BSOD after boot, but only during first 3 min!

S!

I have a problem with my ATI HD4850/Windows 7 32bit retail. After system boot, I can not do anything for the first 2-3 min (i.e. open programs), otherwise BSOD comes out. If I wait for 2-3min, the PC works fine, and I can re-boot the system without problem: the BSOD appears again if the system was off for long time (i.e. 30 min).

I have changed two monitors (a VGA and a DVI), with Catalyst installed or without it... same problem.

Any suggestion?
Thank you.

Please navigate to c:/windows/minidump, zip up any .dmp files and attach them to your next post.. None were contained in the last attachment..

Your .dmp file shows a 0x124 hardware error.. Unfortunatly it does not really tell us a lot about which piece of hardware is faulty.. Read this thread about possible solutions...
