[SOLVED] Computer shuts down for no reason

Re: Computer shuts down for no reason

Yes, my system today running a large load is only @ 40C. I agree about the cooling FIN/CPU connection. Use a Q-tip if you are going to clean the old compound off. Don't have it dripping, just damp.

Re: Computer shuts down for no reason

Used to reach 70+ when I started it and 80 easily when watching a vid on youtube.

But it seems to have been fixed by now. I cleaned up everything...no more dust. Re-seated the heat sink. And as dibl recommended (thanks), Arctic Silver 5.
There was a problem with the heatsink as well. Took me 15 minutes to fix it to the MB properly.
Now the MB temp rises to about 37 still, but the CPU is damn cold. I'm getting CPU temperatures ranging from 15 to 18 degrees (centigrade) so far.
By now it would've been around 78.

I just gotta see if the pc still shuts down.
I'll try a couple of movies, maybe some games too and I'll post the new temperatures and will let you know if it still shuts down.

Thanks a lot
ElWray

Btw, that thermal compound rocks. I'm amazed

Re: Computer shuts down for no reason

Double post (sorry)

720p movie doesn't go over 25 degrees when I set it to FFW. It's stable at 22 degrees atm while watching the movie.
No shutdown yet.

I'll edit this post in a few hours and let you guys know if something goes wrong or not.

Again, thanks,
ElWray

There's the actual problem. Your heatsink was not actually pulled down firmly in contact with the top of the CPU. Join the club -- I had the exact same problem with an E8400 CPU. Let me guess -- the plastic pin on one leg of the heatsink split, instead of both halves going through the hole in the motherboard and snapping into place. So you spent 15 minutes pinching the leg together enough to get the whole thing to go through.

Yep, I remember that day well ...

Yep, that was it
I actually had to take everything out of the case. Wouldn't have been able to pin it down otherwise.

Hopefully it won't shut down anymore. (18 degrees atm)

Re: Computer shuts down for no reason

Cool.

Let the record reflect, where Intel instructs you to install the CPU on the motherboard, and then install the motherboard in the case, and THEN attach that nasty LGA-775 heatsink, you actually have little chance of success. You have to be able to see the back of the motherboard to confirm that all 4 legs made it through correctly. Ipso facto you must install the heatsink while the motherboard is out on your (grounded) work surface, with some kind of half-inch thick support under it so the legs have room to snap through. Once I figured out that Intel was publishing B.S. instructions, I've never had another problem mounting CPU heatsinks.

Good work folks!

Re: Computer shuts down for no reason

Yea, some of those Heatsinks are nasty. Some cooling fans are no better either!

Re: Computer shuts down for no reason

I've fought with those Intel fasteners as well. Last time I decided to take the time to have a close look and try to fully understand how they function. After that I didn't have a problem any more and they actually go in and out easily for me. I think the real problem with them is that they are hard to understand. That in itself makes them a bad design in this application.

Re: Computer shuts down for no reason

Wasn't all that hard to understand.
The major problem is that the cpu is surrounded by the MB's heatsinks so it's impossible to see if the legs are pinned in there properly.
I can only check by removing the MB

With all due respect and not to get argumentative, but like many mechanical manipulations you involve not just the understanding of the mind, but the understanding of the body. IOW, you can tell by feel. I spent a decade "understanding" the violin and many times that "understanding" the flute. To me the only practical way to really manipulate a physical device is by feel. I know a very skilled master auto mechanic and he claims to work the same way. Anyway, whatever works for you.

Re: Computer shuts down for no reason

18 degrees? Wow, that is freezing!

I recently got rid of the fan on my heatsink (it was getting unbearably noisy) and the temperature shot up from 36 degrees to - you guessed it - 36 degrees

But it rarely drops below that unless I open the windows and it is below zero outside...

Gotta agree with you on that
In that case I can say I don't fully "understand" it :P

@toad:

18 when idle on kubuntu.
35 idle on windoze 7

That's a pretty big difference.
I tried to force it a bit last night...32 while installing a game in wine, watching a movie and a vid on youtube.
Now there's no need to try the same thing on windows. I'm just installing that same game and it already reached 48

I never measure the temp on my own computers so I'm a little out of date here, but aren't those figures exceedingly good? It certainly looks like you've got nothing to worry about any more.

PS: I didn't think Windows "did" idle. hehe When I see Windows machines I know right away by the constantly blinking HDD light. I can actually tell even if the screen is off. My Kubuntu system only "blinks" when I use it.

Hmmmmmmmmm. Ole, are you still running an ext2 filesystem? Because I think ext3 and ext4 does a "sync" to the disk every 5 seconds by default. Of course, you can change it like I do -- mine syncs every 5 minutes (desktop, not netbook).
