Dead PC ?

Hi, Was wondering if someone more experienced than myself could help me.

Basically I have an old PC which wont boot, it doesnt even POST I believe as there are no beeps at all.

When I turn it on, it does power up for about 5 seconds before turning itself off again. In this time, none of the case fans start up but the cpu fan does.

As there is some life, I am assuming its not a power supply fault ?

I have now stripped out most of the components, Sound Card / GFX Card / HDD / Memory, and after each removal tested again with no luck.

To me it seems to be either down to the motherboard or CPU, but is there any way to tell which. Or does this information suggest something else is wrong?

Thanks

Yea I tried with one stick, and with none (And got the same results), I didnt try the 2nd stick on its own though, which I will soon. You dont think its PSU then?

Would resetting the cmos battery help at all?

Erm. The PC is about 5 years old now. But hasnt been used for the past year or so due to not working. Think it has an AMD X2 5000 CPU, couldnt tell you exact MB but socket AM2 obv. 500W Nexus Power Supply, 9800GTX card i think... I have now removed the cmos battery, how long does it take to reset ? And i will try to restore the bios if this doesnt work.

Pretty sure i managed to reset the cmos, and still nothing. That means its the MB most likely then ?

Ok thanks, I will attempt to test with another psu in the morning. I dont think its the ram as i have tried both sticks on their own, in different ram slots and still the same, its also the same with no ram installed at all. And the cpu has never been overclocked. Was used a lot for about 3 years with no issues and then not used much since. So most likely will be the MB i guess ?
