    Frequent BSOD screens - WinDbg referred probable cause to ntoskrnl.exe


    Hello Guys,

    I'm new to this forum and after days with problems on PC, I decided to get a help from better experienced people from this forum.

    Recently I have had lots of BSOD screens on my PC, sometimes happening when I'm playing 3D games, sometimes just the simple fact of starting the PC causes it to crash many times.

    Most BSOD refers to IRQL_NOT_LESS_OR_EQUAL error.

    Even right now, while I was creating this thread, the system suddenly crashed, screen got corrupted and I had to reboot.

    The interesting fact is that sometimes it crashes even at BIOS, making screen FREEZE. I have checked mobo and CPU temp., which are OK, I have even passed a memory test using Windows Memory Diagnostic Tool - which encountered NO errors.

    I'm suspecting these crashes started after I UPDATED ATI Drivers to version 12.8 (I have a Radeon HD5850), so I UNINSTALLED Catalyst software and maintained ONLY drivers. Even after doing this, the crashes still occur.

    Because I don't know how to read minidumps neither I'm expert at debugging, I want help of you to clear my doubt about WHAT is causing crashes.

    As instructed, I have uploaded the zip file with SF_Diagnositc_Tool.

    Please, if any of you can help, I'd be grateful.

    Thanks,
