Applications hang and system freezes

[luvshines]

I am running Ubuntu 10.10 on a Lenovo Thinkpad T61p with 2GB RAM.
When I was on Ubuntu 10.04, one day suddenly Azureus hung at the 'loading plugin' screen as it begins. I had to hard reboot my system and it(Azureus) never worked after that so I removed it.
Then after a couple of months same thing happened with Adobe Acrobat reader. As soon as I opened any pdf and started to scroll, it hung. System didn't respond and had to hard reboot. I moved to foxit reader

Then I upgraded to 10.10 and now mplayer hangs occasionally if I try to switch it to full screen. System stops responding totally

Any ideaz/suggestions ?
Where to begin debugging from ?
I can't figure out any pattern or any way to reproduce it.

I haven't tried Acrobat reader and Azureus on 10.10

what is the graphics card for that computer?

Are you using any proprietary graphics driver? If so, what - and how did you install it?

This is what it says for graphics card

lspci  | grep -i "vga\|display"
01:00.0 VGA compatible controller: nVidia Corporation G84M [Quadro FX 570M] (rev a1)

I installed the drivers from System --> Administration --> Additional drivers, the one which was recommended

its time to look at errors logged, that can help

Ok, but do Adobe reader or mplayer log error messages to some file or produce any core dump for analysis ?
Since the system hangs completely, the only way to look into the error logs is after a hard reboot

into /home:
.xsession-errors
.adobe
.mplayer
& so on

into /var/log/ (system admin logviewer)

Not facing these issues now. Didn't do anything special, just regular upgrades.
