problem. somehow random crashes. CPU problem i think

deem3r · May 1, 2007, 05:53 PM

CPU: Intel D 820
MB: GA-8I945PLGE-RH
RAM: 1 Gb DDR2 533 Mhz
OS: Windows XP with SP2

Hello guys,

I've had some problems with my CPU overheating from the moment i bought it. Initially i solved them by running my fan at 100% (more than 3000 rpm). As time passed i realised, mainly in games that performance decrased as long as i used the CPU at high values. I checked the temperatures and indeed they were very high 75 degrees C.

So i thought to give it a look inside de case, there was a pretty thick layer of dust and debris on the heat sink. I cleaned it, very carefully. After i started my PC again, I checked the temperatures in BIOS, they were normal as well as the fan's RPM, thus i continued to load Windows, after i logged in it crashed. Pretty nasty crash i might say, the screen went blue with vertical lines. I turned it off and after a couple of minutes i started it again. I was able to log in, started my usual programs, reading some news, and after 3-4 minutes it crashed again with the same nasty screen.

If anyone knows something about this kind of behaviour i would appreciate it.

Thanks.

How is your Voltage on the cpu and ram?

i'll include a screen with them, taken from Everest Home Ed.

thermal paste dude? get some good stuff like Arctic Silver 5 http://www.newegg.com/Product/Produc...82E16835100007

If this problem were due to the CPU overheating only, I'm of the impression that the system would shutdown/restart rather than just produce a corrupted screen.

I notice that the 12V voltage is slightly under 12Volts. I'm wondering what kind of PSU you have and what is the AMP rating on the +12V rail? It would be of interest to see how much lower that 12V goes under stress.

Sometime back, I ran into a similar problem. I had gone into the box to change something (CD-DVD drive) I think, and when I got everyting buttoned up, I started getting really odd crashes, and vid corruption. Then it acted like the vid card was dieing. I could boot into safemode but not normally. I got a new card, and still had the same prob. At that point I was thinking PSU, and replaced that. Then I thought maybe it's the RAM, so I ran memtest, and sure enough I got LOTS of errors. I went into the box, and was going to pull one stick and run memtest on just one at a time to isolate the problem, when I found the REAL problem.

It turned out that when I was replacing the CD-DVD I had somehow 'nudged' the RAM just enough that it had been unseated. I pulled, and re-seated the RAM and all errors went away. Since you were just inside the box, it wouldn't hurt to go back in and re-seat your RAM and all of your other cards. It won't take all that long, and may save you a lot of headache, and money. I'm not saying that this IS the problem, but it won't cost anything to try it.

Done this already with the exact thermal paste you linked me. Anyway, temperature is no longer an issue after i cleaned the heatsink.

Had the same problem myself a few years ago, same reason. Now i'm really carefull and check everything after i work inside the case no matter how small is the job i do. Anyway i checked the memory stick, the video card and everything else. They were all in good place. Ran a memtest, and everything was ok.

Yeah, i know, thats why i'm a bit worried.

The 12V voltage, under stress(gaming/benchmarking) came as low as 11.71V.
PSU:Enermax Liberty 400W, Model ELT400AWT -->http://www.enermax.com.tw/english/pr...ay1.asp?PrID=7

All in all, i see that the crashing doesnt occur anymore.

Dyre Straits · May 2, 2007, 11:04 AM

You likely are already aware of this, but, when voltages drop below certain levels, it causes the components to struggle more, thus producing more heat.

You haven't mentioned which video card you're using, but many of the newer cards of late are needing as much as 30+ amps on the 12V rail. It just may be that you should be giving some serious consideration to a 500W or better PSU with a single 12V rail with 30A or better.

At any rate, that the crashes have stopped....for now....is good news. But, I wouldn't be too surprised if that reoccurs sooner rather than later.

Good luck!

PCI-E His Ati X1600 Pro 512 Mb 500/400(gpu/mem).
The board has passive cooling, meaning it has no fans or temp sensors.

Yes i know, i'll take in consideration buying a new PSU, something at 600W, and a new cooler for the CPU.

Thanks to everybody.

in one version of the Everest it can read the +12 Volt @ 11.71, while in another version... or a different version of the Everest, like its older/newer or updated version, will have 12.xx something. this is possible, and it depends on how the software code (in each version of it) has been written for and how well the software and your hardware/sensors work together. i like to suggest you also find a different ways to check all the voltages...

In BIOS, the voltages (+3.3 and +12) were tagged as OK, though no values were shown.

This screen was taken from SpeedFan. As you can see the voltages have the same readings with those from Everest. (1.97 max, 1.71 min)

PangingJr · May 2, 2007, 12:50 PM

IF your Gigabyte motherboard uses IT8712F as its sensor chip then as i've found that Windows program likes Everest, Speed fan... may have incorrect info on some of the voltages readings, some of the boards's utility programs are also having problem reading out the infos off the boards that using the sensor chip.
on the system/CPU's temps and fans however are sometime correct when compared to the boards utility programs and BIOS.

My mobo is equiped with the chip you're talking about (IT8712F)

PangingJr · May 3, 2007, 10:45 AM

if you have already posted the info then please tell me this below info again...
what is your video card and how many drives in your system??

i would probably not worry about voltages...
only if you want to have an accurate reading of the voltages, then you may want to test your power's voltages with a multimeter.

deem3r · May 3, 2007, 12:21 PM

GPU - Ati X1600 Pro PCI-E 500/400
1 HDD Seagate 160 gb
1 optic drive(dvd-rw).

These are all.

PangingJr · May 3, 2007, 12:58 PM

those and these...

CPU: Intel D 820
MB: GA-8I945PLGE-RH
RAM: 1 Gb DDR2 533 Mhz

the Enermax Liberty 400W should be able to handle a system like yours.

if there is no problem with the processor overheating anymore after you reinstalled the system processor's fanheatsink include its thermal compound, and no more problem with the random crashes, however if you are still worrying about the voltages dropping, then i would stop worry about it if i were you. or otherwise, if possible, perform further test on the power supply's.
