After getting a Dell person to troubleshoot my problem (even though my warranty is expired), it was determined that my laptop either had a bad graphics card or a motherboard. I tried the graphics card first since it was cheaper. I found a used one online and VOILA...my laptop lives again.
This morning the bus I catch to the metro station didn't arrive. Sometimes it varies by five or maybe ten minutes. The bus goes by every 30 minutes. So I stood there for about 35 minutes when the next bus comes by. Of course, everyone else that was waiting for the bus that didn't show was on this one too and I had to stand. How annoying.
