Weird power pulsing problem


OSNN Senior Addict
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

Just tried it on your suggestion, no difference, thanks anyway. This means that I have disconnected / unplugged every single plug on the mobo now. I'm think the mobo must have bit the dust?
disconnect all your devices too. I'd suggest sliding optical drives forward to ensure no contact.

All you should have to power on is a bare motherboard (no cards, no ram, no devices plugged in. Then use a flathead screwdriver to turn the power on. If it still pulses take the board out the case and try it again.

If it still pulses you want a new board.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
