Do I need a PSU replaced?

Hello, there.

I am wondering if you can help.

It looks like I need a new FSP PSU.

I have a Packard Bell Ixtreme Gold MC 1807 desktop and recently
after being switched to hibernate it refused to do so. Well, it seems to have
shut XP and froze. I could not do anything even turn it off by pressing
and holding the power button. So I had to pull the plug.
Now after I press power the button (after the reconnection to
the power) it would not start, however, the CPU fan and the fan on the
motherboard (on the processor) spin normally, yet the HDD does not
spin.
If I want to switch the pc off (as nothing is happening, BIOS is not
loading, no beeps or anything), I have to physically pull the plug out
of the power socket as the pc does not react to my pressing the power
button at all.
The light on the motherboard is on and the light on the power
button is also (but red light, not blue).
THe monitor shows a message "check signal cable", but I think
this is because there is no signal coming to it as the cable is properly
attached. A have checked all the connectors and they are fine and there
is no sign of burn marks or smell.
My guess it is the PSU problem, perhaps, it's either broken or
become insufficiently powerful for my use (it's only 250W, the model is FSB
250-60PNA-E(PF)). In that case I need a more powerful PSU.
Can anyone please confirm/dismiss my

Appreciating your help and waiting to hear.

Best Regards

The PSU, is indeed, one possability, however, there are many other possabilities also, including but not limited to, the graphic card, the hard disk, a stick of RAM, or the motherboard it's self!

The lack of POST beeps or other signs, makes it more difficult to know where to begin looking... I honestly can't suggest the best place to start, it could be anything, it's just a matter of picking one, and checking it.

If you have multiple sticks of ram, try removing all but one stick, if it still fails, swap that stick for another one, you could also disconnect all non-essential hardware from the motherboard to see if that will let it boot (ie, disconnect any CD/DVD drives you have from the motherboard and from the powersupply, remove all USB devices, etc)

If it's not the RAM, or a secondary device connected to the motherboard, then it has to be one of the other things in the list above, but finding out which one without spare hardware to try (or another computer to try the bits in), then you could be looking for a long time before you find it I'm afraid.

Thanks a lot. I will do as recommended.
I have also borrowed a PSU tester and checked the PSU. One of the indicators on the tester was not lit, but there is inconsistent info on the net if this is a problem for this PSU or not...

If the hard drive isn't spinning up, then certainly the PSU (or hard drive) is dead. It doesn't have to be connected to the motherboard to spin up.
