Computer shuts off after 3 seconds nothing displayed on the screen

[anthony25yo]

The other day I was trying out my computer after not using it for a couple of weeks...

It's an Athalon 1.6mhz and the MB is: ECS K7S5A sis 735

It turns off after 3 seconds... occasionally it might make it to windows before it shuts off. I have to inplug it from the wall and then try again...

Does any one know what the problem may be? I've heard it could be the MB but I don't want to have to buy one and then have the same problem..



I've tried a different PSU and it still the same...


The fan comes on and I don't hear any beeps..

I removed the ram and it still did it.. I also took out the video card...

Can anyone help me out please!!!

it could be a bad video card, what kind of card is it?

 

[anthony25yo]

Thanks for replying.. I'm not sure what card.. but...

If I try unplugging the card would the comp still run?

If it ran without the vid card we could then say that this is the prob...

I think I tried it before and it did the same thing...

 

[Tommy Boy]

no, it can't run without the vid card. do you have any other vid cards that you could switch with it?

 

[anthony25yo]

hmm I can try another video card with it though..

I'll give it a go

Thanks!

if that doesn't work, you might have a bad motherboard...ECS isn't exactly a great motherboard

ok you can check out This site , to see if it solves some issues.

But would the vid card be faulty if sometimes I can get into windows and the screen appears to be fine i.e. no blinking or anything..

There's no beeps at all...
Should I just invest in a motherboard??

Are there any telltale signs that it's the CPU or MB??

could be the motherboard, that is a sign of a bad motherboard. I had a friend that had a computer that restarted randomly, turned out to be the motherboard
