Hi guys!

There is an unusual clicking sound which occasions itself around my PC. At first I thought that my Hard Drives were going, but it then led me to think that the CPU fan was going. But on opening up the PC, I noticed that a lot of dust had accumulated, so I cleaned it out and noticed that the fan in the power unit wasn't going round when swithced on.

It makes a horrid noise like it's trying to revive itself - but is it time to get a replacement unit?

Thanks

Good Morning moozer, absolutely, vitaly important!
Hasten before something is destroyed.
The PSU is a complicated Switching System that is engineered with the cooling provided by the fan, sometimes these fans may be replaced but it is possibly safer to consider another PSU.

Thanks!
Will I need to get the same power rating. I think I have an old 200W PSU but this one is a 300W. I would assume that I need to keep to same rating but not sure about electronics!!!!

If you currently have a 300W it would be better to be equal or greater than.
If you have only limited power useage with a basic machine and no fancy gaming type video card or high power needs the 200W should be satisfactory.
What is the system, processor, video and drives? And what application?

A simple system:

Intel Celeron 366Mhz
320 MB RAM (2x128MB 1x64MB PC100 SDRAM)
8MB on-board AGP graphics
1 on-board Sound Blaster
2 HD (1 = 4.2GB 1 = 2.1GB)
3.5" Floppy drive
CDROM (12x)
USB game pad
USB webcam

Using Windows 98 Second Edition
As you can see it's a basic system.

Good Morning moozer, with that particular system the 200watt should be satisfactory, but run Everest and check the sensors page voltages when you fit it.

If you experience any problems with "hanging starts" move up.
Pay attention to any USB devices you might plug in and their power consumption.

Well, the maximum amount of power a USB device can draw is 2.5 watts ([email protected]) for a single connection, so they're not exactly "power hogs". :D

Yes but 127 of them is a bit much! LOL!

Good Morning Rumpo, You are very astute, valid point!
How come John missed that! LOL!

The easiest way to tell is probably the power lead going to the remote "on" switch.
I think moozer would be aware of that though.

Just replace the fan and be done with it. I've replace the fans in power supplies multiple times. Use a ball bearing fan of the same size.

Try to keep your hand away from any large capacitors.

And take the time to blow the dust out while you got it open.

Thanks for the links everyone!

Doesn' t seem to be any noises/clicks from PC at the moment - I'm sure that's just a temporary thing!!!

I'll open up he PC once the noises start again and determine if it's the drives or the PSU - the Hitachi website could indicate a drive head failure (sound #1 sounds similar to mine)

Will get back to you soon!

Thanks in the meantime!

Andy

If you're hearing a sound like that, my initial guess that it's the disk seems to be the most likely. You really do want to BACKUP right now if there's anything you would not like to lose on that disk.

I'm not entirely sure what I should be responding to. :confused:
Good Morning JohnWill, the point was, that considering the RAM in that machine, it was likely to have an ATX PSU, the probability of the 200 Watt PSU mentioned may well be the older AT.

Ack!

The damned thing failed before I could do anything!! It was the larger of the two drives and when considering that I had over 9 hours of music on it (downloaded using 56K dial-up) - it's a little frustrating!!!

Thanks to all for their help
