Weird power pulsing problem

[belveder 0]

This morning my second computer started playing up, it seemd to have no power, even the fans could only run at very slow speeds.

 

I thought the PSU was faulty so I put a spare Thermaltake 750 watt PSU in. Now when I turn the power, the lights and fans seem to pulse and nothing else happens.

 

I have tried it without any cards or accessories with no luck also checked the memory

 

Any help would be greatly appreciated

Take a look at the motherboard and see if any of the capacitors are blown. They will look either popped up a bit or be oozing if they are indeed blown. If this is the case, your motherboard is fried.

I can't see any blown, also I have disconnected every plug / cord / card from the mobo now and no difference. This includes the cords that go to the reset button and all those.

 

I'm guessing the motherboard has died?

That's mostl likely it. In the unlikely event that you have two faulty power supplies, test one of them out on a spare machine.

Thanks for the replies. The other half has decided to get a more up to date pc.

Well, that's one way of doing it, although you miss out on all the fun of dealing with hardware.
