CPU crashes randomly

Hello,

my computer randomly crashes. I do not know where to start troubleshooting from. I also do not where to get an error log from. The only effect i observed after the crash is that the fans switched off momentarily and are switched on again but the system is not booting...

how do I know what's wrong? cud be psu/gfx/processor?

SATA II HDD
8GB DDR3 1333Hz DRAM x2
i5-2500 @ 3.3Ghz

    i spend most of the time gaming. but there are instances that normal web browsing it crashes too
  4. Most of the time, when a computer can run games for a while but still spontaneously reboots while idle, the PSU is usually (part of) the problem.
  5. hmm. so how to directly identify and confirm it as a problem? What steps should I take from here?

    i played l4d2 for 2 hours, it seems fine. played bf3 and it crashes. but there are also random times it crashes while doing nothing.

    is it an overheating issue?
  6. The easiest way to see whether or not the PSU is the problem is to swap out with a known-good PSU from a better brand than CoolerMaster.
  7. thanks for the suggestion. but i do not know if it's the PSU fault yet. and i can't really get my hands on a better PSU w/o buying. I don't want to end up buying a new PSU to find out that it's not the problem. just a question, is it possible if the graphics card is experiencing overheating issues, it will call for a restart?
  8. Best answer
    If the computer reboots while you are browsing web pages (which means practically idle), it is unlikely that either the GPU or CPU is overheating.

    You could use HWMonitor to see how warm stuff is but if heat was the problem with your idle-reboots, I would expect the system to systematically reboot as soon as you start any game.
  9. Edit 9:49 GMT+8 = Power surge detected! reflected on my mobo when it restarted.

    one new symptom. once it restarts i see the red LED on my DRAM lit. Manual of my mobo here: http://www.manualowl.com/m/Asus/P8H67-M-LE/Manual/275839?page=43

  10. Well, since the motherboard has protection circuitry to detect and report bad power from the PSU and shut down the PC when it does as it seems to be doing, that would be one more reason to suspect your PSU-shaped object from CoolerMaster.
  11. on another hand, my gfx card requires 2 2*3 express supplementary power connector.

    initially, my current psu only has 1. the technician added one more for me. so does that mean my psu is underpower now? Is it ok for me to just use one 2*3 express supplementary power connector for my gfx card. will it cause hardware failure overtime?

    i don't get it that everything works ok at his shop and it becomes nasty and problematic at my place.
  12. Your PC should use less than 300W which should technically be well within a reasonable quality 525W PSU's capabilities.

    If the PC works fine at the shop but not in your home, it could be that line voltage is lower than the shop and this could be enough to change a borderline PSU's behavior.
  13. These issues are well reported at the Windows 7 Event log -- usually as Kernel-Power issue.

    Go to start > Control Panel > System and Security > Administrative Tools > Event Log

    See what it says -- it says the date and time the issues happen, then post it here for further appreciation.

    The only difference I believe between the repair shop and mine is that they have air conditioning. Mine's just normal ventilation. or the other case, is that my pc is trolling me.
    and is CPU fan running at 2000 rpm normal?
    also, if my gfx card requires 2 6pin supplementary power connectors, can i just run with one?

    i'm sorry i'm at work now and can't access the event log. i'll post here when i get it.
  15. ~2000RPM for the stock HSF is normal.

    If the GPU has two 6-pin PCIe connectors, it usually requires both for normal operation and the box often includes a molex-to-6pin adapter to accommodate PSUs that only have one 6pin PCIe power cable. This gets the job done assuming the PSU is of good enough quality. Problem is that CoolerMaster is generally considered a sub-par PSU brand, which means you may very well be on the wrong side of the quality curve.

    on the otherhand speedfan showing that one of my fans are running at 6000rpm. The 2000rpm value i quoted was from HWmonitor
    which of the following brands in my market would you recommend then?

    Corsair, Andyson, Antec, HEC, Seasonic, Thermaltake, FSP
  17. Corsair is generally fine, Antec too. Seasonic is one of the best out there. On the FSP side, their Aurum series is good but expensive.

    You can go browse hardwaresecrets and johnnyguru for more inspiration and get an idea of how good/bad each brand tends to be and how bad/not-so-bad each's weaknesses are.
  18. Corsair, Seasonic, Antec, FSP.
  19. the repair shop told me, after i told them my pc symptoms(power surge), that i should do a reformat and clean installation of windows and check again. is this valid?

    2nd step is that after the reformat, i would be able to determine if my mobo is overheating. As i recall, the only difference between their shop and mine is that theirs is air-conditioned.

    should i follow their instructions?
  20. Power surges are a hardware problem. It is highly unlikely that re-installing the OS will help that in any way.

    No need to re-install the OS to check whether or not your motherboard is overheating either, just need to look at max temperatures in HWMonitor and you'll know - assuming HWMonitor reads your board's SMBus properly.

    When you have a flaky PSU, every little bit is susceptible of making or breaking things. When people call CM "CrapperMaster" because most of their PSUs fail hot-box tests at 50C, CM responds that their PSUs are only rated at 25C. This is a rather pathetic excuse since a PSU will rarely get to run at less than 35C under remotely significant load, particularly in a top-mount case.

    You can follow their instructions if you want to shut them up but my bet is that you will be wasting your time and get the same results.
  21. alright. thanks for the advice. before i get my spare psu, i should get the kernel power issue checked right? as suggested by jenm

    i see a lot of events but can't pinpoint which is which. do i look under hardware events?
  23. Event Log will not not tell you a lot -- usually it points out to an online page that will not help you at all.

    The point in having a look at Event Log is to make sure if the crashes are related to a power issue or not.

    One thing you could do before you get a brand new PSU is to go to the shop and ask them to test your system with a different PSU, but it seems that the shopper is not very keen to help you, which is very typical.

    Not much point in doing that since according to OP, the system runs fine with the current PSU when the repair shop tests it.

    There are at least three variables that may be at play there and causing the CM to work at one location but not the other:
    1- site voltage
    2- site wiring
    3- temperature
  25. just bought a new psu. FSP raider 650W. so far so good. will post back. I went for it cuz i read quite a few threads and it all seems to be pointing towards psu. shd i get the other faulty one checked? since it's under warranty.

    Sure, if shipping is covered by CM or your local shop has some sort of free/cheap arrangements for warranty service. If you are lucky, you might end up with a working spare PSU instead of a wobbly paperweight.

    According to your response to my post a brand new PSU will not solve the problem, eh?

    A brand-new higher quality PSU should:
    1- have better tolerances to input voltage fluctuations
    2- have better tolerance to wiring faults (although such faults if applicable really should be looked into rather than glossed over)
    3- have better tolerance to higher operating temperatures

    Your existing CM PSU might be operating fine by CM's QA standards but fail due location/build-specific conditions. A good PSU should not be that touchy/flaky but this may (or not) be standard for CM.
  29. Regardless, the CM Extreme2 is not a good series.

    I guess for normal gameplay is alright. I was previously using Radeon HD 66XX GPU without the need of supplementary 6pin connectors. and it was fine

    then i bought the current gfx card which i think it over-stressed the PSU for around a month while playing bf3?

    well, the thing to consider is i'm not sure if bf3, over the past month, released anything that increase tax on the GPU, thus affecting PSU?

    The more likely explanation is that gaming on the flaky CM PSU accelerated its aging until it became too borderline to continue working well enough to keep your other components happy.

    It is not your PC's power requirements that went up, it is the PSU's capabilities that got worse due to poor design.

    I see. Are you an advocate against CM? haha

    If you stick around the forum for a while and read threads about boot-looping, mysterious rebooting, etc., the PSU ends up being the cause something like 90% of the time. I have personally owned and repaired many cheap PSUs over the past 10 years and it can take as little as $2 worth in parts to turn a piece of crap into something stable that will last a long time. If the manufacturers used similar better quality parts off-the-bat, those improved PSUs would cost less than $0.30 more to build.

    I'm not so much against CM as I am against any manufacturer cutting corners worth less than $1 on a $50-500 device that spells the difference between something that will die within months or soon after the warranty expires and something that will last 5+ years. I would much prefer paying $5 extra up-front ($4 extra in the manufacturer's pockets) and not have to spend $2 on parts and a few hours to disassemble+reassemble to repair those devices later while they are still within what I would expect to still be within their useful life... when I bought my cheapo 24" LG LCD, I was expecting to use it for 5+ years but I had to re-cap its PSU because it was starting to fail at turning back on from standby during its second year.

    I hate when electronics fail due to excessively greedy corner-cutting. Stuff like LCDs that should have a very long useful life should carry a minimum warranty of 3+ years. This is a lot of unnecessary and easily avoidable e-Waste.
  34. They're very "unstable," leave it at that.
  35. Cooler Master does not make PSUs of course. They buy PSUs from various companies. Some of the designs they buy are bad, and some of the labels they use are false.
    It's possible to buy a decent PSU from them, but usually when they sell one they want too much for it.

    So yes, you will find a lot of prejudice against CM PSUs... but then we are always recommending their cases. They even sell reasonable cheap case fans.

    And as the article mentioned I think, CM PSUs are sold EVERYWHERE. You can find those cheap PSUs in countries where the only other PSUs are actually WORSE. Although, usually in those areas FSP has some better offerings.
  36. I guess it's really the PSU afterall. Just a side question. should i install another chassis fan to my system, how effective would it be to reduce my cpu core temperature? and how do i connect the power plug to it?

    my cpu temp hit 70 deg while gaming. i know it's not the threshold but is it a bit too hot?
  37. kChaste said:

    If you are using the stock HSF without a rear exhaust fan, 70C might be normal.

    If you have no rear exhaust for the CPU area, that would be the first fan I would add, followed by front intakes if you have any vacant spots there.

    If you still get around 70C, you might want to re-install your HSF or go aftermarket. While CM sells many lousy PSUs, their inexpensive Hyper 212 EVO ($28 on Amazon) is one of the best budget HSFs money can buy out there... if it fits in your motherboard/case/RAM configuration.

    hmm... every CPU has a HSF system right? I do have a rear exhaust fan underneath my PSU. I guess I can install a fan underneath my DVD drive, which is a space between my hard disks and the DVD drive. is that a feasible spot? what about the side casing which can be slide apart? can a fan be installed there as well?
  39. 70C for an i5-2500 under load is normal, just do not let it go over 72.6C, which is the max temp for your CPU.

    I´d get the Hyper 212 EVO InvalidError suggested you tough -- it will make things cooler -- and yes, definitively get those cases fans installed -- you won´t regret that.

    the difference between 72.6 and 72 is very close which worries me. Btw, how did u find out about that? I thought the threshold was 98 deg iirc when i saw at the BIOS screen.

    Btw, would it void my warranty if i replace the stock HSF?
  41. "Feasible spots" are where the case has mounting holes that allow fans to either bring fresh air in or blow hot air out. Cases usually have at least one side-panel fan mount and some combination of bottom and front fan mounts. Those 3-4 locations are usually configured as intakes.

    If your rear fan is already configured as exhaust, your CPU shouldn't be hitting 70C unless there is a mounting issue with the HSF or you are overclocking. But 70C is not really worth worrying about (yet) so if you do not really feel like messing around with re-pasting the HSF, you can leave it as-is for the time being.

    alright. that's cool to know(no pun intended). I realise there are several modes my mobo can run at BIOS. like silent, standard and turbo. The graphic difference displayed between the modes shows that only noise increases. Does these modes actually make my HSF run faster(more cooling effect)?
  43. 72C is the max package temperature while 98C is the max junction (core) temperature.

    As for replacing the stock HSF, there is no warranty problem with that but you need to stash the stock HSF somewhere because you have to send it back with the CPU if you ever need to do an RMA on it.

    While I'm not sure where these numbers come from, they sound about right. However, I don't think they tell the whole story. I'm seeing memory related errors from CPUs that are hitting somewhere in the 70's max core temps. (well, mostly on IB) And, 70C while gaming is far different than 70C under full load, say Prime95.

    so i should be slightly concerned about it? how long does a full prime95 test run?
  46. Forever, but generally you don't need to run it long. More than anything else, it's used to test temps and overclocking stability, If your CPU is air cooled it will hit its max temps in a minute or three.... always run Prime95 with a monitoring program running first. Real Temp or HWMonitor.

    Be aware that you have to tell it to exit... closing the window in Prime95 just minimizes to the system tray.

    alright. Thanks for the info. I'll try prime 95 and post results here.

    on a side note, I happened to click the link on your post about PSU guide. and i realised that 525W EX2 CM PSU only has like 480W based on the calculations mentioned on your thread and it is not sufficient to feed my GPU.

    http://www.coolermaster-usa.com/product.php?product_id=3082
  48. The specs they claim don't mean anything. I'm fairly certain the PSU won't deliver even 480W... but your system doesn't actually use more than 300W.

    Not sure what calculations you mean... A 6850 overclocked still only needs about 160W, and the rest of your system much less than that.

    You just need to understand that there are many other factors in evaluating a good PSU. When you get gas at the pump it doesn't make any difference what the listed octane is, if there is water mixed in.
  49. Hi Moderator, I would like to state that this thread's problem is solved.

    I was just manipulating the calculations of Voltage X current = wattage as your thread suggested.

    Ok, just ran prime95 for a short while and am registering reading of maximum of 85 deg C on core #3.

    so... please advice further.
