Computer shuts down without warning (loses power

[EvilSaiyan360]

Hello,
I am really stumped, while i eas playing the witcher enhancede edition, the computer suddenly shut itself off. Ithappened twice. I could then browse the internet wothout any problems. Now , today, i continued conducting troubleshooting tests. I was running a scheduled memory test at startup,a and about 3 minutes in, the computer shut off again. I have ruled out the new graphics card, gtx 460 by nvidia, being the problem. The temperatures of the components in the computer are good.( 49 degrees celscius at the most on any component) using hw monitor.When the computer shuts down it tries to reboot but fails over and over again. i have to press down on the power button to shut the computer down. I beleive the problem is either RAM or the PSU

I know the gtx 460 graphics card is not the problem. The cpus temperature is fine too, at about 22 degrees celscius.

I am using a Corsair brand 600 watt power supply. 48 amps 12v single rail

Now 24 hours later, i try to run a scheduled memory test, and the computer shutddown 3 minutes into the test. Is it a bad psu or graphics card?


I know i asked already but i am anxious for more info before i troublishoot any further

Also, when i force the pc to shutdown, i can still see the led lights of the motherboard on

There are no error messages of any kind to warn me of a hardware problem

Please provide your full system specs. As for testing, disconnect the video card and check if the problem persists. Next try plugging your ram sticks in different slots one stick at a time. See if any of that helps.

Hey no problem. Good that you found it out yourself and fast. And yeah, that is really a very careless thing to do. Always make sure all plugs are securely connected. Enjoy.
