Computer freezes up at random

[shockwun]

Hello, I have been having this problem since yesterday, my computer will Freeze up at random times.
I have windows

Specs:
2.0 GHZ (intel core duo Processor T6400)
9600M GT Nvidia
4gb Ram
320 GB HDD

It happened when I tried to close Skype yesterday, after that I have been having trouble with my computer.
For some reason, it wont let me run programs and when I try to, my explorer.exe crashes.
When I try to open steam, my whole computer freezes and im forced to hard restart.
I tried running the program to see my drivers, but it just would not open.
Can someone please help me?

I uploaded my system information. And I found out that I CAN run programs in safe mode ONLY.
