    I've recently bought a new desktop and on first start up we had it running for about 15 minuets and it shut down. every time it shuts down the CPU LED light flashes. we have tried a few things but we need help!

    Is this on the motherboard? Almost sounds like a laptop going to sleep or hibernate.

    Is it the one in your specs or another? If not, what make and model or specs.

    Have you tried resetting the CMOS(BIOS) and disabling any overclocks.
    Also, check that the CPU temps... may need to check the CPU cooling systems. (Not on correctly, lack of TIM, to much TIM, fans not working, etc.)

    We reset the CMOS and we are thinking its temperature related so we are getting thermal paste tomorrow because its looking a bit thin and all the fans are working
    And nothing's too warm but it might be set to shut down at temperatures which are too low

    Hi

    Assuming this is the Asus sabertooth 990fx [as this has not been confirmed]

    Enter system bios
    enter bios.jpg

    Hardware Monitoring
    Monitor.jpg
    Look in hardware monitoring at the CPU temps; leave the PC running keeping a close an eye on CPU temps
    What temps are shown?
    Dose the system still shut down after 15 minutes?
    Source - here

    Note: Thermal paste [TIM] is meant to be applied in a thin layer

    probably manufacturing defects. if its under replacement warranty from the seller, i say dont go through too much trouble. specially if its an Asus board. they dont make them like they used to anymore.

    If you really want us to help you, you need to answer our questions.

    so what are the specs of the system you are having problems with?

    Hi sorry yeh we've ran that and monitored the temperatures but it cuts out at about 40 degrees.

    It's the Acus sabertooth 990fx
    I have 2x8gb memory
    And an AMD fx-8510

    It's a second hand system and I tried it before I bought it and it was running find but when I got it home it started to shut down before I could do anything

    Is it giving any BSOD errors?
    Have you look at the "Event Viewer" in the Admin tools for clues?

    Since, it seems you moved the system (I don't know how far or if it was a hard ride)... have you checked or reseated all the connections?

    Have you checked in the "Power Options" to make sure it is not set to shutdown, sleep, or hibernate after a given time?

    Run a chkdsk on the drives for errors?

    If you buy a PC and it doesn't work . Take it back. If you bought is used and cant get your cash back then bench test it. Take it completely apart and clean the dust out

    It doesn't start up for log enough and if we try and turn it on after a break it goes for a few minuets but once it's down if we try again it just shuts down after 5 or so seconds. That's why we are thinking maybe a thermal problem. We've left it in a cold room now and we going to check again in the morning to see what it is like.

    Sounds like it is getting worse... yea, I think it may be time to look elsewhere and take that one back.

    Do you think there is anyway to salvage it or does it sounds more like a hardware problem?

    You can salvage just about anything that is not a burnt piece of rubble; but, the question is... How much time or money do you want to sink in it?

    Yes its hardware related. You just need to figure out which hardware. Which is time consuming and requires testing parts. Otherwise its a guessing game. Could be the power supply, board, short in the case, heat sink not aligned properly, GPU or memory not seated properly.

    Well, if it is just a project and you got a good deal; then, go for it.

    I would start by doing a little troubleshooting and if that did not help, I would go to full tear down and rebuild/testing mode.
    It would help if you have another system and extra known good parts for testing.

    Good Luck on the project.

    its a crapped board and someone got rid of it. asus boards are pretty crap nowadays even flagship ones like sabertooth which is supposed to be built for quality..

    its a thermal issue, but with the onboard vrm of the motherboard, but not the cpu.
    as it runs and gets hot the soldering joints have cracks which become bigger and then the soldering fails.

    you might try reflowing the solder by running a hot air gun over the chip. but its not guaranteed to work.

    woohoo... before taking asrock for my board i considered take sabertooth board
    anyway, maybe better you take everything off from the case for further inspection. it could be from board, heat or psu.
    if you have any spare hardware you may test it with that

    We took the CPU out and gave it a clean and applied some thermal paste now it's working fine. Thanks for all the suggestions
