Wow, that is some collection you have there.
Firstly I recommend you download the w32.Blaster.worm removal tool from here.

There is no removal tool for the W32.Randex.gen so the best thing to do would be to download AVG and update it, then boot into safe mode and run a full system scan from there.

Once you have scanned and hopefully removed the viruses then it would be a good idea to remove all that spyware you have, download and run this program.

The best way to find out about your graphics card would be to run this tool.
