Icons and such disappearing... o.o

If your icons are loading at a slow rate, it is because playing MS uses a lot of memory, if you didn't know. However, I haven't experienced my icons blackening-out.. on my PC or on my Laptop. My PC has 1GB of RAM, my laptop has about.. 2GB. If it stays blackened, I can't say much there, because I wouldn't know the solution to that. If I told you to get more RAM, I'd just sound like a idiot, because I could be wrong, and that's not always the solution. -shifty eyes-

I have 2g of ram...
