K^2 Posted August 6, 2007 Share Posted August 6, 2007 I was looking around in the nTune software today, after I had been doing some very intensive encoding, and I realized that my chipset temperature was in the low 60's. This seems very high to me, and I was wondering if both boards could have chipset issues. It shut off three times when I was looking around, and the last time I checked it was at 65. Is this the problem? 60-65C is fine. You don't need to worry about it seriously until it starts pushing 90. But as I said, if the auto-shutoff system is faulty, it can get tripped by an arbitrary temperature. Prior to filing a bug against any of my code, please consider this response to common concerns.

Spenc938 Posted August 6, 2007 Author Share Posted August 6, 2007 It just shut off when I started typing this. I turned it back on, and checked the event log, it was only at 57. Link to comment Share on other sites More sharing options...
Star-Lord Posted August 7, 2007 Share Posted August 7, 2007 Remove your side panel and look inside the computer make sure the fan on the heatsink is spinning. If so when your computer turns off ground yourself and touch the area where the CPU resides if it's hot to the touch then you have an overheating problem. You can tried using an other Heatsink for that CPU with some high quality thermal paste and see if it works for you. On a other note you mentioned that you updated your BIOS, was your computer running fine before this update? Did you reset your BIOS back to defaults and did you clear the CMOS, very important after an update. What was this BIOS update for? Are there any cables blocking the front of the PS Unit? Check the motherboard for leaking capacitors. Good Luck! Hope you solve it soon! I sure would like to know. Link to comment Share on other sites More sharing options...
Spenc938 Posted August 7, 2007 Author Share Posted August 7, 2007 (edited) Both the chipset and the CPU fan are spinning fine. The CPU cooler was replaced at the same time I put the replacement motherboard in so they are both fine. Both of them were applied with AS5. They are also pretty cool to the touch. It also shuts off at random temperatures, sometimes just a couple minutes after I turn it on. I updated the BIOS on the first one after it was giving me problems. I have not yet updated the BIOS on the replacement, because to be honest I didn't see the need. It didn't work the first time. All the cables are routed out of the way of fans, vents, etc. The motherboard has already been replaced, and neither of them had noticeable bad capacitors. Note: Right now it has been running for about 6 hours with all unnecessary components unplugged. I will run it for at least 3 days straight, then if it still hasn't shut off I will start plugging things back in one by one.

K^2 Posted August 7, 2007 Share Posted August 7, 2007 It just shut off when I started typing this. I turned it back on, and checked the event log, it was only at 57. Seriously, it's almost certainly a CPU. Disconnect everything but RAM and CD-ROM. Run Ubuntu. If it still shuts off, you know it's CPU. Bite the bullet and buy a new one.

K^2 Posted August 7, 2007 Share Posted August 7, 2007 Just keep in mind that a short in HDD or (less likely) Ram can still do it. So it's a good idea to try running it with no HDD. You can't run it with no RAM, but if you have two sticks, try one stick at a time, or borrow RAM from another machine.

Spenc938 Posted August 7, 2007 Author Share Posted August 7, 2007 (edited) I ran it with no floppy, cd drive, wireless adapter, sound card, card reader, and extra hard drive for 10 hours and it was fine. Plugged everything back in, and it was off within 10 minutes. That pretty much eliminates CPU, RAM, and my Windows hard drive. Now begins the process of elimination. Edit: The second hard drive was the problem. I knew I shouldn't have taken a Maxtor. Thank you everybody for your help.

Spenc938 Posted August 9, 2007 Author Share Posted August 9, 2007 It just shut off again. It has been running nonstop since I pulled that hard drive. If the CPU is the problem, why did removing the hard drive make it work for so long? Sorry about the double post, but I wanted to make sure the topic got bumped.

K^2 Posted August 9, 2007 Share Posted August 9, 2007 Hmm... If you are convinced that it couldn't have stayed on longer simply by chance, this is getting odd. Normally, I'd blame the IDE controller on such behavior, but since you tried replacing the mobo... The only way I can think of the HDD affecting anything is by being an extra site of power consumption. Maybe if there is a short somewhere, it contributes somehow. Do you have anything to check how much current is drawn from the PSU? Can you run some other configuration. Particularly helpful might be trying to run a different HDD in the place of the one you took out. If it shuts off often in that configuration as well, I'd seek for something related either to power consumption or that IDE chanel.

Spenc938 Posted August 9, 2007 Author Share Posted August 9, 2007 (edited) I really don't know if it was just chance, but I doubt it. When I first thought it was the hard drive I took it out, put it in, and took it out again a couple times. When it was in, it shut off almost immediately. When it was out it was fine. Plus the motherboard and power supply have been replaced, and the CPU and memory have been tested extensively. (I know this doesn't completely eliminate them, but pretty close.) I think a friend of mine has a multimeter, but I have no idea how to check a power supply. Edit: Now that I have reread your post, I don't think that is what you meant anyway. The drive I removed was SATA, I don't have another SATA drive I could replace it with though. My power supply has an additional 4-pin connector built into it that I don't have plugged in, but I thought it was just for when the system was being used in SLI. Maybe I should try plugging that in... I am not going to do it unless you think that could be it, because getting a molex down there would be a huge pain in the ass.

Primer43 Posted August 9, 2007 Share Posted August 9, 2007 If your talking about the molex connection way down on the bottom of that mb, don't bother powering it, you were correct in saying it is only for sli. Link to comment Share on other sites More sharing options...
Spenc938 Posted August 9, 2007 Author Share Posted August 9, 2007 I thought it was. I'm just trying to think of everything. Link to comment Share on other sites More sharing options...
K^2 Posted August 9, 2007 Share Posted August 9, 2007 Here is a thought. Have you tried plugging a different PC into the same outlet? It would be sad if all your troubles are caused by the power fluctuations. You wouldn't be able to test power consumption with a multimeter, because there are multiple outputs from the PSU. There are devices you can put between PSU and outlet that will monitor power consumption over time. If your PSU is good, that should be good indication of how much power is consumed by your PC. One last possibility I can think of is a short in HDD frying something on the mobo, resulting in shut offs even when the HDD is removed. The problem is that I have no idea how to go about testing this without frying another mobo. Prior to filing a bug against any of my code, please consider this response to common concerns.

Spenc938 Posted August 9, 2007 Author Share Posted August 9, 2007 I haven't tried another PC in this outlet, but I have tried this PC in another outlet, and it still did it. I never did have time to switch surge protectors, maybe I'll do that right now. With the amount of stuff that we have checked, I am seriously thinking that it could be either the surge protector, or the power in this room in general. I am leaving for a week and a half next friday, maybe I'll put it in another room then and see if it will stay on. But I will still try the surge protector today.

Spenc938 Posted August 13, 2007 Author Share Posted August 13, 2007 I just tried to load an overclocked profile from Ntune, and it killed right when I hit the button. I guess I just proved myself wrong, it is the CPU. Link to comment Share on other sites More sharing options...
K^2 Posted August 13, 2007 Share Posted August 13, 2007 Try underclocking your CPU, then. Maybe you ended up with a lower clock CPU that accidentally got rated higher.

Spenc938 Posted August 13, 2007 Author Share Posted August 13, 2007 Stock, it is at what it is supposed to be. I'm still thinking in the back of my mind that it could be a problem with the incoming power. Whether with this room, or with the surge protector. I never did switch it, because the other one is in use behind a 55" television, and it is kind of hard to get to. Link to comment Share on other sites More sharing options...
