[now resolved - thanks for your 2p's worths ;) ]

Hi peeps,

I was asked to fix a PC by a friend who presumed that his graphics card was dead. I tested his card in my own computer and it was fine. Anyway, the computer in question is a Fujitsu scaleop with a 3ghz p4 (celeron LGA 775) processor - 630 SL7Z9 Phillipines. The motherboard seems to be a custom one for this system based on the Asus P5SD series - P5SD1-FM2/S

HDD, DVD-ROM, extra network card, gfx all tested ok on my system.

PSU seems to be ok, in that it powers up the CPU fan, case fan, case lights, HDD starts up, DVD opens/closes etc.

After talking with him it seems that the computer was kept in a poorly ventilated corner under his desk where it doubled up as a footrest while it was on :) - and he had to replace his old CPU because it died (I presume from overheating).

The components were all covered in dust, and the CPU fan and heatsink fins were quite furry, so I've cleaned up the whole inside of the case, removed and replaced CMOS battery.

There is currently no POST beep and no error beeps, the components are clean.

Nothing changes when I try swapping around or using singly the RAM sticks.

Am I most likely thinking to replace the CPU? Or would you say motherboard is more likely?

Stopwatch starting ... now! :)

EDIT: Should have said, I don't have a socket 775 mobo or 775 processor to swap either of these out with for testing, so I'd have to go buy it and I'd rather not have to buy both.

Im thinking the motherboard, buttt

have you tried to get some output on screen by just connecting the motherboard, cpu, ram and graphics card to the psu and try to boot into the bios?
 
I've not managed to get anything up onto the screen at all since I received it from him.

Not at any point.

The motherboard would be a real ***** to replace, at least like-for-like. I'd hoped that since the mobo seemed to be powering all components it might be a case of simply replacing the CPU. I dont have a spare socket 775 CPU or a spare socket 775 mobo.

The hard disk, cd drive e.t.c would power up due to been directly connected to the devices. The motherboard seems to be gettin power, however no output. Have you tried resetting the bios at all?

Yes, I've used the the jumper reset method, and the taking the CMOS battery out for a minute method as well...

How about just getting a new mobo/cpu combo :p

i dont have infinite money personally, and neither does my mate. :)
 
Can you swop the PSU over with another one to confirm this does work, it may supply 12v to the other items but not the critical voltages to the board.
 
Try leaving the CMOS battery out for longer. Like a whole afternoon, has bought pc's back from the brink for me a few times. Take the battery out, unplug from the wall and mash the power button a few times to get any residual juice out and leave it alone for an afternoon.
 
power supply transplant resulted in no change, so as suspected, it probably isnt the power supply.

I guess I can leave the CMOS battery out til tomorrow evening. It couldnt hurt.

i pretty much have the same problem, and i have decided that it is the cpu. My replacement cpu should come on tuesday, so if you haven't got it sorted by then I will report back.

I hope it's the cpu because it means if bought an extra cpu for no reason :P
 
Hey quick question, is there any diagnistic software out there (my old PC has same probs). Is there any motherboard manufacturer diagnostics sw that you can install on another PC, hookup to your motherboard via ntwk/usb (or even internal connectors/jumpers), that will run a system check on the motherboard/CPU, and give some details of what seems to be responding/working or not?

Would have thought manufacturers would have this kind of stuff, just wondering if its possible to get hands on...?

Well, a lot of PC repair places have at least one of each type of motherboard (slot A, slot 775, socket 1, etc) for testing and diagnostics. Like we were saying the easiest way to test the processor would be to test it on a known to be working motherboard of the same type. There are so many different motherboard designs it would be near-on impossible to have a universal "tell me what's wrong with this random motherboard"-type connector. :)

One factor I hadnt considered in all this was that that I would be using up my precious arctic silver thermal compound :eek: *sigh*

Oh well... I'll get back to it this evening. Hopefully someone I know will find a spare processor so I can test whether or not it's the motherboard by then. ... I may need to nip to the local rip-off merchants to buy some thermal compound beforehand of course (£5 for a tiny tube of no-name compound, about quarter the size of yer standard arctic silver syringe thingy!) :)

I would suggest testing the old processor on another board first even if you have to go out of your way to do so!.

A dead cpu would probably confuse but not fry a good test board but the other way round

testing a good cpu on a bad board invoves a lot more and higher voltages/currrents & higher risk
 
Update:

Tried everything to revive the mobo, then saw a very cheap exact same motherboard on an auction site with 30 day warranty. Took the chance on it, and finally got around to trying it today. Worked first time. Everything is now funkadelic. Or at least good. :)

Thanks to those who posted advice. It's good to know that people are always willing to help on these forums :)
