PC Turns Off Automatically

[reagan87]

Hello friends,

I've been experiencing a very strange problem for sometime and I'm in total confusion as what would have caused this damn problem. The problem is that my PC turns off automatically on its own. Sometimes even after 5 seconds of rebooting the PC, it turns off without any notice or messages. This happends very frequently and its very annoying since I would have to reboot again and again till its stable and continue smoothly maybe for around 10 - 25 minutes until its turns off again. I've checked the CPU temperature and its around 60-65 C and I'm not sure if this would have caused the problem. If there is anyone out there who would have experienced this problem and came up succesfully with a solution, please do advice me on what should I do. Or even an idea would do to help me out. Thanking in advance.

Regards,
Reagan

60-65C is too hot. You need to cool down the processor more. I do not know if that is what's causing your problem, but it is a problem nonetheless. It could also be a bad powersupply.

If that's the case, then what am I supposed to do to keep the temperature all time low?

check your thermal paste or replace cpu cooler could be failing , i m sure there is a failsafe setting on your mobo and/or cpu that when it overheats it shuts down to protect your hardware so check you cpu fan for sure / example i am using stock standard cooling and my cpu runs at about 40degree celsius and that is with a maximum load that i could inflict , 100% cpu usage

Ok, what chip are you running? 60c is too hot for an amd, but is almost normal for a intel, especially the more recent ones. In either case, this wont be your problem given that the stock settings in bios do not turn off your computer until it reaches 100c plus. Having said that if you do have an amd getting some better cooling wouldnt hurt.

What i would do is keep an eye on the voltages coming from your power supply, you may find they are over/undervolting resulting in the computer turning itself off to prevent damage to the components. Also you'll want to check your graphics card's fan, it could be that which is overheating, although if its an older one you probably wont be able to monitor it.

what are you using to get your cpu temps first of all.... Second, open the computer case and take a large fan. Point the fan directly into the computer...does this solve your issue? If not, run the computer again and watch the fans....do any of them stop spinning or behave irradically or anything like that? Did you build this computer yourself or did you buy it pre-built. Also, have you upgraded or added anything to it?

I've just pasted a new thermal compound and replaced the CPU heatsink and the fan with a newer ones. But it seems that the problem still persist. I'm currently running an Intel Pentium 4 chip. And after replacing all this newer items, it also seems to be that the temperature has risen to 68-70 C at the moment. What can I do to keep the temperature all time low? And i am not pretty sure about the Power supply but it has an output power of 400 W.

You can check voltages with everest home or similar, which is free

I know what the problem is ( go here and uncheck the box)

Ok go here

right click My computer
go to Properties
go to Advanced
click on Startup and Recovery click on (Setings) at the buttom of page

in side there you will see System Failure in the middle of page
look for Automatically restart and uncheck it, this should fix the problem

I know I've been there and it really Sux. no one had a clue what I was talking about until I found it on my own

what OS do u have, I have XP, 2000 this is the right steps to fix the problem,

Help this helps

I just biult a new unit that had this problem. Fix: the bios had the primary display adapter set to PCI. The above fix, ( i.e. right click "my computer, startup & recovery, settings...), did not work. CPU temps are normal. Power supply @450w .
All parts are new except CDRom &CDRW. I'm listing this reply to provide anyone else with this problem a possible solution.
It's a damn frustrating one!
