HELP: Random System Crashes (no BSOD)

Hey All,

I am experiencing some disturbing shut downs on my pc and would really appreciate some guidance. This has been plaguing me for about 6 months now and I can't take it anymore...

Just to be clear, these crashes do not provide a BSOD and therefore no error code for me to research and correct on my own.

In the last two days, this has happened 4-5 times, and most often while watching streaming video online (but not always). Without warning, everything will lock up (sometimes this is accompanied by a terrible sound emitted from the speakers - presumably looping audio from the video i was watching). The computer then reboots itself without my involvement.

Before anyone asks, my drivers are UP TO DATE, and my BIOS is up to date as well.

So far, I have asked around and most people point to my graphics card overheating, or a very dirty (dusty) pc as a likely cause. Firstly, my computer is generally kept very clean, and I am monitoring my GPU temps and they are usually WELL within normal ranges (frankly it runs very cool). I have called EVGA for support, and they told me they had not heard of this problem before. They had me run a bunch of gpu stress tests, all of which provided no clue (they were clean) as to what could be wrong. Someone else told me to make sure my RAM was properly seated. I did check that and I can't see any seating issues.

Any ideas? PLEASE help me! :fou:

Thank you in advance.

It could be a heat issue with the CPU, you said you monitored GPU temps, what were your CPU temps? The max CPU temp is alot lower than the max GPU temp, so it could be overheating the CPU and shutting off the computer especially because videos and such use the CPU more so than the GPU unless you have GPU acceleration enabled.

Other things it may be:
Could be a RAM issue, check your ram with memtest86+ or another RAM tester to make sure one stick of RAM isnt bad. Anything below a perfect score on RAM could cause your computer to intermitantly lock up.

Could be an unstable overclock on the CPU, aka not enough voltage, cooling, etc...

Could be a bad PSU, check the voltages to make sure thay are not dipping below the regular amount, a...

Could be a bad PSU, check the voltages to make sure thay are not dipping below the regular amount, a bad power supply can cause a computer to shut off if it cant give the right steady voltage.

Could be a software issue, or conflict. Might even be as silly as an IRQ conflict which rarely if ever happens.

Could be the motherboard is overheating, if the northbridge or southbridge get to hot it can lead to system instability.

Thanks Mighty. How would I check CPU temps? Would I find any evidence anywhere that would point to this? I do have an aftermarket cooler on my CPU, and I don't overclock so I didnt think of this initially, but it's possible I suppose.

Please advise.

Check your ram settings, looking at your description seems to be bad settings on the ram or cpu, check it is not overvolted and that timings are within manufacturers specs.

You can check the CPU temperatures by using a program called speedfan, CPU-Z, speccy, or coretemp to name a few. If theres air bubbles when you put the thermal paste on, it can cause overheating because the transfer of heat wouldnt be as efficent.

Thanks again. I forgot CPUz did that, I have it installed already. I'll check it as soon as I get home and get back to you!

Edit: Forgot to add that I did not spread the paste myself (Though i do have some arctic silver if needed). It was pre-applied on the CPU fan i bought (Arctic Cooling Freezer 7 Pro REV.2 CPU Heatsink Cooler LGA13).

These values are presumably at their defaults, but I should check.

Can I do all this in CPUz?

thank you very much.

Quick question for you, what tools are used to check a psu? actual v/w meeters or a software? I have an issue on an existing system that will randomly "turn off" essentially. Like some one pulled the plug on it. Once this happens I cannon't restart the computer for several minutes at the minimum. I did a test of unpluging the power cable and waiting 10~ seconds before trying to start it up to see if it was the mobo protecting its self and it still wouldn't restart till i waited for around 5~ min. I would like to note that this issue didn't accure till after I travled from the US to Chile. Problem is present on both power settings, 220 is standard in Chile. 110 required a transformer; us standard.

I don't know if that was addressed to me or not, but I think you missed the part where I said I am in Chile now. No best buys, no Fry's electronics. A link to one would be nice though, as I might get lucky and somewhere in the city a Store might have one.

On a side note... we do have MANY apple stores and some one said that their might be a radio shack or 2.

Mighty,

I have just booted up and started streaming video for about 5 mins. Here is what I see in SpeedFan for temps:

GPU: 31C
Temp1: 29C
Temp2: 25C
Temp3: 25C
HD0: 26C
Core0: 35C
Core1: 30C
Core2: 37C

Try googling PSU paperclip test, that might help you, and you can do it anywhere.

No your all wrong, hes using tri channel kit with a dual channel board, that ram isn't supported. Please purchase the correct ram for your board.

the ram you're using is for a X58 tri channel board and your chipset is a P55

Move along message board kiddys! this geek just solved your highly over looked issue everyone makes so much.

hey buddy.

Had quit a familiar problem very similar to yours. It wasn't actually video, surprisingly it was sound (specifically my Realtek HD audio)

Just to test it out, i disabled my audio via BIOS setup, and installed a x-fi sound card. My Freezing (with the crazy sound) stop. try it out.

Thanks Rozz, I might give that a try. Very good advice.

I want to verify this memory issue first and then i'll try your route.

Thanks Rozz.

I have removed one stick, now down to 2x2GB sticks.

How much of an impact will I see if i ditch my current setup and get 2x4gb sticks (total 8gb)? RAM seems really inexpensive now, the prices are way lower than i remember.

What brand would people recommend?

Mushkin
Patriot

thanks.

Theres really no easy way to test the PSU without having at least a multimeter although by far the easiest way to test is to get a power supply tester. If you have a multimeter then you can individually check the rails by hand. Heres a guide: http://forums.extremeoverclocking.com/showthread.php?t=137886

I wonder if it could be the hard drive going bad too, just another possibility. I would test with Hdat2 or Vivard for any disk errors you can get both from either Hirens boot CD or UBCD(Ultimate boot cd) both are free from their websites.

I have a feeling its a power supply issue but its hard to determine the root cause without actually being there imo. Each computer is unique in some ways of troubleshooting.

Hey mighty,
So those diagnostics for the HDD run off a boot disk, am i understanding correctly? I'll look into it.
