you think??

Worth trying a new one, TBH you have went beyond reasonable.

If she isnt running anything particularly meaty then it should be cheap enough. The question is what other damage it did while dying.

Told her to get a new one, as well as a motherboard.
