URGENT: Power cutting for no reason

post #1 of 9
Thread Starter 
Hey guys... sorry if this is in the wrong section...

I was watching some House, and out of nowhere, the power to my PC cut. No power blink, nothing. I tried to turn it back on, but after 1 second, it cut again. I removed the PSU power cable, put it back in, flipped the PSU switch off and on, and turned it back on and it seems to be working now.

What happened? Should I be concerned...?

Check for any temperature rise in your system, any fans going dead especially in the powersupply if all temps in the rest of the system seem ok, and if all of that pass the checks it could be a loose wire somewhere.

In the case that something overheated, your system would shutdown automatically and refuse to turn on until temps dropped a bit.

I had that very same PSU, it murdered my AMD rig. I had the exact same symptoms, random shutdowns, until one day it wouldn't post. No beep code, the motherboard would spin the fans and light the LEDs, but the monitor stayed black and the monitor's power LED stayed orange. Replaced the motherboard and everything worked fine for about 3 months, then it happened again, a random shutdown. Restarted to find that the system didn't work at all. Tried the memory in another rig, both sticks dead. Tried the motherboard/CPU in my new rig, dead. The PSU finally bit the dust and killed my RAM, CPU and motherboard. Those PSU's are known killers, the Antec Truepower series seem to be failing around the 1.5-2.0 year mark. I can't promise you this is the cause of your shutdowns, but your symptoms do suggest a bad PSU and this is a known issue with that model. I'd replace it with a quality Corsair PSU before it takes your system with it. Try this guy, great deal on a great PSU!

I agree with Durch, the first thing I would turn to when my computer is randomly shutting off is the power supply.

Alright, thanks so much guys... I will probably replace the PSU.
And this summer my PSU will be three years old... so yeah, I should probably replace it soon. Haha

Try jump starting the PSU. On the 24/20 pin, connect the green wire to black wire.

See if PSU starts. If you have a multimeter, check the voltages.
Once again...
