Solved Laptop randomly freezes

[Subiray]

Searched a bit on the forums but I am unable to find a solution tied to my situation, perhaps I'm not confident enough to think so at least. So I'll ask for help here.

Lately (past two weeks) my laptop has been starting to freeze occasionally, whenever this happends is seemingly completely random. I'll list what I've noticed:

* Never happended while a game is running (so far), this has only happened when I'm browsing files or the internet.
* Sound goes completely quiet, no repeating or similar.
* Keyboard stops working, caps lock does not show a light.
* Ctrl+alt+del does nothing, screen remains frozen.
* Only option is to perform a hard reboot through the power button.
* No error report is shown when looking at the event viewer.

I have tried to let the laptop shut down/acquire a bluescreen by itself when the freeze happends, after two hours I've realized it's not going to happen.

So I'm just a newbie asking for directions in a dummy-friendly language. What could the reason be and how do I handle it?

Thanks!

The first thing you could try is the System Restore. If you are not familiar with how to do that, there is a tutorial here http://www.sevenforums.com/tutorials/700-system-restore.html Go to a date before you had the problem. This will put your PC in the exact state as of that date.

The system restore does only shows one restore point - 26/12/2013 (two days ago). There are no other available restore points and I have checked the option to show other restore points.

I could still do the restore but it won't help me in any way.

 

[bigmck]

Right, the Restore won't help. == I was thinking that the PC might be overheating. Download HWMonitor CPUID - System & hardware benchmark, monitoring, reporting and monitor the temp. If it gets hot you should get a warning. The CPU is what you are concerned with. The first one is your motherboard and the second one is your CPU. It will have the name listed. If your temps are in the 40 degree Centigrade, that is good. If it gets in the 60 degree area, that is warm. It will probably take something in the 80's to shut it down like the problem you have been having. See how that goes and let us know.

I downloaded it and ran Skyrim for around 30 minutes. I was fortunate enough to have the interface open when the computer crashed after I was done playing, but I was unable to take a screenshot before it happened.

Temp peaked at ~75 degrees during the time I was playing, at the point where the crash occurred the temperature was ~65-68 degrees, which was after I had stopped playing.

I've taken a screenshot after the reboot. I personally can't see anything that's remarkably weird, but I could very well be wrong. What troubles me is that if this is an overheating problem I am sure I would of experienced that when I was in fact using programs that were consuming alot of resources, rather than simply doing nothing.

Edit: Tabbed out to take a look, temp ~70 degrees, peaked at 80 at some point. No crashes ever happened while a game was running (not sure if that matters at all).

 

[bigmck]

It is running hot. That is the reason for the crashes. It will eventually ruin the CPU and other things if it is too hot. In the second screenshot the four cores are all high 70's low 80's. That is too hot. They should be in 40's and maybe 50's for safe running temps. In the hardware you downloaded, I don't see anything about "Fans". Using the same program, mine shows "Fans". It makes me wonder if they are working. Download Speccy - System Information - Free Download "Speccy". Under CPU there should be be a "Fan Speed" listing. See what your RPM's are. Mine is in the area of 1300. Hopefully yours is also.

I concur with bigmck; this is definitely a overheating issue. When was the last time you dusted out the inside of your case? If it hasnt been lately; i would turn the system off and do a complete cleaning of the fans and other components; as dust and dirt can act as a blanket to trap heat in; especially if there is a lot of it. And yea; if yours fan(s) arent spinning at high enough rpm's; it may not cool enough or properly.

Hmm..

Is there a good info-section regarding cleaning the components of a laptop? For some reason I feel alot more insecure when it comes to laptops rather than desktops, especially when it comes to opening it up.

Good idea Matts. == Subiray, you need to check for dust inside. Turn off the power of the laptop and turn it over. It is a good idea to remove your battery before opening the cover. There are a couple sections on the bottom. The biggest one is what you want to remove. Take the screws out and it should just slide off. If you have some compressed air, just blow all of the dust out, especially around the fans. If you have no compressed air, just do the best you can to get the dust out. Maybe a little blowing thru the mouth. Put the cover on, tighten the screws and put the battery on. Power up and see what you have as far as temps and let us know.

 

[bigmck]

No fan speed I see. Mine is below "Bus Speed". Clean out the inside and see if that helps.

 

[Subiray]

I'll do this monentarily. Would you recommend letting the laptop cool off to room-temperature or is it just me being paranoid?

No need to wait.

 

[Subiray]

I am guessing this the section I am pointing at is the one I want to remove. Bear with me please, I'm well aware that I'm making this harder than it already is ^_^

 

[bigmck]

No problem. Glad to help and wait. Yes, open and clean the section you are pointing at

 

[Subiray]

Are you sure that I am supposed to dismantle the large section? I'm getting the feeling that it's not the way to go, then again I could be wrong. Am I supposed to open it through the keyboard section by any chance?

Edit: Did some research on my own, appearently I need to remove the keyboard in order to acess a few other screws.

I have never taken apart a laptop, but judging from the manual you provided, I don't think I would try that either. It appears a bit much for cleaning. Maybe someone else will come and lend some additional info. == I did notice one thing. In the picture you provided in message #13, the air hole in the middle of the laptop appears to have some dirt showing. If it is, you do need to clean it. If that is not dirt, then I would not be so alarmed. Hang in here for some one else who has taken one apart before. Guys check in all time on the problems.

 

[Subiray]

Yeah I figured, I'll keep an eye on the forums for some advice. Thanks for helping me locate what's wrong with it though! Also, I took a peek at what you described but I found no dust or dirt of any kind in the vent. Would you think it's a bad thing to take some compressed air and blow through the air holes? Obviously by no extreme amounts as the fan could be damaged.

If there is dust inside, there is no way for it to escape with the cover on, so it would not do much good. Hopefully someone else will come on that has taken one apart before. I will see if I can find someone online that might lend a hand.

Laptops usally dont show any fan speeds, Their biose's are extremely closed ( i know i had a latop for a long time)

I Would first tell you to clean your computer from dust and blame overheating. But though you said the freezing never happened when yyou gamed ony when searching the internet etc it cant be any heat problems, Try (may help/ may not but it doesent hurt) Rightclick CMD (Command prompt) take run as administrator (Kör som administratör) And type in sfc /scannow
Then when it says its done take (Skärmklippsverktyget) And take a "picture" of what it says and post it here,

And the other thing, What Operationg system are you running. 32/64 bit Vista/7/8 ?

And also Download CCLEANER and scan the computer and also scan for Regristry errors,

Also Run a full system scan with your anti virus system, (would also like to see wich anti virus you use
