Need Help Diagnosing A Hardware Fault On My PC

It looks to me that you have done a very thorough job of fault diagnosis and i agree with your conclusion that the fault could well be with the CPU.

 

Hi Rik, thanks!

I have a fair share of knowledge when it comes to pc hardware as i usually build and upgrade pc's on a monthly basis. Im just not convinced its the processor though. Shouldnt the bios boot up without a processor in the slot or would it not ?

 

Have you tried another PSU?

I know it's not old, but stranger things have happened.

Seeing as theres no "BEEP", and it's not the Board or RAM...

 

Hi fragrant coit,

its crossed my mind but then i thought that the motherboard barely needs any power to boot up, and it seemed to power the hard disk fine when it was plugged in so should atleast power the motherboard without a hard disk.

I will still try it though and post the results! Thanks for the advice.

 

I wont argue with your knowledge mate. If only more people would take the time to make a quality post that explains what they have already tried as you have done.

I too have built, upgraded, refurbished, and repaired many a pc.

To your last question, if the CPU is a non runner then the bios usually doenst work either. Altho, I am a little concerned about what you said about the dvd drive tho. Just in case, do you happen to have a different known working psu to test with?

 

Hi Rik, sounds like were both men of the world

Im also very confused about the dvd drive issue. Its as though it is linked some how but the bios would power up even without the dvd drive plugged into the motherboard.

Im currently taking my hiper 580w psu out of my gaming pc to try it. Hopefully this should narrow it down. I will post the results as soon as its done.

Thanks for the tip.

 

Remember the PSU outputs a few voltages, your fans may spin like there's nothing wrong, but the CPU or RAM could be getting no juice.

 

Hi,

I have tested it with another power supply only connecting the motherboard up and using onboard graphics and it has worked straight away!

I forgot about the different rail voltages though, but i cant see how the motherboard connectors wouldnt power the motherboard up fully when they have done for almost a month now :S Perhaps its down to a faulty power supply.

Thanks for your help by the way fragrant coit and rik. Your both superb!

 

If that psu is still under warranty then get it replaced. I would check out that dvd drive next if i were you.

Do you know how to test the suspect psu? If not, i can help.

 

Superb! I'm used to shorter names {like 4 letters!}

Glad it's sorted.

You could always return the PSU, but some don't have much of a warranty due to Voltage spikes, blackouts etc.

Rik beat me to it - I'm an awful typist!

 

Hi Rik,

yeah its under warranty so it should be easy to get it replaced.

I dont know how to test the power supply though so would appreciate it if you could give me some tips on it. I dont have access to any sort of amp meters or anything though, or are they not needed?

Thanks

I think rik is non looking at keyboard typer The company i purchased it off have amazing customer service so i wont have any problems getting it replaced.

I wish, I'm just very proficient with using spellchecker very quickly lol.


In order to do some basic tests on the psu you will need a digital volt meter and a bit of wire.

 

I thought i might have needed some sort of volt meter, amp meter or any another sort of meter.

I think im just going to send it back to ebuyer.com and request a replacement.

Thanks for all your help though guys, i really appreciate it. I Think im gonna head off and play on my other pc for a bit, shoot some kids on battlefield 2142 to unwind after a long night of computer stress

Goodnight!

 

Hope it all goes well.

Come back and let us know what happened.
