Something's wrong...

Hi,
I am new here
Anyways, somethings weird happened to my computer =[ and since its happening to everything i decided to post here
Sorry that i am new here, i dont know the procedures and stuff but heres my problem.
First of all, recently (about 3 hours to now) the programs on my computer tend to crash a lot. I have noticed that some crashes occur when i try to join a chat channel or room. There are other crashes when its loading or just random crashes that pop out of nowhere. Also everything starting to lag horribly. I have restarted my computer but nothings happened.
Programs that crashed:

• Firefox
• Garena (not responding but didnt close )
• Msn (same with garena)
• Heroes of Newerth ( crash whenever i tried to made a new chat channel )
• Steam ( when i try to join a chat room with friends crashes)
• Modern Warfare 2 ( i am guessing if steam crashes so does mw2 but i am not sure)
• Counter Strike Source ( crash during loading)
• and some more i cant remember.

Please note that most of these softwares never crashed before

THANKS FOR ANY HELP!!!

If it began 3 hours ago try restoring your sytem to a time prior to that and see what happens.

Its not a bsod. Windows 7 doesnt freeze. The programs just lag and then crash after doing something. its been happening on almost everything.
