I would suggest you to download third party called memtestx86, burn it to CD using , and let it run for at least 7 passes

Please remove any virtual CD program such as Deamon tool or Alcohol 120%, they use sptd.sys, which is known for causing BSOD. Use this tool to remove sptd.sys

Do system file check:
SFC /SCANNOW Command - System File Checker

Your dump files report a couple different problems...

1.Run sfc /scannow command from an elevated command prompt ( in start search type cmd then right click the icon and click "Run as administrator" then scan the whole system files by typing run chkdsk /r to check disk errors. as Tuan stated...

2. Make sure you are up to date with the latest ATI drivers. Perform a clean uninstall of the drivers then boot in safe mode and use driversweeper to clean up the leftovers from ATI. Allow the system to restart and load default vga drivers before installing the latest drivers.

3. Make sure your directx is up to date if not visit the Microsoft directx site and download the latest directx.

dump file?

Was it a Bad_Pool_Header?

and to add:
I have never witnessed a BSOD while doing a check... Was the system idle while checking or were you using the system? Browsing websites with flash? or so on.

one week earlier everything was fine...the whole system worked correctly - that's why I think it's not hardware problem....

How can I reinstall windows 7 ? I tried earlier on another machine... but it seemed to be different from XP... What's the trick ?

Do you mean an in-place installation without losing your information and files?.. but before we jump ahead we still need that dump file.

In-Place installation:
1) Insert the Windows 7 Installation Disc to your DVD-ROM drive. If AutoPlay pops up, click “Run setup.exe” directly.
2) Click “Install now” on the “Install Windows” screen.
3) In the “Get important updates for installation” screen, it is recommended to select the first option to download latest updates for installation, if Internet access is available.
4) Check the box “I accept the license terms” to agree with the installation license and click “Next”.
5) In the “Which type of installation do you want?” screen, click “Upgrade” to perform the In-Place upgrade.
6) Then, follow the wizard to finish the In-place Upgrade process.
