My computer turn off for no reason

[Pawelk198604]

I afraid that it maybe some hardware issue because system restore not help. Does is may be processor or GPU?

Does is any program to check does is cpu falaut :-(

Usually, when computers switch off randomly, it's because of thermal protection. Are you fans working properly?

You should get a little program to monitor the CPU temperature.

Use Speccy to monitor temperatures, mainly your CPU and GPU.

If all are in the green, then it's time to look at your PSU. Try your temps first.

i agree with these guys, sounds very much like a CPU temperature issue. most motherboard firmware will shut down your computer for safety if it detects temperatures exceeding 60-65C (varies a little by manufacturer and model). if you're using the stock cooler on your CPU you might want to invest a small amount in a beefier one, most basic aftermarket coolers are way quieter and more effective.

Make sure your existing fan is actually turning fast enough and not caked in dust before spending on a new one

Apart from the mentioned temperature concerns, your PSU might be failing. Try also measuring its power output and see if it is stable.

[cicatrix]

As it's been stated already it's overheating. Disassemble your CPU heat sink, clean the dust from the fan and the heatsink, apply a new fresh layer of thermal grease, re-assemble.

(Don't do it yourself if you don't know what I'm talking about - take it to someone who knows)

Just one step at a time guys, or he could totally wreck the thing, if it's under warranty get the shop to sort it out.

If not, then open it and check the fan, don't remove it, if it's working then make sure air is actually getting into the case.

Let us know what happens and we'll go from there.

There's no mention of the conditions in which it turns off. Aside from the heat issues mentioned above, it could also be that the PC is set to sleep or hibernate if left idle for too long. If that is the case, simply changing the power settings could fix the problem.

On an good case the cpu fan can stop and the chassis fan is able to cool it for some time.

Has seen it many times.

Might even be something as simple as an wire block the fan, not unusual on stock fans.

[cicatrix]

It's dust. Usually.

writing to you from my brand new Galaxy S3 LTE ☺ because I cannot run my PC for longer than 5 minutes! And the modern Ui icon look strange than usual no filing

[Red Iron Crown]

87C is really high for a desktop CPU, definitely looks like a heat-related issue. I'd open the case, clean out any dust that might be blocking fans and the CPU heatsink, and start the PC with the case open to verify the fans are all working.

[cicatrix]

Dry thermal grease can render cooling ineffective:

So, disassembly might still be in order.

Does is any program to check integrity of my GPU and cpu, i mean that it demage

It or not

[sal_vager]

Only stress tests, like 3Dmark.

If it is damaged it'll keep failing, if it's working don't worry about it.

Ps how much i need to spend to buy new Intel core 2 quad Q8400 if they still in market I'm not rich:)

[Pawelk198604]

I wonder does I can repiar win8.1 with win 8 orginal disc?

ps how to swich back again to mobile forum interface?

How to you know the processor is dead? We told you it's either the fan or the power supply. Did you check those?

You don't need to reinstall Windows.

It sounds like you don't know much about computers. Your computer is new, right? Then bring it back to shop and get it fixed under guarantee.

Oh, and if you do remove the CPU fan, DO NOT SWITCH ON THE COMPUTER WITHOUT A CPU FAN. It will fry the CPU in less than a second.

[sal_vager]

It should just complain at the Bios/Eufi that the fan speed is zero and prevent you from going any further, it's a safety feature

Now i use my laptop, now i have tio fogot plaing KSP, Take On Mars and Rome 2, and Europa Universalis because i have only two core, and ! gb ram, and UBUNTU :-(

Reinstalling the OS has nothing to do with your problem with the CPU or fan. You can deal with an OS upgrade when you've fixed the other problem.

If your computer has Windows XP on it, it must be ancient.

2009 but it was one of beter that's time

[Nibb31]

Windows Vista came out in 2007. It must be older than that. No wonder it's shutting down randomly. The power supply might be dying, but it could simply be full of dust and in need of a good cleanup.
