PSU or MoBo?

[Aizuchan]

Hello All,

I'm having a problem with my PC and I can't figure out if its the motherboard or the power supply.

The problem: Last night the computer went into standby, and it went to power itself off and I hear two clicking sounds and then it "turned off" but the power button was still on. It had done this before but I simply restarted the PC and everything was fine.

The symptoms:

The monitor says no display - This happened in the beginning. For some odd reason the VGA will only display from the gfx card. Even if I remove the gfx card the VGA port on the MoBo wont display. (all of the gfx drivers were updated)

Some components have no power - The fans, front LED, reset button seem to have no power. I can't tell if it any other components have no power. However, the computer turns on and the fans on the CPU fan and gfx card are spinning.

What I do know: The hard drives are both functional. I attached them to a secondary PC and they are recognized by the other tower. The Ethernet port is also receiving power.

The gfx card is a temporary card. I got 750 for the PSU because I plan to upgrade the gfx card later. The monitor is an old flat panel (Viewsonic VG700b)

Any advice is greatly appreciated!

I think the PSU is dead the 2 clicks are most probably short circuit sound from the PSU.

Thank you so much for replying. Is there a reason why the other components have power?

That would be most unfortunate. I've only had the PSU for maybe 2 months?

okk if the other components have power then do one thing it may help.

open the plug of the psu from the power socket remove all the cables of the psu to the board and other components like HDD dvdrom etc remove the ram the BIOS battery press the power button for about 20 sec to drian the excess power then put every thing back together sometimes this helps . So try it.

Sorry about the delay. I don't know how you discovered this, but this solved the issue. Thank you so very much!!! I was able to finally boot the PC> Do you know why this happens? They are going to RMA my PSU, should I still go ahead and get rid of this PSU? IS the clicking sound a warning it is going to die?

it may be a short of someking in the motherboard due to short curcit in PSU so yes you better RMA the PSU.
