Ahhh Overheating When Cooling Is Fine???wt-heck???

Hi,

Below in my sig thing, is my system spec's, that's what's running off this motherboard.

http://support.gateway.com/s//PC/310...520218nv.shtml

And in this case...

With This mess of cables that works (note twist ties if u can see closely)

http://img.photobucket.com/albums/v4...p/DSCF0003.jpg


This is the problem.


I'm at the pc for awhile, ho hum, playin WoW, or doing video editing. Some heavy cpu things, or just solitaire. I walk away, or go away for a few hr's (errands, etc).

I come back, the pc's off. No biggy, I think someone else turned it off, or the power fluctuated and as I told the bios, keep it off. Simple right? Nah...

So I turn the pc on, and low and behold it decides to turn itself right back off half a second later. *scratches head*????

I turn it back on, and I get this new black screen, dos text saying HEY, YOUR CPU OVERHEATED AND WE JUST RECOVERED FROM IT.... ***???

The bloomin fan's were on like always, the cpu i'm betting was flat out cold when I started it in the first place... ***????

That's round 1. That was a few days ago.

Today, i've been off and on again gaming, nothing much... (Been sick from work, cold/flu, gotta hate it naturally, just a gut feeling eh?). After a bit, I decided to get dinner, go watch a few hr's of good old tv' shows, etc. And came back, and I know for a fact, no one turned the pc off.

I was curious, is this a repeat problem? or what? Hmmm,

So I figured, hey what could go wrong other then me bring a sledge hammer to it....

I turned it on, and :O WOW It turned right back off! AMAZING! A power button that's designed to shut off right after u turn it on! Awesome prank! But it's not april fools.....

Now after all this annoyance, I kept it off, RE CHECKED all cables, RE CHECKED that the cpu cooler / heatsink WAS ON IT..... (Confirmed carefully). Made sure all cables, power, usb...(why not), sound, pci card's (3x), ram (2x512mb). And hell my harddrives are still around 26-28 celcius .

Anyways, Other then the fact I bought the pc ORIGINALLY in 2003 october, and i've got a LOVELY 5 year warrenty, what are the CHANCES i'll be getting a "replacement" motherboard, and are there ANY other suggestions? Especially since the BIOS is unable to be overclocked OR underclocked AT ALL.....

The top of the post = links to motherboard, case, details, etc... Below is sig / pc specification information.

Ok, Firstly If possible are you able to turn it on and go into the BIOS and go Under ''PC HEALTH STATUS'' to check what temps you are really getting ?

If not that sounds like a Dodgy PSU.

However before we say that make sure that your CPU FAN has its 3PIN connector in the Motherboard as your motherboard will cause a system shutdown if no fan is connected...You can disable this feature in the BIOS also.

Try that..If not report back here.

Thanks for the reply, but unfortunately I believe I have the most limited bios in the history of bios's as of 2003. (prior to that, dunno). Lets just say I get to see what's plug'd into the computer (hardware), fan's, no control there, pc health, NOTHING for that ODDLY. Hell I can barely turn usb's on/off or the onboard agp (INTEGRATED) off... so I can use my 2 pci video card's. And onboard sound, even though disabled there, AND in windows, it thinks I have to install it still....

The 3 pin connector (the little fan cord from the top of the cpu fan cooler) is thoroughly plug'd in. The pc turned on fine this afternoon (saturday), and I listened for it.

I've aim'd a flashlight at it to watch it over a 10min period (bored but worth it) and it didn't even fluctuate, however it's possible that a ROUND IDE CABLE that I used may have physically over time pushed it, so i'm going to try and re locate the cables carefully so as to clean up the "mess" a bit, but also not put any pressure on those "key" cable's to keep the pc running. However, i'm also trying to have no cables on top of the cpu fan assembly also, which is doubly a challenge in this pc case as you can see in the picture.

The case is a mini tower, not even mid worthy. But hey, it works at least. And it's doubled in weight ever since I added the extra pci card's, the new cpu + a better heatsink/fan then it's original. And stuff like that. Practically everything IS NEW (over 1 year approx) compared to the mobo and case itself, and the original dvd/cdrw combo drive.

Side note, to backup the pc in the past (until I recently did get a dvd burner), I originally backed it up with 20+ cd-rom's, carefully catelog'd and labeled what's on what, etc....that was fun... and unique. But it worked .

Anyways thanks for the help, i'll definately look for the cable there.


One thing I DID TRY was to see if it would run better without the 80mm fan's using the power on the line for the cd-rom's (the harddrives were on a seperate molex line so that incase the cd-rom one was overtax'd it wouldn't affect the harddrives). Though i'm definately going to have the fan's soon permanently on via a 200watt psu I have eventually.

With respects and thanks,

Le_Loup

Ok I just checked the cable, and watched the fan, then the pc turned off during boot. ***? This is really annoying me, i'm in windows now like there was no problem. But it turned off after loading half of windows xp! O_O

Now the FAN DIDN"T STOP until the thing turned off.... naturally... BUT it was going fine!

How do I reset the sensor's or whatever? Because it might be something faulty there, but my bios, is so limited, it's freaky!

Truthfully? This is a pre-built system with a warranty......I would contact them and make them fix it. Although, most places your warranty is void if you break the seal and open the case, so that's not likely an option......

The only thing to do is test each component separately to try and diagnosis the problem one. Might be hard to do if this is your only system. If the fan is still spinning though, and this just started happening, it seems unlikely it is actually an overheating problem. Does it continue to say CPU OVERHEAT when you reboot now, or was that just the first time?

First thing I would check is the PSU. If you can get a spare PSU to plug into the system and test it that would be a good first step.

Worst case is the CPU itself is damaged.......

Ok, fortunately it's running enough to actually open up overclock and read what you said.

I had the pc powered down overnight and the power button at the back switched off so as to have 0% power running at all in the case. Pure cold boot this later morning (sunday).

Re: Cpu overheat, it literally says it just recovered from a cpu overheat, but not sure what else though it'll say other then my general stat's, ram, whatnot, (weirdly), then it says press F4 to continue, F2 for bios, or F10 or F8 was it... for the boot menu.

What my next test/plan of attack on this annoying thing is... Simply turning the pc off, giving it some time, then taking the heatsink off the cpu, completely cleaning it (compressed air), and taking the thermal paste off the bottom of it carefully. And also wiping all original thermalpaste if possible off the cpu (carefully with cardboard or something). Then removing the cpu, and using compressed air in the socket AND on the cpu pins to clear them up. (possible dust buildup). Then... i'll re apply the thermal compound (I still have some), and i'll try and put it all together and hopefully it'll work....

*here's hoping*

Sounds good, but use alcohol to clean off the paste, not cardboard. And not some random vodka you have around LOL, something pure.

God luck.....let us know how it works.....

Fyi, right after I did that post... the last one... my pc died... last night, (overheated oddly).


Afterdoing some serious looking at the durn thing. Here's the scoop. Oddly the previous thermal paste somehow ooooozed beyond the cpu and onto the outter rim. The Cpu HEATSINK I have, surprisingly didn't seem to have enough, or oddly didn't stick to the cpu all to well. I think it literally... if it wasn't hook mounted, would have fallen out with no suction or whateverness...

So I used one of the ends of a wire rap tie, the really thick long plastic ones that practically can be used as temp replacement handcuff's if the police don't have em oddly. (size example). Anyhoo, used the oversized tip of it to clean all the gunk, and put it in a ziplock to wipe it off so that I didn't touch the durn stuff. (Ugly as heck).

So after all that cleaning, had a pro help me out, and literally use a form of a sponge thing, and some alcohol on it (barely any but enough), it was like a cotton ball but a flat one and he used several together to make it pliable or something. And that thoroughly cleaned the heatsink of the gunk and the cpu.

After all that was done, I kept the heatsink off, removed the pci card's, unplug'd all the fan's, but kept them mounted. (cables out of the way). And literally took the compressed air can, with it's thin long straw approach of directing it. Went outside, and practically nuked the case with it, cleaned every pci port, usb, ps2, around the cpu, in the heatsinks, power plug positions, a helluvalot in the psu, and under the mobo of where it could reach. Dude's, I could have built another cat.... out of the dust... lol...

Anyhoo, after all said and done, re applied some new cpu thermal paste to the cpu, spread it around carefully, put the heatsink on, spread that a bit, took it off to double check spreading it, and applied a little more thermal paste so as to make sure it was covered, but not a crapload of it like it seemed to have happened last time... And it's looking better overall.

After all said and done, I also did the condensed air thinger, or whatever it's called, on the pci video card's, and dude... there was cat hair galore in my old 5200.... surprizingly it still spun fine and dandy. Got 80-90% of that hair out, hehe. (I have 2 cat's, short hair and long haired, hehe).

Anyways, in short, Did a burn in test with literally a program called burn in, and it was a 15min test at 50% cpu and all overall. It "passed", and i'll be adding increments of cpu useage to 70-80-90-100% in multiple tests over time.

The fact it's running so far without any hiccup's is a plus. I can't say it's perfect at the moment, so i'm going to give it a few day's overtime in having it running to make sure that the thermal paste is well prepared, plus the cpu passes it's overall "long" run test.

Thanks for all the help guys, and hey. Here's the pic's of the gunk.... O_O.

Next time you remove the heat sink to check if the thermal paste actualy set right, clean the old stuff off before you put some more on.
