Computer issue

[Forrest_B]

I built my pc earlier this year, and today it has been acting a little bit funny and i'm not sure what could be the issue.

 

So what's happening is my monitor will lose signal from my computer (plugged into a 980 via DVI), my keyboard will go dark and turn off (k70RGB), and my motherboard had a temp indicator/error code display that shuts off as well. The light around my case power button goes out as well. Everything else in the computer appears to be running though, my fans and h100i all keep ticking. I'm not really sure whats happening. It has happened twice today.

 

Any ideas? If you need any more information let me know.

is it overheating?

[Potato_Slayer]

it kinda sounds like the computer restarted.. what was the motherboard error code?

[Nicko_barbeque]

do you haave enough power to run all hardware? how many w powersupply?

[Forrest_B]

No, both times i've been doing nothing but web browsing

It sounds like it might be a power supply issue. I'm not an expert but it sure sounds like it.

[Forrest_B]

There was no error code that I could see, though the led indicator went dark. Power supply should be fine wattage wise, It's an RM750 and I have an i5 4690k @ 4.0ghz and a 980

Doubt it is a powersupply issue if the fans are still running, if it was a PSU issue you would get an instant hard shutdown due to loss of power. It may be a motherboard issue though, maybe check for a BIOS update first off

Could it be some kind of protection? Maybe a power surge occurred

It could be but I still doubt it, what error were you getting?

[Forrest_B]

Okay,

So my motherboard did have a bios update available, and I just updated.

The update went through fine, however when my computer restarted it powered up and immediately back off and did that a couple of times. I flipped the power supply switch off and back on and it booted up fine.

Not Getting an error code because when it happens the error code led goes out

I'd be a bit surprised if that was all that was causing your problem.

Me too, just want to make sure I exhaust all options before I look at RMA.

[Forrest_B]

Its hard to tell if the issue is solved because it doesn't happen frequently. It happened once this morning, then I went to class for a few hours and came home and was on my computer for about 2 hours before it happened again.

Can you plug in a device like a battery bank to charge from the motherboard then open a graphics intense game to stress test the motherboard. I suspect it is definately motherboard related. However it could be as simple as a loose connection getting jarred at random times. Maybe you shake your leg or kick the table. Try to shake your computer a bit to see if it triggers an event.

Just ran the witcher 3 for ~10 minutes. Didnt have a power bank but plugged my ipad into the mobo. Didn't have any issues. Would a loose connection cause only certain aspects to turn off like that? My apartment does have a bit janky power sometimes, and my power strip is near my feet. It's possible that I may have bumped it.

[Forrest_B]

It just did it again. I Just plugged my PC into the wall directly to see if that helps with things.

[Forrest_B]

Alright. Ill keep time between the next time it happens and the time after (if plugging into the wall didn't fix it) and report back what I find. Should be sometime tomorrow...

Thanks for the comments.

 

If anyone else has any ideas as well feel free to toss them around.

I'm pretty sure its either a power issue or a motherboard issue.

 

Appreciate the help

When my computer boots the motherboard shows codes B2 9C and A2 if that helps with anything.

You should time the instances and see if they occur within a set period of time. Aka 20 minutes-40 minutes etc... I want to know if you can predict failures by time of operation. I recommend turning the computer on letting it run netflix or something and watch until it cuts, then write down the time. I'm hoping that since you have it plugged directly into the wall it'll resolve your issue.

Was running well for most of the day...but just happened again. On for 3 hours 45 minutes no issues then poof. Then It just did it again two minutes later. It doesn't seem to have any sort of time consistency. Anyone have any ideas?

Are you sure all the connections to the motherboard are secure? Check everything for loose connections and for damaged cables. Check if all the components are updated

Hi there and thanks for the response. I just checked all of the cables and did notice that the 24 pin wasn't perfectly seated on the PSU side. Fingers crossed that that solves the issue, though I did have the b2 and a2 post codes when I booted again. It boots into windows though as it always has...

I made sure all my peripherals and everything was updated last night including the motherboard so that didn't necessarily help. Will report back later my findings. Appreciate the comment.

Well, my computer seems to have made it through the weekend without an issue. Hopefully it keeps up, but everything seems OK. Thanks everyone for the advice and help, you are awesome
