Thnaks for the info. A colleague already advised these are only necessary if overclocking.
Checked each of the caps AM. No leaks, no bulging ones. Definitely no dodgy ones there based on sight.
Checked, guided by the pics on post #7 of this page:

Close ups of all the caps? Sorry, not today.
No probs.. Just me being anal... The tec in me just wants to confirm.. It is part of teh learning and understand process.. The board jockey approach is just hard to deal with... But I also understand that some time; that is the way it is.

OK, update on this. bassway was right. The CMOS I think: After removing RAM and cards and cleaning contatcts, the BIOS displayed some funny characters then, on reboot, no POST. Dead MB
Replaced (in order):
Power supply - unncecessary
CPU fan - a worthwhile replacement
1 GB hard drive - not necessary, but a useful purchase
motherboard + 2 sticks of DDM3 RAM
I now have a fully functioning system which should be good for at least two more years. Out of pocket the best part of $400
With the new CPU fan and a bit of silver grease the CPU runs at a cool 33 degrees - room perhaps for overclocking it a notch but I probably wont bother.
The old GeForce 8500GT graphics card still works fine - a noisy fan at startup but I might try IBs trick of removing, cleaning and giving the bearing a bit of a spray.
Are case fans and RAM heat spreaders worthwhile?
Ya want braging right = Yes
Functionality = Only if ya over clocking a pushing read and refresh rates or CPU ..i.e. Over clocking
Fans add noise and unless done correctly are of only little help to temps unless over clocking... If the Ambient temp is up... Only one way - Aircon.
Can ya take a pic of the dead MOB... Close ups of the caps...

Thanks melbuurn
I didnt think of the memcheck - realsied Ive used it before but my memory fails me [smiley=huh.gif]
Ive stuck a new CPU fan on it and it didnt lock up at start up. Thats promising! Installed the Probe utility and the CPU temp is running at 40 degrees.

if you want to test hardware, download yourself a copy of memcheck, free open source memory tester - will tell you if you have bad memory (jokes aside).
Have you recently changed the orientation of the way your computer sits? I have seen instances where servers are sitting on shelves in a rack and then swapped over to a rack mount kit, the bearings in the HDD give way and the drives goes out to lunch.
If your in Melb, I can recommend a good computer tech to take a look (me)

I use my own method... Note: Less is more when it comes to the transfer compound.
The super nerdy techs at where I work tell me that the transfer compound is actually an insulator. Transfer is a bad term.
The insulation properties are far less then air though. So as the link that AM provided shows the compound is to ensure a smaller to non existent air gap between the device and the heatsink therefore better heat transfer.... I think I just contradicted myself.... ;D
Well "Transfer compound" is a bad term if you dont know what is going on.
ROFLMAO.. bassway.. Ya right.. Many just plunk it on.. It has better conductivity than air... Thus the Silver is good, but of course the less ya need the better.

So do any caps have popped or bulging tops.. ???????
Im not at home at present so I dont know.
Ill check out lapping later. After checking the CPU fan on the weekend, whomever added it the first time did a lousy job and I wont be getting him to build a computer anymore.

As I said... CAPS are popping..
Just confirming what you said AM, not ignoring. I already cleaned all the fans - CPU and graphics card while I had the box open.
I like your thinking BF. Ill take a gamble on the CPU fan first.

If so; fans etc are not worth the effort.

Remove hard drive and other peripherals you know are working take the motherboard outside with the addition of a little petroleum and a small flame stand back
But do not breath in all the cancer causing chemicals...
Remove hard drive and other peripherals you know are working take the motherboard outside with the addition of a little petroleum and a small flame stand back and smile at the reversal of pain and suffering You are causing to your former PC. Then make a short and low stress trip to your local PC supplier.
Last motherboard problem I had (tried a new power supply and a clean first) I did pretty much as above, $350 for a brand new box for the office minus a few bits and got to keep my sanity. That included re installing the bits and setting it up. Still have the old case and I am going to put my old P3/win98 in it.

Cheers
Had a chat to a colleague and he told me to look for bulging caps.
60 is the threshold on the CPU temp monitor He agreed that the CPU temp is probably too high so Ill grab a new fan and some silicon paste and try that first.
As I said... CAPS are popping..
This will also cause heat issues... Due to the lack of regulation on the power supply to the MOB components and CPU.
1: Check to make sure ya FAN and cooling fins are clean... Bet they are all very dirty with fluff and skin deposits. Dirty fins will had 10C no problem at all...
2: Si past and a new fan will do little.. Need to lap the CPU and Heat sink and use as little heatsink compound as possible.. (Silver past is best) This will drop another 10C
If any caps are popping / bulging.. Then every thing else is a waste of time.
