PSU Died? Random Power-Offs

post #1 of 9
Thread Starter 
Recently, my computer has been randomly powering itself off, and then refusing to start back up. To start it back up, I have to switch off the PSU and unplug it for a minute or two. Then I can re-plug it in, flip the PSU on, and then power up the computer again.

You guys think the PSU is dying?

I think it may be. First, check all the connections inside (probably did it already). Just get another PSU, the 450 watt ones by Corsair are excellent and pretty cheap.

What happens if you don't do anything and let it sit for like 10 mins? This is to check for overheating as the culprit. If the system still won't power on, then it's a PSU issue.
Once again...

I'll try that next time it happens, although when I checked SpeedFan, all my temps seemed fined.

sounds like a PSU issue. what happens is that when you turn on your PSU, THATs when its drawing in the most energy. what would happen is that your psu is most likely drawing in as much energy as it can, and then when that bleeds off, it probably cant draw in enough power to keep itself going... idk.

Something very similar is happening to me. It all started the day before yesterday when my computer randomly shut itself off, I went ahead and turned it on again. Then yesterday while I was using my computer the same thing happened but when I went to turn it on nothing happened so I opened my computer and I saw that the power supply was not giving any power because the light in the motherboard was not on. I switch the power supply off and on and then I tried again, the computer started but for only a couple of seconds. Sometimes the light in the motherboard will go on and sometimes it won't and when it does turn on it only last for couple of seconds. Today I was trying it again and luckily it went into windows but it didn't last too long before it shut down. I tried it one more time, it got into windows and it haven't done it again. I have a Thermaltake Toughpower 750W.
