I got the DSOD!!

[wingzero]

I got DSOD and Bright Screen Of Death(BSOD). Here's what happened. Today I installed three programs; Pocket Universe, Wisbar, and Battery Pack Pro. Everything works fine after all the installations and few hours later I noticed the ppc is slowing down and then it freeze. So I did a soft reset and it was ok but slow. I then turned it off and then turn it on..I got DSOD. I had to do a soft reset to bring the screen back. At this time, I uninstalled Pocket Universe. Did a soft reset and it worked but also slow. So I turned it off and on again but this time I got BSOD. This bright screen just freeze there unless I hit the soft reset. I wanted to know had anybody encountered this problem with any of these three programs? Any suggestions would be helpful.
