5 times in the last 24 hours my computer has just shut down unexpectedly. It's as if the power is cut to it. Within a second it restarts, and is then fine. No errors, no warnings, no freeze ups. I am running Windows XP and have some ideas, but cannot figure out the problem.

It may be heat related. When was the last time you cleaned out the inside of your case?

Oh it's been a very long time. Not good, but I just don't do it like I should. I'm not even completely sure how to do it.

If you still have the issue after cleaning it, or would rather avoid cleaning it, then please download and run hijackthis Do a scan and then save a log. Take the log and ATTACH IT (do not post) to your next post. In order to attach it, you will either need to change the .log extension to .txt, or you will have to put the log into a compressed (zipped) folder.

We do not like to post hijackthis logs in sections other than the malware forum as we do not want to encourage people to post malware issues in this forum.

I am not looking for malware. I am looking for what programs or combinations of programs might cause this behavior. If I notice any malware, I will redirect you to the malware forum.


Overheating tends to freeze the computer rather than shut it down. Computers with certain sensors and safeguards do shut the computer down when overheating though...so it is definately possible that is the cause.

It was fine last night after I posted and then all morning. Apparently while I wasn't on a little while ago it restarted on it's own again.

Here's my HijackThis log.

There's a few things in there I'd like to get taken care of, but nothing that could cause your symptoms. Let's collect a bit more info before we do anything.

Please download Speed Fan and install it.

Start Speed Fan. When it is fully loaded, take a screen shot of the first screen by pressing Print Screen/SysRq on your keyboard. Open Paint and paste. Save the screenshot as a JPEG and post it in a reply to me. Now click on the tab called S.M.A.R.T.. Select your hard drive by using the drop-down box at the top. Now take a screenshot of that as well. Post it in your reply to me as well.

NOTE: For certain computers, Speed Fan will not display accurate measurements. If the temperature wildly fluctuates or doesn't change at all, let me know, otherwise I will believe the mesurements are accurate.

I downloaded Everest(sorry I couldn't figure out how to get to Speedfan), it has a Motherboard temperature of 48-49 degrees C and the CPU at 55.

there's much more info that Speed Fan gives me than Everest. I wish I could just give you a direct link, but they don't allow that for some reason...

Go to the site, click Download at the top. Look at where it says SpeedFan 4.28 in blue (towards the middle-left). Click on that. That is the dowload link.

Looks like we got a couple of issues here.

1. Overheating This must be addressed or damage could occur I don't think this is your problem, but it could become your problem in the future.

Check all internal fans to make sure they are functioning. Clean out interior with canned air. Make sure the computer is not in an enclosed area, that it does not receive proper ventalation.


2. Hard drive errors The SMART data of your hard drive indicate many Raw Read Errors. Raw read errors mean that the magnetic media inside the drive is no longer capable of reliably storing information in that sector. In many cases, this leads to a cascade of data errors on the drive.

If you value your data, replace the drive now! Odds are this is the entire cause of your problem!


That's why I don't use Everest. It's not as useful as Speed Fan. :whistling:

Alrighty, but get ready to back up all your data. The Raw Read Error problem is a critical issue that will only get worse as time goes on.

Don't wait until it's too late! :whistling:
