Computer acting weird

Hi,
I wanted to watch a DVD on my computer but I didn't have a DVD decoder. I downloaded a program but it didn't work well so I removed. At the same time I updated my graphics driver. My computer has been acting a little weird since I did this. The screen picture will pulse for a second every now and then. Also, one time it froze with a bright white screen. I scanned using my av software in safe mode and also did the scans from the read-me post.

Thanks for your help. I should know better than to download programs off the internet. :-o
