Computer freezes when playing some games

[yakamato]

Hi, I recently found out that my computer freezes when I am playing games that don't need good hardware, like crossfire and need for speed carbon.

When the computer freezes its first the game, then the reset of the computer after half a minute.

I have uploaded Dxdiag as an attachment.

Thank you for any information

There may be an issue with your Realtek HD audio driver. Do you have any yellow exclamation points in the device manager?

 

[yakamato]

thank you for the assistance, but no, there is no exclamation points in device manager.

any other ideas?

by the way,

i can run Call of duty modern warfare 3 and skyrim without the computer freezing.
but older games lag more and freezes the computer.

Try updating the Realtek audio driver...

The problem is, that there is no updated driver for that sound card. no for windows 7

So you installed Windows 7 over another version of Windows?

 

[yakamato]

i installed windows 7 on a newly formatted hard-drive, so no older version on the computer, but the problem was there with some games on windows Xp as well

XP was on this PC first. You may have to add a separate Windows 7 capable Audio card

 

[yakamato]

i have done that, i have added a creative sound card.

and thank you for helping me, much appreciated.

So the games are good now?

 

[yakamato]

no sry, maybe i should have written that^^ they still don't work

 

[yakamato]

I still have this problem, so any ideas?

 

[Tmagic650]

So these problem games didn't play well on XP either? I have no other ideas... Sorry

well i had the problem with overheat before i changed some parts, but after that it was fine, but now when i got to windows 7 and new parts on the pc, some games freezes the computer. especially cross fire and need for speed carbon.
