I just updated the ATI Radeon 9600 drivers, I updated the MSI Motherboard drivers, and I checked all of the games that I am having trouble with for updates and I have installed everything. The thing is, it still won't work.

I'm not a techie like you guys, so I don't know what "stock speed" is. And my monitor is a 19" ProView monitor that I got off of newegg.com in November. The resolution of the games varies. I think MW3 is 640x480, Zoombinis is 800x600, Croc2 is 800x600, and LEGO Racer 2 is 800x600 - but I can't be sure of all of those because they obviously won't work for me. Also, when I get to certain points of certain levels in Lemmings Revolution (800x600) it crashes to a black screen and then the desktop as well. This is getting REALLY ANNOYING! *bangs head off of wall* Back to trying to fiddle with stuff...
