Pc (desktop won't boot)

by one228 Oct 21, 2016 10:15AM PDT

Hello, I am having some problems with my desktop pc.
Basically the pc will not boot up, When I mean this the pc will turn on the desktop unit lights up but nothing will show on my pc screen.
The things I have tried are,
Taking out everything from the pc unit so its just the motherboard and the power supply.
Resetting the CMOS.

I am just wondering if anyone else has tips that I can try or is it just my motherboard is screwed and I need to replace it ?

The machine itself I built and is only about 1-2 years old.

Thank you

So motherboard and PSU?

by r. proffitt Forum moderator Oct 21, 2016 10:42AM PDT

Nothing else? No case too. That means the remaining parts are suspect. What part is suspect?

Don't know? Replace the cheapest part first.

I can only assume the motherboard is the problem as all the fans are working.

Its like cycling on and off when I turn it on.

Share full make, model details.

Once in a while you find the famous 4 rail PSU, next time you find the 250W PSU.

Let's hear more.

Also, as you are a PC repair tech, did the PSU pass the old Green Wire Test?

Problem(s)?

If its already 1-2 yrs. old then I assume you have a prior problem and trying to fix it. If that's the case then you come across a low-level failure or a major componeent that's hosing the PC. Being such a basic PC, then you have to look at the setup. Be sure its all correct, heck just the mtrbd. and PSU and the speaker in order to hear any beeps. If beeps arise, then locate the bios beep error code to help along this issue. Otherwise, not resolving anything then pretty much states the mtrbd. is kaput. If the PSU passes the short wire test, then maybe OK. Just swap out the PSU for now and test again. If it still fails, then the mtrbd. should be replaced. If you re-use the older componenets again, verify they're OK because you may retrduce the problem again, even if new sooner or later. Sorry, but that's the way it goes with no fancy testing equipement to help along the way. I also suggest you review the proper cabling hook-up sometimes having improper hook-up cause issues as well, it become a simple wild card until found.
