Hi all,

I'm having a major issue with my Dell Inspiron 6400 laptop freezing approximately 20 minutes after start up.

I've read through forums and run tests, malware software, ati-virus etc as per suggested solutions and can't seem to resolve it.

Things I've tried:
  • Restart in Safe Mode with Networking - Freezes
  • Restart in Safe Mode - Works! Does not freeze but not very functional
  • Booting into Diagnostics to test over heating - Passes and does not freeze
  • Opened up the laptop case to get rid of dust build up - Still freezes
  • Installed Super-Antispyware - If it reaches the end it will still freeze at some stage - tracking cookies found on each scan and removed
  • Antivirus AVG free edition - Finds nothing
  • Restored it to an earlier time which worked for a day or two but soon went back to freezing...

There is plenty of memory available. I'm now at a loss and don't know what else to try.

I have over the years (I've had this laptop since 2007/8) formatted it several times with a variety of operating systems: Windows XP, Linux of two varieties and finally Windows 7 (current).

Can anyone suggest anything else?

Apart from formatting it again or throwing it out a window, is there any salvation? I really cannot afford a new laptop.

Have you installed the chipset drivers ?

Download the diagnoistic for the hard drive from the manafacturers website and run it. It could be a bad sector causing it to freeze.

Since Safe Mode with Networking freezes but no Networking doesn't, you could uninstall the wireless and wired networking drivers and retest in normal mode.

Also, some basic hardware tests might be in order.

Use MemTest86+ to test your memory for failure.

  • Download the latest version of the Pre-Compiled Bootable ISO (.zip).
  • Locate the file you downloaded, right-click it and select Extract All. Check the box for Show extracted files when complete. Click Extract.
  • Burn the ISO file to a CD. Follow these instructions if this is new to you.
  • Boot the affected computer from the CD.
    • Repeatedly pressing F9 or F12 right after the computer is turned on is the most common way to bring up the 'boot device' menu. Choose the CD/DVD option and press Enter.
  • Memtest86+ will begin testing automatically and is designed to repeat its tests continuously. It is recommended that you allow the program to complete at least 7 'passes' before declaring the memory error-free.
    • Note: These tests can be very lengthy, often lasting many hours.
  • If Memtest finds an error, it will list it in red. There is no need to continue that test if an error is found. You may either press Esc to reboot or you may simply turn the computer off.
  • If there are errors and you are comfortable working inside the computer, begin narrowing down the error result by removing every stick of RAM except for the one closest to the CPU. Begin step #4 again. After the test, shut the computer down, remove the RAM stick, put the next one in its place, and retest. Repeat this pattern for each RAM stick.
  • Report your findings in your next reply.


Perform diagnostics on your hard drive.

  • If you can log into Windows or already know your hard drive's manufacturer:

    • Click the Start Orb and type in "device manager." In the search results, double-click device manager.
    • Double-click Disk Drives. The first drive listed is most likely the one you want to test.
    • Take note of its manufacturer (Samsung, Western Digital (WD), Seagate (ST), Toshiba, Hitachi, etc.)
    • If are still uncertain about your hard drive's manufacturer, include what you see there in your next reply and await further instructions.
  • Use this thread to download the appropriate diagnostic tool.
    • If you are unsure what to download or how to proceed, use SeaTools for Windows. Carefully read and follow the procedure given on that page.
  • If you cannot log into Windows & do not know your hard drive's manufacturer:

    • If you haven't already, include your computer's manufacturer and model number in your next reply.
    • Use SeaTools for DOS. Carefully read and follow the procedure given on that page.
  • Whatever program you use, direct it to perform a 'short-test'. If it passes, perform a 'long-test'. This will likely take a few hours.
  • Report the results in your next reply.

If it looks like I know what I'm doing, there's a pretty good chance the only reason for that is because
I once asked someone to run chkdsk /r and a BC Advisor smacked me in the back of the head.
