update video card drivers?

and what power supply are you using?

 

[TheDumbass]

video card drivers and all pc drivers are up to date and i hawe 450w codegen power supply

Just test with a different PSU if possible. Maybe the card is not getting enough power from it.

 

[TheDumbass]

but it did before and problem is in all games and i mean that older game should use less card so card uses less power and it should work but it still freezes
and i disconnected most of stuff from my pc and it still freezed

You haven't dislodged a power fan wire / Broken a RAM slot by leaning on it (or short circuit)?
The memory your using or play the game from is not external / diverted through a raid card?
And the game I play the most ie sit in front of the longest is on my main HD (small 30Gb) faster to access for the CPU. The other games I play still work through the raid but react slower. I actually don't notice it with my eyes, just my fingers never seem to be quite quick enough

no and i am only one how is touching my pc so i am sure nothing isn`t short circuit
and freezeing came when i launched dead space (it worked before) then i tried other games and freezeing started to occour more and more games

First, I love the name you chose. :grinthumb

Second, when you updated drivers did you first use something like Driver Cleaner Pro or Driver Sweeper (they both have free versions that work very welll) to make sure all old drivers were removed first?

 

[TheDumbass]

no i updatet drivers manualy but i will try now
big thank you to Route44 and others how helped it was driver problem like Route44 said
