flashing/blinking LED?
The computer is off but the PSU is turning and the LED light in front (HDD led?) constantly flash.
To stop the PSU fan turning, I had to disconnect the mains cable.
Suspecting PSU being faulty, I tried a different PSU from a working PC but same result.
What could it be? the Motherboard or....?
I looked on the web without success.

either hibernation, the machine was put into sleep, or you're having a problem with your motherboard.
I'm hoping it's the first two.

im pretty sure its your motherboard. do you still have the manual? they sometimes have code signals (makes the lights blink in various patterns) for the LEDs that represent various specific problems that can help deduce. theres also a nifty, fairly inexpensive device that you can get from tech stores that plugs into the motherboard and returns a number that can be looked up for a diagnostic result.
and you should ask Genesis. he's good with this kind of thing.

Yup blinking leds normally a dead/problematic motherboard.

thanks for your replies.
I too think it is the motherboard but needed some confirmation -- the machine is an emachine (my friend's, not mine!).
Should I just get a new motherboard or a new computer (minus monitor)? The specification is as follows:
- emachines 620
- Intel Celeron 2.7GHz
- 80Gb HDD
- CD-RW 48x max write
- DVD 16x max read
- 512Mb DDR (PC2100)
- 3D AGP Geforce FX 5200 64Mb with TV out
- 56Kps modem
- 6 USB ports
cheers

you might be able to find the motherboard for that processor for a good price. but, its possible that the motherboard was some kind of "special" version that you cant get retail. so, the retail equivalent may not be compatible with some of the rest of the hardware which could be "special" as well. i would be particularly concerned about the "specialness" factor on a budget e-machine. in order to offer low prices for machines, computer manufacturers sometimes contract tailored parts in bulk from third parties that lack some of the universal plug-in ability that the shelf versions have. so, many of the parts may be semi-proprietary and dependent on each other. ive experienced this with some motherboards from packaged pc's and some other hardware. even a set of speakers and soundcard from gateway would not work on anything but the original machine.
anyway, not sure if that helps to make the decision so much. if it were me, even though the mb replacement may be a lot less, i think it would be better spent toward the cost of a new machine.
[i would buy a newer, better set of mb, cpu, ram and case and plug in as many devices from the old machine as possible.]

I don't know about the motherboard being bad. If it's able to blink and give some sort of POST diagnostics, something like the RAM or processor may have gone bad. Try taking everything out and replacing it very carefully (making sure to seat everything properly). I had an older maching that had an ISA video card. The ISA slot was offset a little and when I tried to put the card in, it wouldn't seat firmly and the machine wouldn't turn on correctly. AGP is particularily finicky since it has two rows of contacts.

cheers for the replies....
I took both RAM and AGP card out and put them back in -- no difference unfortunately. As far as I can see, there were no POST messages but the keyboard and mouse sometimes do not work (both use PS/2).
Could PS/2 port an issue but how can it be tho? The PSU fan was still turning even after you did a shut-down.
Would it be enough to purchase:
- new CPU processor (either AMD or Intel whichever is cheapest)
- new motherboard (that accepts DDR RAM)
And just use the existing components/periphals and the case -- would that work?
Btw, the RAM is a Samsung 512Mb PC2100 2.5 so it should work ok on non-emachine computers.

Are all of the system fans turning? On some machines if the main processor fan isn't functioning properly, the system won't run to protect itself from overheating.

when the computer is turned off, the CPU fan stopped turning but the PSU fan kept turning.

That's odd. I'd replace the motherboard, then. There's no telling with ATX power supplies. With all of the new power management features available with ATX it really throws in a ton of factors when trying to diagnose something. That's why I'm a firm proponent of those PCI / ISA POST card readers. They really come in handy for something like this.

never heard of this POST reader thing -- ebuyer does not have them but found a few on ebay like this and this
Dodgy or worth getting?

Yes - You probably need another HD though, unless you have the stuff from the current one backed up somewhere. Windows is tied to the mobo - change the mobo on a windows install, and Windows will not boot - so you'll need a fresh install(not a bad idea anyway).

Yeah gfx card, ram, etc. Should be fine. Might even be worth getting another cheap 512 stick in there - pc2100 - 512 - 2.5 CAS - $38.99 USD

cheers mate for your reply -- I will look around for a suitable motherboard and CPU. Maybe also get a new PSU -- apparently, emachines' PSU is of poor quality and the output is too low for the motherboard to handle (or something like that).
