    For the past 3 months my PC has been mysteriously shutting down (turning off) in the middle of use, after boot, & at non repeating intervals.

    I replaced the PS... still failing.

    Today I analyzed using RealTemp & Fan downloads to see I was running way to hot. Cores running over 100 degrees regularly.

    System Snapshot:
    Win7 Ultimate
    Intel Core2 Quad CPU Q6600 @ 2.40GHz
    4.0GB RAM
    NVidia GeForce 8800 GTS
    Case: Armor 4 fan tower as pictured

    This was a custom build from a work friend & FAR too powerful for the internet/email/excel & word work that I do. I made the problem worse when thinking the shutdown problem was PS related, I put in a new one & had to disconnect the top fan to fit the new PS. But this is not root cause as the problem existed prior to this mistake of mine.

    Now: What to do? I have a Vornado from Target (pictured) shooting into the open side of my PC (temps under full load now high 80s!) & I just completed the same test (a virus scan) that caused shut down before, confirming that HEAT is indeed the problem.

    That is great news for me to know the problem. Im looking to some experts out there to help me identify a good solution. Please recommend specific set ups & products. Thanks for ANY help. :rockout:

    Hmmm, do i see a layer of dust build up between the fan and the heatsink on the cpu? Had that happen to my cooler I had on my E6420.

    The dust caking the bottom fan of your case, in your second picture, may point towards some of the problem. Clean out the cpu heatsink fins and fan with compressed air, and make sure the fan is actually working. Problems like yours are usually an easy fix, since your rig has been up and running for a while, and this problem has just occured. I would clean stuff before moving into more elaborate things like removing the heatsink and reapplying thermal paste, or an aftermarket cooler.

    Edit: Mastrdrver beat me to it while I was typing!

    Take the cpu heatsink off. Clean the thermal paste from the cpu and the cooler (wipe the excess off, then use isopropyl alcohol). While you have the heatsink off, give it a really good cleaning. You can probably remove the fan from the heatsink entirely by unclipping the fan from the heatsink... there should be plastic tabs that hold it on to notches cut in the heatsink. A philips screwdriver would be helpful... that way you can blast the heatsink out with the fan out of the way. Blow the fan off too. The fan should clip right back on. Then, re-apply thermal paste. Here's a guide about how to apply thermal paste: http://www.techpowerup.com/printarticle.php?id=134 Temperatures should drop siginficantly.

    If you don't already have thermal paste, MX-3 is just about the best out there:
    http://www.frozencpu.com/products/9...mance_Non-Conductive_Thermal_Compound_4g.html

    You could also go for the cheaper, only slightly less effective MX-2 (expect like a degree or two more... not really a big deal)
    http://www.newegg.com/Product/Product.aspx?Item=N82E16835186020&cm_re=mx-2-_-35-186-020-_-Product

    Here's a great aftermarket cooler if you wanna go that far:

    clean the fans and the heat sink and if that doesnt do it... take the heatsink off clean it and apply some decent heatsink compound

    Thank you to all of the above suggestions.
    Id like to stay home from work today & try these fixes but I cannot.
    Ill check back in 24 to relay if this worked, after I acquire all of the tools.

    To add a bit more detail here in case this is referenced by others:
    Another odd outcome of the random shutdowns is that I lose my login status to my google home page & forums (this included). Odd that I dont lose any others: AOL, etrade, etc.. Normally they remain stored in memory of my browser. Not sure if that is a cache or cookie flush, but odd.

    ADDITIONAL QUESTION:

    Gents:
    I will try all of the above actions to cool down the Processors.
    BUT: what about "under clocking"? I have WAY too much power for what I do (as you can see from my config). Is there a way to reduce performace of by quad core, still have a good use experience, & reduce this overheating issue?

    In short: yes
    although you'd be better off replacing the CPU cooler with something better/cleaning it out thoroughly.

    If you decide you do want to overclock, go into bios and drop the multiplier a bit & the CPU voltage.

    Although, under what conditions does it hit 100 degrees? If it's doing it without you doing something extremely intensive then whatever the problem with the original cooler is it's pretty severe.

    Underclocking will not fix your problem. It's obvious to me that the person who built the machine did NOT apply the heatsink properly, and/or is giving the processor more voltage than it needs. Take the heatsink off, clean it (and the processor heatspreader) with 98% rubbing alcohol, place a pea size amount of new thermal paste, then reinstall the heatsink. Make sure it is on tight. After you've done this, we can walk you through checking and adjusting the voltage in the bios.

    Was happening any time it would access the HDD repeatedly. In my case, a Kapersky full scan would get about 65% done before shut down. Using RealTemp I found that the CPUs were all at about 110 before shutdown.

    Is that really bad? I have no scope or scale for reference.
    With the side open & the Vornado running the same scan ran at about 85 degrees.

    Im going to take this action tonight.
    Getting paste & air at lunch today.

    Another interesting note: My rig has always run hot, ie: the room would get warm from it. BUT I had no problems for the first 6 months other than discomfort of the room. Ironically the room is less hot now & I am having the problem (it is winter as well & possibly the heat is not dispersing b/c its overheating internally thus the room is not as hot but the CPU is hotter)? Interesting detail, but ultimately the issue is what it is.

    Yes. It is REALLY bad. It is above Intel max spec, and it will kill your processor soon. You NEED to get that thermal paste and take care of this asap. Honestly, considering what you are doing with the system, there is no reason for you to ever see over 65-70c, ever.

    I hope you are meaning 100 F and not 100c Because if its at 100c im suprized you even have a working computer :laugh:

    And at TPU we always say, Nothing is ever to much for email/desktop/pr0nz.


    Overkill All The Way!!!!!!!


    Also, Just go to office depot, get some air cans, spray the heatsink down once in a while if dust plaque you that much, Also, get to fixing that, but taken the heatsink out, clean it, Make sure the fan is pluged in the motherboard and running full speed, and then when putting it on get some aftermarket thermal paste from www.newegg.com you can get tx2-tx3 or artic silver 5, whatever floats your boat, and put the heatsink fully on the cpu, and make sure it has pressure on the processor, then go ahead and tear those EMAILS UP.

    Noted & Thanks.
    Very much appreciate picking brains here.

    Im familiar with CE products, not with PCs specifically.
    Lets assume I fix this problem today.
    Ive already gone through about 50 shutdowns for temp.
    Do I need to be concerned about residual damage done? Is there a diagnostic/benchmark tool I could check out my rig with to see?

    I will get this issue behind me, but Id like to know what Ive done & what I have left.

    If it hasn't died yet, you might be ok. These processors are pretty hardy, but it will die if you do not fix it now. Don't be suprised if your processor heatspreader looks burn't when you tske off the heatsink.

    I would assume since he was using Realtemp that it is in celcius. Realtemp uses celcius by default.

    When a computer crashes out it does a memory dump.
    That will cause it to forget some of your login and password info sometimes.

    also 100-110F would be perfectly healthy :p

    Have you checked that the fan on your CPU cooler is actually spinning/working correctly, and cleaned everything out?

    Otherwise it's remounting time.
    In your position I'd go for a new cooler but that's just because I'm obsessed with performance :p

    He does not need a new cooler for what he's doing. He just needs it seated properly, with some better thermal paste.

    Yeah, it wasn't a suggestion, it's just probably what I'd do :D

    Standard intel cooler, if working correctly with some MX-3 or whatever would keep that thing cooled down nicely.

    I don't think the issue is with seating, especially not after hearing that it ran fine for 6 months, heating up the room, but now doesn't heat up the room and crashes.

    These Intel coolers get clogged with dust very easily, I can almost guarantee that is the case. I bet the fan sounds louder now than it did at first also, because it is trying to push more air through the cooler, but can't because of the dust. The front of the case being covered in dust where the fan is also points towards a dust issue.

    I bet a good blast of air would fix the problem right up, without the hassle of a reseat. I'd try that first, and only do a reseat if that doesn't work.

    I've never seen temps like that out of a dusty cooler in that short amount of time. Now maybe if the system was running for a couple of years or something. Still, not a bad idea to try it...though I don't think reseating a HSF is much of a hassle. It might actually teach him that he could be able to build his own system. :)

    Im going to take these steps in the order of magnitude suggested above.

    Inspection
    Air only
    Reseat w/ Paste
    Replace parts
    Etc...

    Ill reply back with results as they come.

    As for building my own rig next time: not going to happen! Im buying off the shelf next time & going to stop pretending Im still in college! That said, I give myself credit for swapping the PS that was a complete ocotopus & pulling that off successfully. :)

    LOL. Good luck man. I guess I just assume that everyone would enjoy building once they get the confidence to do so. Bad assumption, I know.

    I have, in really dusty environments, or environments with lots of pets, especially long hair dogs/cats.

    I've got 4 dogs and a cat, and if I don't clean the fan filters on my main rig every few weeks, they get so clogged with their hair that everything inside starts to run hot, my GTX 285 will hit 90+°C from just folding. If it wasn't for the fan filters, I'd be cleaning that gunk out of the heatsinks...

    Judging by the amount of dust on the front of the tower, I wouldn't be surprised if the heatsinks were just as dusty and gunked up.

    And taking off the Intel heatsink, with the stupid push pins, is a hassle...:D

    For the record:
    I am going to clean with air & paste tonight (assuming OD still has it in stock).

    & Ive ordered the buff aftermarket heatsink referenced above & the arctic paste.
    Dont care if Im Duping efforts.
    I want to know for certain that this issue is resolved & my PC is too important to not spend the extra $30 on it for a clean conscience (if nothing else).

    Spoiler Alert:::: Now that you metion it, I HAVE seen black ashy looking marks on the MB near the processor. That is a terrifying site. Cant wait to fix this tonight. Will report back.
