Hi newbnew,

Have you tried to go into Safe Mode and see what happens?

It's also possible that you might have a bad motherboard, if you tried a new power supply and different memory.

Dude...
1. You may have a corrupted MBR. This can be fixed many ways. The simplest way would be to boot from your Windows cd and do a Repair install (go through the prompts as if installing new and when it checks for previous Windows install it'll give you the repair option).
2. Your CPU may be overheating (dirty, bad fan, etc.). Check this first.
Good luck.

I put a tube of high performance cool master on and still the same problem. No audible sound just a power down and about a 3 second wait before it restarts on its own only to repeat the same behavior.

does it shutdown if you leave it in the bios?
then it is a hardware temperature problem.
btw >>  I put a tube of high performance cool master    <<  you need only a drop or or 2

and check your mobo for leaking or bulging capacitors, as per www.badcaps.net

Make sure the CPU fan is connected to the FAN headers on the motherboard or it may shutdown to protect the CPU.

I did the above suggestions, I suspect that the mobo is not the original although I could be wrong but there are marks in various parts of the mobo that were done with a sharpie or other. No bulging capacitors.

I got it to run long enough to attempt a system recovery by pressing F-10

It shut down during the attempt. I have a feeling that that may have been my last hope.

The system isnt posting, you need to check all the jumpers and header connections. make sure the cpu fan is connected to the cpu fan header.

You have to take it back to basics. Pull out any unnecessary cards as well.

Nobus, I apologize for my short answer, I was in fact answering your previous question while complying with the following request, "can you answer my questions?   without info and feedback - impossible to help"

I thought you wanted a yes or no answer which is how I interpreted your reply. By no means did I intend to offend you or anyone else nor was I trying to be rude.

I tend to ramble and I took it that I did in this case, now I see that I should have explained more clearly.

I was replying that No, I can't get the computer to reboot from software, safe mode or any other function.

Sorry my friend

tx for the feedback, newbnew
i'm not offended - (you get used to it here); i'll list my questions again :
does it shutdown if you leave it in the bios?
can you boot from a cd? and does it stay up then ?

newbnewAuthor Commented:
No to all of the above, my customer said not to worry he wants me to trash it. I suspect either the CPU or the MOBO is bad, is there a way to pinpoint either of the two without first buying a replacement?
0
 
nobusCommented:
difficult, you can try if it beeps withaout ram, see if it shuts down if you hold the power button, etc.. but not conclusive.
failure rate is95 % mobo, 5% cpu

joolsCommented:
could be the psu is not up to powering the system.

do you have the additional power connected to the graphic card? I am guessing about your hardware here.

newbnewAuthor Commented:
It is built in to the mobo,  the customer has written it off so now I am just learning how to get it up to operation, I suppose I will search e-bay for a used mobo and go from there, it's a learning experience,

Thanks again for all the help.

How can I distribute points to multiple experts? Everyone was helpful with providing a point to zero in on and I appreciate all.

joolsCommented:
I believe there is an `accept multiple answers` and you distribute as you see fit.

What kind of power supply Is in there?  Other than overheating, it seems like an underpowered machine.  I have seen a few of those.  Especially if someone tries to upgrade the video card or add a hard drive.
