Windows 7 Again on BSOD when waking up from sleep and sleep-hybernate enabled

[Blutarsky]

Good morning people,
I'm experiencing lately this problem: when turning on the computer from sleep, a BSOD will occur, not with the same error code.
I have performed a memory test with Microsoft diagnostics tool but no error was issued.
The computer is a Dell Vostro 1500, originally shipped with Vista 32 Ultimate, upgraded to Windows 7 Ultimate 32.
I have attached the minidumps.
I hope someone can help!

Little sysinfo, possible to attach more if needed.
