Hi,

I've posted a few other times in the Malware forums, never before on this form.

Lately I have been experiencing a very troublesome problem.

Often it happens shortly after booting my laptop, but it has also happened hours after.

Things will be operating normally then my desktop and toolbar will completely freeze up and will not recover from this state. If I have a firefox browser open at the time, it is possible for me to continue using it but it eventually will also freeze.

Ctl+Alt+Delete key combo does nothing and I am forced to power down and reboot.

I do frequent malware scans using MBAM, Super-AntiSpyware and have auto-update AVG Anti-Virus. All come back clean, so I'm confident it's not a virus/malware issue.

I just really have no idea where to begin troubleshooting this issue. I can tell you that analysis of the System, and Application event logs show nothing that alarming that could relate to this issue (although I could be looking past something).

Any help you can provide to help me deal with this issue will be greatly apppreciated!

Please, post some computer info:
- processor type, amount of RAM (hold Windows logo key, hit Pause/Break key)
- hard drive size/free space (open "My Computer", right click on hard drive letter, click "Properties")

I would start with heat...and browser add-ons...as primary suspects.

Freezes without error messages...may tend to be instances of system overheating.

Hardware problems may or may not reflect error messages, depends on the nature of such. I'd start with a check of the RAM and the hard drive.

Nothing alarming here....

Run hard drive diagnostics: http://www.tacktech.com/display.cfm?ttid=287 (or http://www.bleepingcomputer.com/forums/ind...ive+diagnostic)
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.

NOTE. If your hard drive is made by Toshiba, unfortunately, you're out of luck, because Toshiba doesn't provide any diagnostic tool.

==============================================================================================

A. If you have more than one RAM module installed, try starting/running computer with one RAM stick at a time.

NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option A

B. If you have only one RAM stick installed...
...run memtest...

1. Download - Pre-Compiled Bootable ISO (.zip)
2. Unzip downloaded memtest86+-....iso.zip file.
3. Inside, you'll find memtest86+-....iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon:

8. Locate memtest86+-....iso file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:

Posted Image

10. Once the CD is created, boot from it, and memtest will automatically start to run.

The running program will look something like this depending on the size and number of ram modules installed:

It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.

The following image is the test results area:

The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.

Hi there,

Sorry for the delayed response I've been away.

I attempted to run a HDD diagnosis using the tool you suggested but it does not seem to recognize my Fujitsu HDD, even though I selected the Fujitsu option.

It suggests that maybe the Master/Slave setting is correct or that it's not plugged in correctly.

Should I proceed with the rest of your instructions?

Thanks

What is the exact message, you're getting?

You can proceed with RAM testing. Those test don't have to be run in any particular order.

OK - I'll proceed with the other tests.

I'll post the message when I respond with the results of the ram tests.
