Blue screen of death errors are generally not due to Firefox, but usually your hardware or operating system.

You should try the following:

1. Check that your hard drive is functioning properly and healthy
2. Run a Windows CHKDSK
3. Scan for registry errors (I recommend using the free CCleaner tool)

If that doesn't work, try reinstalling Firefox.

Warning: To prevent data loss, be sure to backup your data BEFORE attempting any of the steps listed above.

Hi Wesley Thanks for taking the time to reply but the problem still occurs. Actually the issue shows up using another browser too. I'm baffled. Gus50310

This means the computer is sick.

Hi FredMcD Thanks for taking the time reply and I followed your suggestions but the problem still occurs. It seems directly related to when I am using Firefox. I have had Firefox as my goto browser for a number of years but until there is a Firefox update to try or a path to get direct support on this issue I am just going to turn off its use. If there are any suggestions or questions please let me know.

I've called the big guys to help you. Good luck.

Thanks FredMcD If it helps any a symptom that occurs and is a sign a crash is likely to be on the way is there will be a weird effect for a sec or so in the audio it that it gets warbled. Gus50310

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen or hold down the Shift key) to see if that has effect.
