How do I figure out what's causing my computer to freeze and restart?

KoreaJPG · 26 Aug 2015

This issue came up a few days ago, I was just surfing the web and talking to friends on teamspeak when suddenly my computer froze, then it seemed to turn off. However, several seconds later it booted back up. This started happening more and more frequently and now it happens a few minutes after I turn on the computer.

I don't know what's causing this to happen and I would greatly appreciate any help in diagnosing the problem, as well as trying to fix it.

I'm not very knowledgable about computers and so if you guys can explain the lingo to me as well that would be helpful.

EDIT: I'm posting this on my laptop but most of my work is on the computer and I need to fix it asap.

From what you describe it could well be a temperature issue.
Are you seeing a BSOD when the machine is crashing ?
Is it actually shutting down or is it hard crashing as if the power were removed ?
Does the machine reboot afterwards ok ?

You could try running this and uploading the log files may give us a bit more info to work with including any dump files if any were created

When it crashes, my monitor turns off and then it just restarts normally except it said that the computer wasn't turned off properly, so I have to select the "run computer normally" option.

When it turns off, the lights on my keyboard go off, but the light on the power button remains.

I do not get BSOD at all.

Hi and welcome to SevenForums,
Try selecting safe mode with networking to see if it crashes again.

If it doesn't use clean boot,
Could be a virus or driver issue....
Troubleshoot Application Conflicts by Performing a Clean Startup
Click Start and type in the search box,
msconfig
Click on the suggestion on top or hit the Enter key,
Go to the Startup section and take some screen shots for a complete list,
Go to the Services section and on the bottom left Check the box to Hide All Microsoft services,
Repeat the screen shots,
See the links above my signature on how to take and upload screen shots here,
Cheers.

I have turned on the computer using safe boot + networking and I haven't had a crash so far. My computer seems to be running quite slow though, I don't know if that's because it's in safe mode

This is all the programs that are checked for start-ups, everything else is unticked.
The item "starter module" is a screenshot program called lightshot which I've had ever since I had this pc.

Hi and thanks,
Well I have read Avast will bring a system down to it's knee's :)

Java about the same along with Apple crapware I'd remove both

Not sure what kpeernexo.. is or starter mode ?

Can you also post a programs and features screen shot ?
Switch to List and a lot more listing will appear on the screen

What free anti-virus software would you recommend apart from Avast?

Hi and thanks again
You have quite a boat load of goodies there
Fill in your system spec's with cpu-z or the link above my signature so we can have more info on the machine

Red flag for me is always Utorrent
Where is your favorite download place for all these third party urilities...... ?

Personally I would use Panda but I have Malwarebytes premium so I can use MSE
Which is my next suggestion go into safe mode with networking and download mbam free and scan the entire system,

Then restart using clean boot and uncheck everything on startup except for Avast
Then rescan using again the Custom scan and all connected drives.
Uncheck use the free trail in install options,

Review Jacee’s instructions to run Adwcleaner here post #7,
Ignore the title of the thread,
Instant Savings App
On the BleepingComputer site use the button that looks like this,

Post the scan results.

Okay I have filled in my system specs.

I don't understand your question here "Where is your favorite download place for all these third party utilities"

I'll edit this post once I've finished with the scan

I was told to just post on this thread and update it by a user.

I booted up the computer in safe mode with networking and tried to scan the system with malwarebytes but during the scan my computer turned off by itself, this was the night before I had to leave town for a while.

When I came back, the computer didnt turn off by itself but now I'm getting BSOD sometimes and I don't know what is causing it to happen.

Everything loads super slowly, it takes minutes to load up chrome or anything in fact and even typing on this thread is laggy.

What can I do to fix the super slowness of my computer? And what can I do about the BSOD?
