Computer shuts down

When I run Prime95 my computer shuts down not even 10 minutes after I started the program. I saw people running Prime95 for hours without any problems.

It was shutting down in the past and thought it was because the CPU temperature was too high (almost 75 degrees). I just installed a Coolermaster Hyper 212+ and my temperature are around 50-52 degrees at full load. Idle is around 30-33 degrees. So the I don't think CPU temperature is an issue.

I've had the computer for about 2 months now.

I read lots of stuff about PSU temperature, voltage and stuff like that... so where do I start to find the problem? I have CPUID HWMonitor installed if you need data.

Components are in my signature.

BTW I did not overclock any components.

Thanks!

Have you overclocked your 2500k to high? Maybe it isn't a stable overclock.

Yes it could be your power supply, and it should be your first suspect. Test by substituting the power supply with a known good one.

I thought Antec were good for power supplies... is it possible that I have too much stuff for it?

they do make good power supplies, but it doesnt mean the one you got isnt faulty. My vote is either PSU or motherboard problem.

Hmmm thats weird, because i have the exact same power supply and nothing has ever happened. It could possibly be a powersupply problem or a motherboard problem.

Firstly, check the way and why the rig shuts-down. Any BSOD's or just OFF.
Start HW Monitor, and keep an eye on the temps when running Prime95. See and post details here.
Have you checked the memory QVL if not check the exact model number of your RAM with this list

Also check if you have placed the RAMs in the right slots as designated for a 2 X4GB config.

No BSOD's. It actually resets.

My RAM is not listen in the memory QVL. My memory is G.SKILL Ripjaws X F3-12800CL9D-8GBXL 8GB 2X4GB DDR3-1600 CL9-9-9-24 http://www.ncix.com/products/?sku=57953

The RAMs are in the right slots. A2 & B2 like it says in the MOBO manual.

I ran Prime95 many times today. It shut down a few times within 5-10 minutes. I've had a few successfull times where it ran for over 20 minutes without resetting. I stopped Prime95 in those cases.

Everytime I ran Prime95, I did not see any differences in temperature or voltage.

Here is a screenshot of HW Monitor after 25 minutes of running Prime95.

With this type of fault you can speculate about what is causing it until the cows come home. The choice basically boils down to, is it the power supply or the motherboard. The power supply is the easiest and cheapest component to replace so I would try that first.

This is going to be fun... I bought this computer 2 months ago... now I will have to RMA or buy new parts just to try.... grrrrrrrr.... I'll try to get another PSU from a friend or something like that...

I just thought about it, I had to replace my PSU in another computer at the end of 2009. It is an Antec Earthwatt EA-650. Can I just switch my Antec Gamer 620W for that one just to test? I saw there was 3 rails in the Earthwatt... Am I gonna damage or fry something if I use that one?

I ran Memtest86 and no errors for the RAM.

Don't know what to do... no idea how to prove that my MOBO is faulty too... any way to test that?

Do you have any other RAM lying around, that is mentioned in the QVL.... even a single slot will do for the test.
Just plug it in and try the Prime 95...... see if it reboots then.

That's it I'm gonna lose it... I took one DDR3 out and try to run it like that. 10 minutes... computer reset. It's always like that... about 10-15 minutes max and the computer resets.

I thought it was the ram so I set up my whole rig on the kitchen table because I did not want to go back and forth with my tower in my room.

Same DDR3 in the same slot... NO reset after half an hour of Prime95. I stopped the test. Tried in another slot... half an hour without resetting... Stopped the test. I then put both DDR3 like the original setup... an hour without resetting. I stopped the test.

Took my rig in my room... same test without modification... 10 minutes... Reset! Grrrrrrrrr! I thought it was my surge protector so I plugged the computer directly in the wall... Reset again.

Then I thought it was my desk because the tower is stuck between 4 boards so I thought it was overheating. My desk looks like this. Put the tower on top of a little table to make sure the top fan was doing the job but same thing... Reset!

By the way, I can easily play Battlefield 3 without having my computer resetting.

What is going on????

I might guess video card drivers if it were me and I hadn't read the last post.

Antec makes good PSUs, but even they would get old after a while. Not sure how old it is, but with your last few posts I would also think it wasn't that.

All I can think it is now is a heat problem.

When your computer is in the desk, do you have the side panels on like they are supposed to be?

If so, try taking both of the side panels off and leaving it in the desk and see what happens.

Feel free to also aim a fan at the internals while you are doing that since the side will be off the case.

Also, I didn't see if you ran the CPUID thing to check temperatures in the environment where it works, if you didn't could you please do that and post the results like you did before?

You could do the really cool thing and mount the separators on the wood on the desk and go caseless for ultimate airflow. I think I have only ever seen that once in my life.

PSU is only 2 months old. I remember it did that the first week but I was blaming heat problems so I replaced the stock heatsink with a Coolermaster 212+. My temperatures are around 50-52 degrees at full load. Idle is around 30-33 degrees. The panels were on for every test I did. This is very weird!

You have intel hd graphics in the processor. Take out your graphic card and let it run on integrated graphics and see what happens.

It's been running for over an hour now without my graphic card and no reset! I will let it run for a while. The thing that is weird is that it was not resetting with the graphic card when it was in the kitchen.

Alright, it ran fine for an hour an a half without the graphic card. I stopped the test.

I put the graphic card back and ran the test. Reset not even after 10 minutes.

Any ideas what it could be then?

Most probably graphic card is not compatible, need more power (does not sound like because you have powerful psu), or driver issue. Best bet is to try a different brand graphic card such as ati or nvidia.

Reply to decode33

Is it possible my PSU is overheating? My PSU is at the bottom of my case and the fans of my GPU are towards the PSU. I don't know how I could do otherwise though.

Here's a picture of my setup:

I also have two fans at the bottom front of my case drawing air in the case. One at the back getting the air out and one at the top getting the air out too.

By the way, it just shut down while gaming...

Doesn't the case have a vent under the PSU?
If it doesn't, I'd suggest getting everything out of that case , turning it upside down, getting a marker and making holes with a 10mm powerdrill right where the PSU fan might face when you mount it upside down with the fan pulling cool air from the outside and throwing it out of the back of the PSU.

As far as I know, there is not vent under it. The fan at the top of the PSU pulls the air in and throws it at the back. So you think that if I put it upside down, it would help? I believe I have a small gap under the PSU. Maybe 1/2 inch. I don't know if I could just put my PSU upside down would be fine. I already have a fan at the front that is blowing towards the PSU.

If...... If there is half an inch of space under the PSU (which I really doubt) then you can mount it upside down without having to drill in holes. But if there is lesser gay than that half inch then you had better drill holes.

Take a look at this video on Youtube. You can see the gap under the PSU. I think I'm gonna try to put mine upside down. Hopefully it will be cooler and get the air from the front fans instead of the hot air directly from the GPU.

I trust more the top mounted PSUs so I might try just not changing anything and flipping the tower upside down and letting the heat rise and get sucked out by the PSU.

Apparently, there is a fan for that at the top, but it might not be doing its job well enough. In any event it wouldn't hurt anything to try it and see what happens.

The fact that it works fine with no video card in the system does trouble me, though.

If you have another video card laying around, I would try that instead and see what happens.

You may also want to check and see if there are any newer drivers or other people reporting similar problems about the same video card.

Reply to Raiddinn

I just put my PSU upside down. The CPU temperature reached 55 degrees but everything else was fine. I ran Prime 95 for 70 minutes without any problems but finally shut down.

I was also thinking about moving my hard drive and put it lower in my case. It's right in front of my video card and I believe it's blocking all the air that's coming from the front fans.

Sorry no other video cards lying around

Reply to jeffjeff666

It is the right thing to do , turning your PSU upside down. And it will be pulling cooler air into the PSU and throwing it out the back.
Actually a PSU fan has a greater suction area than the GPU fan, when they were both facing one another your GPU fan was not being able to keep up with the negative pressure created by the PSU fan thus was under a lot more strain to cool it, a smoke tunnel would make it look like a whirlpool within a whirlpool but both twisting in opposite directions......
And yes, about that HDD, you really need to put it around the center of the Front intake Fan, that'll help split the airflow and divert it into two direct streams, one going towards the base of the case , helpful for the PSU and one going over the HDD towards the GPU helpful for the GPU.

Of course if the center of the Front intake fan doesn't coincide with the two it doesn't make that much of a difference, you can have the HDD in the topmost or the last HDD bay too, that makes airflow over/under the HDD only but still leave ample air to be used but the PSU and the GPU for cooling.

I dont think its temperature problem. It is expensive card that is why you want to keep it. You can open the case and put a table fan right in front of the graphic card and see if problem is still there

Didn't you read the post to that link you just told the OP to view??? Do you really expect US to advise him to change the HDD or RMA anything?
Read post to other sites before posting links here... the problems between both the OPs is different. They don't even have solution on the other site, whereas his 16X problem would have been solved in a jiffy here.... his bad luck.
Stick with this guys problem. And you don't think temps are his problem????? obviously not.... didn't you see his HWMonitor Screen shot????

jeffjeff you need to do some cable management too.......

Alright, I believe I found the problem. I noticed that my RAM was running at 11-11-11-28 and at 1.65V.

The specs for my RAM says 9-9-9-24 at 1.5V.

I went in the BIOS and in AI Overclock tuner I switched from Auto to XMP and it now it runs at 9-9-9-24 (1.5V)

I've been running Prime95 for 2h30 without any restarts.

Is it possible that I FINALLY solved my problem?
