Reboot without warning

Post by PlastiCup »

OKay, currently have a problem. Will be running my computer with some intense computing (converting video to dvd format, browsing the web, downloading a video from a website, moving files on my hard drives, all at the same time when on a sudden click the computer will completely reboot itself. I don't get a blue screen. I don't get any warnings. It simply shuts down and reboots.

This sounds to me like a hardware problem. I don't know which area though. I ran a memory test (memtest86+ i think) and it passed the whole thing 15 times in a row, so i don't think its the ram. Not sure how to test anything else.

I have a 3.0ghz quad core amd processor. 4 gigs of ram (2 sticks). 3 hard drives (1.5TER WD, 1TER Hitachi, 500gig Seagate). integrated graphics. one internal cd drive. All parts are less than 1 year old. The 1 terabyte is the oldest at just near a year.

Thoughts?

Could also be:
Hard drive beginning to fail
Overheating CPU
Incompatible RAM
Failing or inadequate power supply
Failing motherboard

Try reseating all devices
Is this a pre-built computer, or a custom built or home built?

Have a look at the "Automatically Reboot on System Failure" setting. System Properties > Advanced tab > Startup and recovery. If it's checked, un-check it. That may get you an error message and or blue screen instead of a re-boot. It should give you something to look up on Google or post here to help nail down the problem.

Check the Cd that came with the motherboard, it may have a utility to let you check the temps while windows is running. My Asus came with a program called cool and quiet. I used to use a program called motherboard monitor to do it but I haven't done it in quit a while so I don't know if that program is current or not. You should be able to check some temperatures in the BIOS but it won't be under much load. To test RAM you can use memetest. If you want to test your hard drive check the manufacturers web site for utilities.

I did uncheck the box, and now the system freezes completely. I notice that my lights on the mouse and keyboard completely go off when this happens. Lately it has happened while watching videos.

Ok, so i found a hardware monitor for my mobo. it says my cpu temp is 90degrees celcius. something tells me that's hot, including the hardware monitor. i'm running the stock fan that came with it. it's a amd phenom II x4 3ghz. suggestions? contact amd?

I have an AMD Athlon II x4 2.6GHz and it runs around 30c. I would expect the Phenom to run a little hotter but not 90c. What is your CPU fan speed? It shouldn't fail after one year but **** happens sometimes, so have a good look to see if the CPU heat sink is on correctly and not clogged up with dust. Also make sure the fan is spinning OK and not hitting any cables. If you are overclocking go back to stock speeds. Has your case got good air circulation, intake and exhaust fans?

wow... pull the heat sink/fan off and put a new bead of cooling solution on the chip.. just clean both sides off good with rubbing alcohol and drop a bead on it the size of a BB right in the middle and then press the heatsink/fan down on it and lock her down. Then run it for 10mins or so and test the temps again.

If you don't have any solution to apply you can grab some from newegg within a few days.. I prefer arctic silver

for 12$ its well worth it!

So, i'm thinking the program (HWmonitor) isn't reading right, cause I check the bios and it reports a temperature of around 30C, much better. No dust in the fan, the grease is checked and good. I have heard good on artic silver. No overclocking, does not appear to be hitting any cables. two fans running on the case with a third open slot. The same program (hwmonitor) reports my system temp as around 30C. But yet the cpu as 90C. I'm betting the bios one is more accurate. In which case, i'm stuck again as to what is causing it to reboot. thoughts?

Keep in mind the BIOS temp is at idle with no load on the processor. The actual running temp will be higher once windows loads and you start running programs. Still jumping from 30 to 90 isn't normal and I think I would also suspect that the HWmonitor is displaying an incorrect temp. Just make sure HWmonitor is in Celsius and not Fahrenheit. 30c would be about 86f. Somebody here can probably recommend another program to try it you want. I usually just use what comes bundled with my motherboard. It's locking up under load so I guess my next step would be to look at the video card. Kind of the same deal hear. Make sure it isn't clogged up with dust and that the fan is working OK. Some video cards have temp sensors in them like your mother board and if you have the right program you can monitor those too. Some hard drives have them too. One thing that I do when I am faced with a problem like this is to re-seat everything that I can. Video card, RAM, and any other add in cards like sound etc. Then double check all your cables to make sure something didn't work it self loose while you had your hands in there.

I have integrated video, so it shouldn't be that. I checked the temps with cpuid's hardware monitor. the core temps all say 38C. Only something called TMPIN0 is reading 90C, and yes it is C cause it says 192F in parenthesis. Any idea what TMPIN0 is? All fans and hard drives are dust free.

TMPIN0 is likely just a designator (name) given to that temperature function. If its set (assigned) to a sensor that doesn't actually exist on your motherboard you will get a bogus reading. It sounds like your temps are actually OK. The problem with lockups is they tend to make things worse the more they happen. You probably have some file system errors and or messed up files. Might want to check your OS for errors. If you right click your hard rive Icon and open the properties you can check for errors under the tools tab. If it's your main system disk it will likely ask you to reboot for it to work. If you remove the check mark for automatically repair any errors it should run without a re-boot. It won't fix anything but it will tell you if there are any errors and then you can move on from there.

Well, i have tried it under both xp and windows 7, and it does it in both. I'll give the hard drive thing a check though.

I've had some luck taking out one stick of ram. So, either it's a bad stick, or the dual channel is broke, or the slots are bad. I have to do some more testing to find out. Thought i'd share this tho.

if its not a heat issue, what PSU are you running with that setup?

you need to run this program to check your memory for errors...

Antec 650 Tru Trio. Already ran mem test, didn't find any errors, which is weird.

fixed the temp reporting issue. found a beta version of my bios and that fixed it. now testing the stability of it. wish me luck!

No luck. still crashing with two. even worse, it now crashes with one. I now suspect the mobo to be going bad. any other thoughts?

I have RMA'd both the motherboard and the ram in an attempt to fix the whole problem. we'll see what happens in about a week.
