Started college last week and we were given computers to do all our work on (ICT practitioners).

Today we tested them, took apart and re-assembled.
Obviously, Im 1337, so mine worked

, but a friends wouldnt have any of it.

Firstly it would power straight on when the power lead was inserted....corrected after reseating everything.
Now it wont show a display and the power LED is constantly on. It wont beep at all, so Im assuming its not POSTing.

We reseated everything apart from the CPU, because the heatsink was a right pain to get on/ off.
Disconnected everything apart from the hard drive and still nothing.
Power LED is still bugging me

Tomorrow we're going to take a working unit and swap everything over bit by bit until we find something broken.

Anyone have any ideas? If this doesnt work, he's going to have to pay for another unit (we get one working unit free, if it breaks, we pay for the next.

Spec of the system would help.

Rik1254 · 28 Sep 2011 at 18:33

**** knows...some old Pentium 4, teeny tiny HDD...some crappy intel mobo.
Its an old college jobbie, so nothing spectacular.
But how would knowing the spec help in finding the problem?

Power LED on while system is off?

Never seen that before, I recommend an exorcism for that machine.

Rik1254 · 28 Sep 2011 at 18:39

Yup, its getting a constant feed from somewhere, but when the computer is powered on, it goes off.
should have also added, its holding a lot of charge, the power LED is staying on for a good 2-3 minutes after the power lead is removed.

Try a different power supply?
EDIT: I am doing a similar course to you but the Level 3 Diploma

. Haven't even got to taking them apart yet most in my class just about know how to turn one on!

Rik1254 · 28 Sep 2011 at 19:13

Yeah im Level 3 Extended Diploma.

We're going to try everything tomorrow. We've had 1 power supply burn on us and almost catch fire...not sure how that happened, another computer popped all its circuits, nice little light show we had going on there

.

Right now, the only things we havent changed are the CPU, mobo and PSU. We cant change the mobo, so everything will have to be transferred into a different machine.

Buchanan0204 · 28 Sep 2011 at 19:16

Guaranteed it's the PSU... especially if it's old and crap (which it will be)

CPU's rarely blow... like never.

That's why I wanted to know the spec... to see what make and model the PSU was. Also if someone else has a known fault and it may well have been documented.

Rik1254 · 28 Sep 2011 at 19:28

Its only a year and a half old tops, these were new systems for last septmember, but with the other PSU's, they failed pretty much instantly once we took them apart.
