Pulsing Power
« on: November 18, 2013, 02:05:10 pm »
I've been using my new desktop for a month or two now and the other day I put it into suspend while I slept. When I got up it was powering on for about half a second every five seconds or so. I rechecked all the wiring and it appears to be good(or at least unchanged) but the problem has persisted and I am unable to turn on the computer. I've tried clearing CMOS to see if I messed up with my overclock(4770k at 4.0ghz), but that didn't seem to change anything. At this point I'm not sure what to do. Any ideas on what is wrong or how to fix it? I have decent warranties on most of the parts so I should be able to get a failed part replaced(would that be PSU or motherboard in this case?)

EDIT: The customer support at MSI suggested I remove my graphics card to see if it would work with onboard video and that(predictably) did nothing.

EDIT2:It worked for a minute while the graphics card was out and nothing was plugged in except the front panel power switch.
As I started plugging other things back in continued to not have problems until I plugged in the power led positive. Then the problem restarted and is not going away. It stopped earlier when I was unplugging things and had moved one cable slightly to the side(not unplugged just moved it away from the processor fan)
I tried redoing everything I did, but the problem is not going away again.

I've had that problem before but it was a while ago. I can't remember exactly what I did but I can still hear the whirring of the computer when it started then the almost instantaneous sound of it dying down. Try removing removing all but one RAM card, try turning it on, if nothing, try the rest of the cards one at a time.

I eneded up getting this working by pushing every cable in the case in to make sure there were no loose connections. I now have a few problems with monitor cables so I need to keep working on that, but it is kind of good for now.

You should check if the ground prong of your power socket is actually grounded. Especially if you connect your Computer to any other mains-powered devices - such as a monitor or a network switch.
