Welcome, salar1976, let's see what we can do for you.
It looks like you are having some problems with drivers
behaving like they should.
The first things I would try doing is running "chkdsk /R" in a command prompt, getting a copy of Memtest86+ at Memtest86+ - Advanced Memory Diagnostic Tool
and running that for 5-10 passes, as well as updating all of your drivers [this includes video, lan, wireless, chipset, sound] to their latest stable versions from their respective web sites [not your computer manufacturer's web site].
Let me know how things go for you.
