Could be a problem with device drivers, hardware or software . This problem can be solved by uninstalling new softwares, updating device drivers and making minor configuration changes . From http://fixit.in/bluescreenofdeath.html
Norton. it can be used on three computers.

these are the feature's:

full backup of WHOLE hard drive

registry cleaner

live virus and spy-ware update

virus and spy ware scanner

firewall

identity theft protection(for shopping and untrusted websites)

pop up blocker

add on blocker

optimize disk

FREE on line support that's like msn (talk live to agent to help with problems

say you buy all in one security version 1 you can update to version 2 for free

1 year protection

filters downloads for virus and removes them

network cleaner

temporary cleaner(crap files that can store up to 10GB of crap) that's right 10GB

this is what i recommend. things like kasperky arent from trusted websites and i dont think you have support for it

be protected from virus and have your computer at peak performance with norton!! PS. NO JOKE
Can your video card or CPU handle the graphics? Are you getting the blue screen when you try to run those programs?
