Computer turning itself off

10,939 434 June 1, 2018 at 12:00 AM
Hoping someone can help here.

I have a custom built computer I built years ago.

This is the motherboard/processor/power supply/case I have.

Quote :
* AMD Athlon II X4 640 Propus 3.0GHz 4 x 512KB L2 Cache Socket AM3 95W Quad-Core Desktop Processor (Model:ADX640WFGMBOX)
* ASUS AM3 AMD 780L Micro ATX AMD Motherboard (Model:M4A78LT-M LE)
* COOLER MASTER Elite Black SECC ATX Mid Tower Computer Case w/ Elite 460W Power Supply (Model:RC-310-OWR460)
I've updated RAM to 8gb and storage to an SSD with OS and programs installed on it and a 1TB HDD for files.

Computer has worked beautifully since I built it. Until recently. I "upgraded" to windows 10 over the summer. I haven't used it much since then but every time I have the power just cuts out and it turns off.

I know normally this would be an overheating problem. This computer has never had a problem with heat. I can't get it to stay on long enough to actually install a program to display heat, but I have opened the case right after it's shut off and everything has been cool to the touch. I have given the innards a good dusting and confined both my CPU and PS fans are functioning.

I have booted into Ubuntu, but unfortunately my keyboard and mouse don't seem to be compatible with the version of Ubuntu I installed, so I can't do much. However, it managed to stay running in Ubuntu for far longer than it ever did in Win 10.

I have googled and found incidences online about graphics or SSD drivers causing problems. I updated my graphics driver, but crashed before I could get to my SSD driver tonight.

I have probably restarted the computer 2 dozen times tonight trying to diagnose or fix this.

Any ideas?

have u noticed unusual noises prior to powers off by itself? Do u have a spare power supply to test?


how abt that RAM? try to boot with only 1 stick at a time and try all of them, make sure system stays up with each stick... u might need to find out which slot the RAM should be in for 1 stick, 2 sticks, etc.


unless ur life depends on this aging pc, i wouldn't spend too much time or money on old techs. save up for new ones is the way to go hug

No noises. No spare power supply. I have been getting the itch to update a little anyway.

if you want to keep it alive, the PSU would be a good place to start. I'd also look for any bulging capacitors on the mobo.

Started it up again today and it's definitely a heat problem. CPU running at around 80c right at start up with only chrome and the CPU monitor running.

80c could roast a solid steak I imagine. Seems like there are others with the over-heating issue though, you going to try any of the online articles or chalking this up to a dead processor?

So I'm officially an idiot. Ran this by my BIL today and he told me I need new thermal compound. I have no idea why I didn't think of that.

The difference is huge and my problem is solved. My computer has been on for the last 4 hours straight now. Both of these screenshots were just running the CPU thermometer and chrome.

Haha just realized my typo. I meant cooLing ideas. But yes. I imagine 80 is about right for steak.
