Hi all, I am trying to fix a PC for a woman I know, I had recently re-installed Windows XP for her and she was very happy, it was like a new machine.

Then, after 2 days of it running like a dream it, in her own words, started making a very loud noise, like a drill, and she had to turn it off at the wall to stop it. After that it wouldn't turn back on.

Actually it does turn on, the lights come on & the fans start, but there are no beeps. I have reset the BIOS but it made no difference.

I have bought a PC Analyzer, plugged it into the PCI slot and rebooted the machine, again, the front lights come on (just a power light really), the fan spins up, but nothing even lights up on the PC Analyzer Card.

Normally I would say the MB is shot and the PC is not worth repairing, but I feel that I should do all I can to get this working, even though it's taking up way too much of my time !!!

Now obviously that kind of noise would suggest a fan or Hard Drive problem, but surely if that was the case then it would at least try to boot up & I would get some feedback from the PC Analyzer Card ?!?

Any ideas out there ?!?

Thanks in advance ...

Hi and welcome to FpcH

You say no POST beeps .........
Please take a look here - click here

Strip the motherboard of major hardware / connections to just the main connection from the PSU.

Switch on.

Does the machine still make the loud noise?
This sounds very much like a fan hitting a wire ............ have you checked for this ?

At this point - ( m/board stripped down ) - you should get POST.
If not then it could be either the PSU or m/board itself.
( This does not explain the loud noises )
Check the PSU fan too - this could be the cause.

Let us know how you get on :)

KenB, thanks for replying, I'll take a look at that link, but before I do ... I, personally, haven't heard that noise. Since I have brought the PC home & I boot it up it's quiet as a mouse, the fan is spinning perfectly, the DVD ejects perfectly, but there is no other sign of life. The HDD sounds like it's starting up when I boot, there are a few very quiet whirrs & clicks, but no sign of life on the Analyzer Card or the Monitor (and I tried a new Video card to override the on-board card as I thought it may be that) ...

best thing to do is strip the m/down as per link.

There is a link at the bottom of the tutorial to "Testing a PSU"
This may be useful if you have a voltmeter.
