Reinstalled windows 7; Now softwares won't run properly.

Hi, I'm having Windows 7 problems. I did a fresh Reinstall last week, now the software i used to play won't work properly. There are no hardware problems, whatsoever (I keep check ups on my laptop.) I have all my drivers that I need. Let's say, I want to play minecraft! I goto login, it logs ins, but after it logins it's a black screen. (Can't be my graphics card itself, hence i can play tf2. Then again, I might need to see if i have Opengl.) I tried installing let's say, Java clients those won't load or Everytime i try to play everquest on steam it crashes. When i try to install software sometimes it just won't do anything when i click run, they won't do anything further.

Can someone do a team viewer and help me fix?

Btw, I'm Using Windows 64-bit.

are you sure your graphics card driver is installed correctly? windows 7 often installs a GPU which looks to be working fine, until you start a game.... look on the site of your vendors GPU for an updated driver
