Computer crashes while playing on Facebook

OK. I just burned the file to a cd and will test my pc overnight. Thanks.

BTW - I had a hard time starting my pc today. had to restart it twice before windows loaded. the first 2 times I could hear the pc turning on, but windows didn't load.

There was no display, so I can't tell if windows loaded or not. I'll update when I get the results of the memtest. Thanks again.

Most of these involve working with fonts. Because they're specific to Firefox and flash, you may wanna scrutinize over your add-ons for Firefox and possible disable all of them, test stability, then slowly turn each one back on. Also, uninstall and reinstall Adobe Flash for your system, using the latest available version (don't forget to update Firefox, too!).

I'm a little concerned because often when corruption occurs with font operations like these, it's because of a rootkit or some other malware that hijacked the font cache driver (this driver is a common target). You may wanna run some rootkit check (like with Kaspersky's TDSSKiller) and through the usual operations for dealing with malware (check the security subforum here). Do not let any scans fix the problems for you. Rather, run them to find if there is an infection, then post the details on the security subforum on this site, linking to this thread for reference.

Thank you everyone.

I ran the memtest and it failed.

I then removed 1 of the memory sticks and the test passed twice (when I placed the stick in different slots).

When I placed the other stick in the pc, I could hear the pc working but there was no display.

Since then the pc is working with the good memory stick and I had no crash yet (it's been like that for 3 days).

So I guess the problem was the bed memory stick.

No. Thank YOU.
